remember the iron siege?

[Daniel678]

Several things, diplomacy is given huge penalties since it is broken. I do not suggest relying on it.

People are trying to take him on head-on because he almost never leaves his tower. The only time he leaves is for the meeting with the 8 other Lords of the Nine. Players can't gain entry to the tower legitimately and so going commando is by far the simplest solution. It is also the one that has been the most successful. There has been at least one attempt at diplomacy but it didn't go anywhere. That said, some strategies that might work are, summoning him from outside the tower/plane, persuading him that the tower is dangerous, or ambushing him while he is traveling to the meeting (I forget the name) with the other lords of the 9. If you kill Dispater outside of Dis you don't kill permanently but you do get information and his items. If you immediately go to kill him on  Dis he will be lacking buffs and might be a little disorientated.

Counterspelling is nice to have. The SDA instant counterspell will give you everything you want.

Good luck with the challenge.

The most irritating thing for me is that you're forced to start in Dis, while it'd be far simpler to hijack a preexisting summoning.

[Daniel678]

I'm pretty sure that starting in Dis was more for convenience and you are not forced to do it if you don't want to.

If I recall correctly you start in Dis because Dispater stopped astral links and planar portals and so you start by entering with a custom epic teleport spell.

Nah, it's mandatory. A lot of builds end up immediately leaving after some plausible reason for being there in the first place is established, simply because a lot of important preparations can't be carried out beforehand or because some other route of approach is preferred.

For anybody's convenience for anyone looking for ideas, I've spoilered my entry below as it stood last time I worked on it. Everything in it was approved, IIRC, but of course it's always subject to Tshern's will.

Notable Factors: Incorporeal (Dry Demi) Lich Deity is a difficult-to-kill position by default. Levels in Entropomancer let him hide in a buffed Sphere of Annihilation (which, presumably, blocks line of effect to all non-Entropomancers, but I hadn't got around to asking that; Tshern's mileage may vary). Levels in Void Incarnate make him very difficult to track, and provide Force immunity. Remember, thanks to a throwaway line in Creating Monsters in the Monster Manual, you use Charisma for setting all save DCs ordinarily based on Con, so the save Dispater needs to make for Iron Curtain is set by Cha.

Andross, The Everlasting Know-It-All, The Infosphere

Alignment: Lawful Evil
Portfolio: Death, Fate, Knowledge
Worshippers: Liches, Unbodied
Cleric Alignments: LN, LE, NE
Domains: Knowledge, Fate, Oracle, Envy, Luck, Time

Andross is a deity of knowledge and secrets. He has often been described as Vecna on crack, if indeed stimulant drugs had any effect on undead deities. However, he does not mind sharing his secrets; in fact, it is said that anybody who journeys to his abode on the Negative Energy plane is given one completely true piece of information of their asking. This knowledge, however, often drives its learner insane, although this is of no consequence to Andross. His purpose in being is to learn all that there is to know, at any cost. He does, however, covet the knowledge he does not have, and envies those who possess it to the point of hatred.

He began his existence as a Lawful Neutral deity of knowledge, but over time he found that regard for lesser beings needed to be cast off to pursue his studies ever further. Early in his career, he became known to and worshipped by a small group of scholars in an ancient kingdom. These scholars eventually ascended to the beings now known as the Unbodied. It is said that Andross first discovered the secrets of lichdom, and shared them with ancient necromancers. It was Andross who found an alternate path in the way of the dry lich, and took that path himself. Andross was the first to ascend to the rank of demilich. If one is willing, one can trace many of the world's most vile pieces of knowledge back to this being.

Andross represents the cold pursuit of knowledge without regard to cost, and in this he is much like Mephistopheles. However, he pursues knowledge for its own end, not because it can be used for other purposes. When he finally understands everything, he plans to end the multiverse to ensure that no new knowledge can be created. Fortunately, his goal is not yet in sight, and many theorize that even threats so distant as the Overlord of Hell's rebirth are more imminent problems.

Overcoming Andross' Damage Reduction requires an epic, good, and wooden weapon blessed by 3 Celestials of each alignment on the Law-Chaos axis (total of 9 Celestials), all of which must have 21 or more hit dice. Furthermore, the weapon must then be soaked in the willingly given blood of a good-aligned Unicorn for a period of 24 hours.

COMBAT:
Immunities: Magic, poison, sleep, paralysis, stunning, disease, death effects, necromantic effects, mind-affecting effects, any effect requiring a Fortitude save unless it also works on objects, critical hits, subdual damage, ability damage, ability drain, energy drain, cold, electricity, fire, acid, sonic, force, polymorph, dehydration, heat.
Turn Resistance (Ex): Andross has Turn Resistance +28.
Telekinetic Force (Su): Andross can use telekinetic force (DC 15) as a standard action that does not provoke attacks of opportunity. Manifester level 4th. The save DC is Charisma-based.
Assume Likeness (Su): Andross can assume the likeness of any Small, Medium, or Large creature as a standard action that does not provoke attacks of opportunity. Its abilities do not change, but it appears to be that creature, relying on its Bluff and Disguise skills to deflect suspicion.
Hide Mind (Su): Andross cannot be identified as psionic by divination spells or clairsentience powers.
Incorporeal Traits: Andross is harmed only by other incorporeal creatures, magic weapons, powers, spells, spell-like abilities, and supernatural abilities. He has a 50% chance to ignore any damage from a corporeal source, except for force effects or attacks made with ghost touch weapons. He can pass through solid objects, but not force effects, at will. His attacks ignore natural armor, armor, and shields, but deflection bonuses and force effects work normally against them. An incorporeal creature always moves silently and cannot be heard with Listen checks if it doesn’t wish to be.
Skills: Andross has a +4 racial bonus on Bluff and Disguise checks. *When using his assume likeness ability, Andross gets an additional +10 circumstance bonus on Disguise checks. If he can read an opponent’s mind, he gets a further +4 circumstance bonus on Bluff and Disguise checks.
Trap the Soul (Su): Andross can trap the souls of up to eight living creatures per day. To use this power, he selects any target he can see within 300 feet. The target is allowed a Fortitude saving throw (DC 117). If the target makes its saving throw, it gains four negative levels (this does not count as a use of trap the soul). If the target fails its save, the soul of the target is instantly drawn from its body and trapped within one of the gems incorporated into Andross’s form. The gem gleams wickedly for 24 hours, indicating the captive soul within. The soulless body collapses in a mass of corruption and molders in a single round, reduced to dust. If left to his own devices, Andross slowly devours the soul over 24 hours—at the end of that time the soul is completely absorbed, and the victim is forever gone. If Andross is overcome before the soul is eaten, crushing the gem releases the soul, after which time it is free to seek the afterlife or be returned to its body by the use of either resurrection, true resurrection, clone, or miracle. A potential victim protected by a death ward spell is not immune to trap the soul, but receives a +5 bonus on its Fortitude saving throw and is effective against the level loss on a successful save.
Fear Aura (Su): Andross is shrouded in a dreadful aura of death and evil. Creatures of less than 5 HD in a 60- foot radius that look at him must succeed at a Will save (DC 63) or be affected as though by fear as cast by a 21st-level caster.
Paralyzing Touch (Su): Any living creature a demilich touches must succeed at a Fortitude save (DC 117) or be permanently paralyzed. Remove paralysis or any spell that can remove a curse can free the victim. The effect cannot be dispelled. Anyone paralyzed by Andross seems dead, though a successful Spot check (DC 20) or Heal check (DC 15) reveals that the victim is still alive.
Perfect Automatic Still Spell: Andross can cast all the spells it knows without gestures.
Magic Immunity (Ex): Andross is immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and effects function differently against him, as noted below. A shatter spell affects Andross as if he were a crystalline creature, but deals half the damage normally indicated. A dispel evil spell deals 3d6 points of damage (Fort save for half damage). Holy smite spells affect Andross normally.
Phylactery Transference (Su): Headbands, belts, rings, cloaks, and other wearable items kept in close association with Andross’s phylacteries transfer all their benefits to him no matter how far apart Andross and the phylacteries are located. The standard limits on types of items utilized simultaneously still apply.
Undead Traits: Immune to poison, sleep, paralysis, stunning, disease, death, effects, necromantic effects, mind-affecting effects, and any effect requiring a Fortitude save unless it also works on objects. Not subject to critical hits, subdual damage, ability damage, ability drain, or energy drain. Negative energy heals. Not at risk of death from massive damage, but destroyed at 0 hit points or less. Darkvision 60 ft. Cannot be raised; resurrection works only if creature is willing.
Immunities (Ex): Andross is immune to cold, electricity, polymorph, and mind-affecting attacks.
Damage Reduction (Su): Andross has damage reduction 15/Epic and bludgeoning. Vorpal weapons, no matter their enhancement bonus, ignore this damage reduction but do only half damage to a demilich (demiliches cannot be beheaded).
Aura of Despair (Su): Andross is surrounded by a terrible sense of age, loss, and death. Any creature within a 60-foot radius must succeed on a Will save (DC 88) or be shaken for 1d4 rounds. A creature that successfully saves cannot be affected again by Andross’s aura of despair for 24 hours.
Constitution Drain (Su): Any living creature Andross hits with its touch attack must succeed on a Fortitude save (DC 88) or take 1d6 points of Constitution drain. With each successful drain, Andross gains 5 temporary hit points.
Immunities: Andross has immunity to dehydration, heat, polymorph (though he can use polymorph effects on himself), and mind-affecting spells and abilities.
Unholy Toughness (Ex): Andross gains a bonus to his hit points equal to his Charisma bonus (Minimum +1) times his Hit Dice.
Water Weakness: All water deals damage to Andross as if it were holy water.
Scry Bonus (Su): Andross adds a +1 sacred bonus to the save DC of all his divination (scrying) spells.
Prescient Sense (Ex): If Andross makes a successful Reflex saving throw against an attack that normally inflicts half damage on a successful save, he instead takes no damage, since his prescience allowed him to get out of the way faster. This form of evasion works no matter what armor the divine oracle wears, unlike the evasion ability used by monks and rogues.
Trap Sense (Ex): Andross gains an intuitive sense that alerts him to danger from traps, giving him a +1 bonus on Reflex saves made to avoid traps and a +1 dodge bonus to AC against attacks by traps.
Divine Health (Ex): Andross has immunity to all diseases, including magical diseases such as mummy rot and lycanthropy.
Slippery Mind (Ex): Andross has the ability to shrug off magical effects that would otherwise control or compel him. If Andross is affected by an enchantment and fails his saving throw, one round later he can attempt his saving throw again. He only gets this one extra chance to succeed on his saving throw.
Shard of Entropy (Su): Twice per day, for a maximum of 10 rounds, Andross can create a miniature shard of entropy. The shard is a chunk of absolute blackness, 2 inches across, and can be moved up to 30 feet as a standard action. Against objects, the shard deals 7d6 points of damage, bypassing the object’s hardness. Against creatures, Andross must make a ranged touch attack to hit, and if successful the shard deals 7d6 points of damage to the target (Fortitude half, DC 65). The shard appears in any square adjacent to Andross when it is created, and it can be used to attack on the round it is formed. The shard of entropy lurches, jumps, and bounces around the square it’s in. Any creature who passes through the shard’s square takes damage as if the shard struck him (Fortitude half), as does any creature that’s in the  ame square as the shard at the beginning of Andross’s turn. Andross can move the shard into another square with a move action, or aim it at a specific creature (dealing damage immediately) as a standard action. The shard also exerts an inexorable tug on creatures nearby, pulling them toward the shard. At the end of Andross’s turn, the shard tries to pull creatures within 15 feet closer to it. This is treated as a bull rush attempt, for which the shard has a +11 bonus. If the shard wins the opposed check, it bull rushes creatures in a direct line toward its square. Andross isn’t immune to this effect.
Entropic Field (Su): As a standard action, Andross can surround himself with a field of invisible, entropic energy that lasts for 10 rounds. The field extends in a 50-ft radius, centered on Andross. All magical healing automatically fails within the entropic field. It takes the entropomancer
a standard action to dismiss the entropic field. The entropic field is strong enough to warp the laws of probability. Once per round, as a free action, Andross can force a character within the field (including himself) to reroll an attack, save, or check. Andross demands the reroll after he knows whether the attack, save, or check  ucceeded or failed, but before the exact consequences have been calculated and applied. The result of the reroll takes precedence, even if it’s worse than the original roll. The entropic field causes wounds created within it to continue bleeding, dealing an additional 1 point of damage per round thereafter (at the end of Andross’s turn) as long as they remain within the entropic field. A successful Heal check (DC 15) stops the bleeding. If multiple wounds are suffered, then the creature takes 1 point of damage per wound. Andross is subject to the bleeding effect.
Control Sphere (Su): Andross has the ability to control a sphere of annihilation as if he were using a talisman of the sphere, and Andross is personally unaffected by a sphere of annihilation, which passes through him as if his square were completely empty.
Blank Aura (Ex): Andross (and any equipment he wears or carries) radiates no aura of any kind. Detect chaos, detect magic, and similar spells simply register him as a blank. Andross cannot lower this aura. Andross can share this aura with three additional willing creatures (and their equipment) within 30 feet of himself. Granting the blank aura to one or more creatures within range is a standard action; the effect lasts for 24 hours or until Andross dismisses the aura as a free action. A creature sharing the aura must remain within 30 feet of the void incarnate (regardless of line of effect) to receive the benefit of the effect. If a creature sharing the aura leaves the range of the effect, the effect on the creature fades for the amount of time spent away from the void incarnate; moving back into range allows the creature to once again gain the aura’s benefits for the remainder of the 24 hours or until the creature leaves the area again, whichever comes first.
Improved Evasion (Ex): When subjected to an effect that allows a Reflex save for half damage, Andross takes only half damage on a failed save. Improved evasion can be used only if Andross is wearing light armor or no armor.
Void Presence (Ex): Opponents of Andross unconsciously ignore his presence. They are always treated as flat-footed to Andross (and thus may not apply their Dexterity modifier to AC). This lasts until he attacks the opponent, but resumes again at the start of Andross’s next turn. This is a mind-affecting effect. Andross can also use Bluff to create a diversion to hide as a move-equivalent action, rather than as a standard action. This ability has an interesting side effect. Anyone attempting to use Gather Information or similar methods to learn about Andross finds the task very difficult. Increase the DC of such tasks by 30.
Blank Mind (Ex): Andross is protected by a mind blank effect at all times. Andross cannot lower this aura, even to accept a harmless mind-affecting spell. Andross can share this effect with two additional willing creatures (and their equipment) within 30 feet of himself. Granting the blank mind to one creature is a standard action; the effect lasts for 24 hours or until Andross dismisses the aura as a free action. A creature sharing the effect must remain within 30 feet of Andross (regardless of line of effect) to receive the benefit of the effect. If a creature sharing the effect leaves the range of the effect, the effect on the creature fades for the amount of time spent away from Andross; moving back into range allows the creature to once again gain the effect’s benefits for the remainder of the 24 hours or until the creature leaves the area again, whichever comes first.
Null Strike (Ex): Once per day, Andross can declare any melee or ranged attack he makes to be a touch attack.
Improved Mettle of Fortitude (Ex): If subjected to an effect that allows a Fortitude save for a partial or half effect, Andross takes only the partial or half effect on a failed save (and no effect on a successful save, just as with mettle of fortitude).
Empty Form (Ex): Andross has a permanent freedom of movement effect (as the spell) on him at all times. Andross is also immune to force effects. Such effects either deal no damage (such as magic missile), don’t exist for him (such as wall of force, which he can simply walk through), or otherwise fail to affect the void incarnate (such as mage armor).
Improved Mettle of Will (Ex): Beginning at 10th level, if subjected to an effect that allows a Will save for a partial or half effect, Andross takes only the partial or half effect on a failed save (and no effect on a successful save, just as with mettle of will).
Sense Void (Su): The first technique taught to the void disciple is the ability to reach out with the mind and sense the world around, exploring the unseen layer of reality most people rarely experience. Andross’s consciousness actually departs his body and extends into the world, allowing him to use his normal senses (sight, hearing, touch, taste, smell) to perceive whatever area, person, or thing he directs his attention to. Andross can sense anywhere within 1000 miles of himself. Andross cannot sense across planar boundaries. Andross can use detect magic and detect evil at will. He can use discern lies and read emotional states, gaining a +10 bonus on Sense Motive checks. Andross can use this ability 6 times per day.
Moment of Clarity (Su): Andross can grant an ally the temporary ability to perform any skill or feat (with the exception of ancestor feats). Andross must use a standard action to touch the target. The target gains either one feat or a number of ranks in one skill equal to his relevant ability modifier for that skill. For example, a character with Dexterity 14 could gain 2 ranks in Ride, for a total skill modifier of +4. The effect lasts for 12 rounds. Andross can use this supernatural ability four times per day.
Altering the Course (Su): Once per day, Andross can add a +20 bonus on any single attack roll, skill check, or ability check he makes. He cannot transfer this bonus to another character by any means. This supernatural ability requires no action, and lasts only the duration of the single check.
Void Release (Su): Three times per day, Andross can touch an ally, allowing that character to use his highest ability score modifier in place of any one lower modifier (target’s choice) for a 6 rounds.
Void Suppression (Su): Once per day, Andross can make a melee touch attack to force the target to use his lowest ability score modifier in place of any one higher modifier (void disciple’s choice) for 5 rounds.
Aura of Evil (Ex): Andross has an overpowering aura of evil.
Detect Good (Sp): At will, Andross can use detect good as a spell-like ability, duplicating the effect of the detect good spell.
Poison Use: Andross is skilled in the use of poison and never risks accidentally poisoning himself when applying poison to a blade.
Dark Blessing (Su): Andross applies his Charisma modifier as a bonus on all saving throws.
Smite Good (Su): Once a day, Andross may attempt to smite good with one normal melee attack. He adds +41 to his attack roll and deals 2 extra points of damage . If he accidentally smites a creature that is not good, the smite has no effect but it is still used up for that day.
Improved Deflection (Su): Andross adds +2 to his deflection bonus to AC.
Superior Planar Summoning (Ex): Andross can increase the power of any of the following spells—elemental swarm, gate, greater planar ally, greater planar binding, summon monster IX, or summon nature’s ally IX—to affect or summon outsiders of 4 Hit Dice higher than the spell’s normal limit or conjure creatures with 4 Hit Dice of advancement.
Naturalization (Ex): For the purposes of spells and spell-like abilities that would normally affect creatures not native to Baator, Andross is treated as a native of that plane.
Alter Reality (Su): Andross exerts a considerable measure of control over reality itself, and his presence can command the very essence of the world around him. This warping of reality manifests in a number of ways. Andross can use wish at will with regard to his portfolio. This ability costs Andross no XP, and requires a standard action to implement. In effect, Andros can duplicate practically any spell effect, so long as the effect fits within the deity’s sphere of influence. In a situation where two deities both try to alter reality in opposition to each other, an opposed rank check may be necessary to determine the resulting reality. Similarly, where Alter Reality is used to change ongoing cosmic effects put in place by cosmic entities, an opposed rank check is required to determine whether the effect is overcome or not. Andross can cast any inflict spell at will. Andross can apply metamagic feats to the spells if desired, but doing so requires him to forego using alter reality for 1 round for each level the feat would normally add to the equivalent spell. As a swift action, Andross can assume any size from Fine to Colossal. Andross also can change the size of up to 100 pounds of objects he touches. This ability allows a deity to assume any proportions from the size of a grain of sand up to as much as 1,600 feet tall. A radical change in size can have great impact on Andross’s combat ability. Andross’s Strength, Armor Class, attack bonus, and damage dealt with weapons changes according to the size he assumes. Also note that use of this divine ability does not affect all of his characteristics.
Domain Powers: Andross can use any domain power he can grant 18 times per day (if the power normally can be used more often than that, he gets the greater number of uses). If a domain power is based on cleric level (or one-half cleric level), Andross is treated as Cleric 18 for this purpose.
Spell-Like Abilities: Andross can use any domain spell he can grant as a spell-like ability at will. His effective caster level for such abilities is 76. The saving throw DC for such abilities is 77 + the spell’s level.
Travel: Andross can use greater teleport as a spell-like ability at will, as the spell cast by a 20th-level character, except that he can transport only himself and up to 1800 pounds of objects. Andross also can use greater planeshift as a spell-like ability at will, as the spell cast by a 20th-level character, except that she can only transport herself and up to 100 pounds of objects.
Divine Aura (Ex): The mere presence of Andross can deeply affect mortals and beings of lower divine rank. Andross's divine aura has a maximum radius of 18 miles. He chooses the size of the radius and can change it as a swift action. If he chooses a radius of 0 feet, his aura power effectively becomes nonfunctional. When two or more deities’ auras cover the same area, only the aura that belongs to the deity with the highest rank functions. If divine ranks are equal, the auras coexist. Andross can make his own worshipers, Lawful Evil beings, or both types of individuals immune to the effect as a free action. The immunity lasts one day or until he dismisses it. Once affected by an aura power, creatures remain affected as long as they remain within the aura’s radius. Andross can choose from the following effects each round as a free action.
Daze: Affected beings just stare at Andross in fascination. They can defend themselves normally but can take no actions.
Fright: Affected beings become shaken and suffer a -2 morale penalty on attack rolls, saves, and checks. The merest glance or gesture from Andross makes them frightened, and they flee as quickly as they can, although they can choose the path of their flight.
Resolve: Andross’s allies receive a +4 morale bonus on attack rolls, saves, and checks, while his foes receive a –4 morale penalty on attack rolls, saves, and checks.
All divine aura effects are mind-affecting abilities. Mortals and other deities of lower rank can resist the aura’s effects with successful Will saves; the DC is 77. Andross is immune to the divine auras of any deities of divine rank lower than 18. Any being that makes a successful saving throw against Andross’s aura becomes immune to that aura power for one day.
Immortality: Andross is naturally immortal and cannot die from natural causes. Andross does not age, and he does not need to eat, sleep, or breathe. Andross is not subject to death from massive damage. The only way for Andross to die is through special circumstances, usually by being slain in magical or physical combat. He risks permanent destruction if slain on his home plane and if the attacker succeeds in a rank check. Otherwise, Andross reforms within his after one year per hit die of the attacker.
Divine Immunities: Andross is immune to polymorphing, petrification, or any other attack that alters his form. Any shape-altering powers he might have function normally on himself. He is not subject to energy drain, ability drain, or ability damage, and is immune to mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects). Andross is immune to Fire and Acid, regardless of the attacker. Andross is also immune to disease, poison, stunning, sleep, paralysis, death effects, and disintegration. In addition to these, Andross is immune to effects that imprison or banish him. Such effects include banishment, binding, dimensional anchor, dismissal, imprisonment, repulsion, soul bind, temporal stasis, trap the soul, and turning and rebuking. Unless otherwise indicated, these immunities are ignored on a successful opposed rank check (remember that a check must be made for each attempt to breach an immunity).
Checks: Andross can take 10 on any d20 roll.
Automatic Actions: Andross can perform any action within his portfolio as an immediate action as long as the check DC is equal to or less than 30. Andross recieves 20 swift actions per round, but can only use one of them for a swift-action spell.
Communication: Andross can understand, speak, and read any language, including non-verbal languages. He can speak directly to any being within 18 miles of himself.
Remote Communication: As a standard action, Andross can send a communication to a remote location. He can speak to any of his own worshippers and to anyone within within 18 miles of a site dedicated to him or within 18 miles of a statue or other likeness of him. The creature being contacted receives a telepathic message that only it can hear. Otherwise, Andross can choose to have his voice issue from any object not dedicated to another deity of rank 18 or higher. Alternatively, Andross can send an omen or manifestation. This ability functions across planes and any barrier. Once communication is initiated, Andross can continue communicating as a free action until he decides to end it. He can carry on as many remote communications at one time as he can remotely sense.
Create Items: Andross can create magic items related to his portfolio without the appropriate feats (but still must meet all other requirements). As a standard action, Andross can create a nonmagical object of any object related to his portfolio, which lasts for 18 days.

This was built in Spring '08, which means in terms of optimization-fu it is likely shit. So take it for what it's worth, which is probably less than the space it takes up.

Double post for Epic Spells and his personal Artifact, which couldn't fit in the last one.

Strengthen The Sphere
Transmutation
Spellcraft DC: 100
Components: Ritual, V, S, XP
Casting Time: 100 days, 11 minutes
Range: Touch
Effect: Negate Weaknesses in a Sphere of Annihilation
Duration: Instantaneous
Saving Throw: None
Spell Resistance: None
To Develop: 900,000gp; 18 days; 36000 xp. Seeds: Fortify (DC 27). Factors: Grant magical immunity (ad hoc +105 DC), Protect against Rod of Cancellation (ad hoc +10 DC), Protect against Gate (ad hoc +10 DC), make permanent (x5 DC), make instantaneous (x2 DC). Mitigating Factors: Increase casting time by 10 minutes (-20 DC), increase casting time by 100 days (-200 DC), 20d6 backlash (-20 DC), twenty additional casters contributing one 9th level spell slot (-340 DC), burn 4000 xp per caster (-800 DC)

This spell improves a Sphere of Annihilation. It requires 20 casters to assist the primary caster, each contributing one 9th level spell slot to the ritual. The primary caster, at the completion of the ritual, touches the Sphere to be enhanced. The spell grants no protection against the Sphere's destructive powers, and so the caster is almost always at least a 10th level Entropomancer. The Sphere is, thereafter, immune to any effect that allows spell resistance, as well as its normal weaknesses of the Gate spell and a Rod of Cancellation. Altering a minor artifact is not without its toll, draining 4000 XP from each caster involved in the spell, and exposing the primary caster to the Sphere's destructive energies, no matter what protections they might have; this effect deals 20d6 points of backlash damage.

Fragmented Phylactery
Transmutation
Spellcraft DC: 35
Components: V, S
Casting Time: 1 Minute
Range: Touch
Target: One or more objects, including the caster's phylactery
Duration: Permanent
Saving Throw: None
Spell Resistance: No
To Develop: 315,000 gp; 6 days; 12,600 xp. Seeds: transform (DC 21), Ward (DC 14).
This spell can only be cast by a lich. It either separates the lich's phylactery into multiple objects or expands the phylactery to include multiple objects. The number of objects can be no larger than the caster's modifier for its spellcasting ability. Thereafter, destroying the phylactery requires destroying each object, and so long as a single one exists, the caster cannot be destroyed permanently.
This spell can be cast repeatedly, increasing the number of objects comprising the phylactery by the caster's ability modifier each time.

Greater Esoteric Aegis
Abjuration
Spellcraft DC: 123
Components: V, S
Casting Time: 11 minutes
Range: Personal
Effect: 10-ft. radius emanation
Duration: 24 hours
Saving Throw: None
Spell Resistance: No
To Develop: 1,269,000 gp, 23 days, 44,280 XP. Seeds: ward (DC 14), transform (DC 21). Factors: gain +40 bonus on DC to avoid being dispelled (ad hoc +80), make spell effect tenacious (as per the feat) (ad hoc +10), end dispel checks that fail to dispel this spell automatically (ad hoc +4), ward against mage’s disjunction (+16). Mitigating factors: change range from touch to personal (-2), increase casting time by 10 min (-20)
The caster calls upon the very fabric of magic to fashion a ward to protect his own working of the Word from those that would tear it down. A shimmering, dusky globe surrounds the caster, intercepting any attempts to end his spells by means of dispel magic, or similar spells and epic spells, and providing a +40 bonus on the DC against which the dispel attempt must succeed. Any dispel attempt which succeeds can then proceed as normal, but greater esoteric aegis works as if under the effects of the Tenacious Magic feat, and thus cannot be dispelled, only suppressed for 1d4 rounds. Dispel attempts that fail are not entitled to checks against lesser spells within the area of effect (this differs from the usual procedure of area dispel magic attempts). Furthermore, mage’s disjunction is warded against in its entirety.

Warp Space
Conjuration [Teleportation]
Spellcraft DC: 65
Components: V, S
Casting Time: 1 Standard Action
Range: Touch
Target: You and touched objects
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No
To Create: 585000 gp; 16920 xp; 9 days. Seeds: Transport (DC 27). Factors: 1-action casting time (+38 DC), Transport by Other Means (+4 DC), Ignore Transportation Barriers (ad hoc +10 DC). Mitigating Factors: Damage on Miscast (ad hoc -4 DC), 10d6 backlash damage (-10 DC)
This spell bends the fabric of space around you, placing you in your desired location, before snapping back to its original arrangement; the only change when the spell is completed is that you are now at your intended destination instead of your location at the casting of this spell. Since this spell does not make use of interplanar travel, it cannot be disrupted by a Dimensional Lock spell or similar protections, nor are barriers of any sort between you and your destination a factor. In fact, there seems to be no known method of stopping the effect of this spell. However, if the user is unfamiliar with the destination, they must choose a direction and a distance to travel. If this movement places the creature inside an object, they are trapped and take 10d6 points of damage per round as their physical structure interferes with that of the surrounding material, although spells without verbal, somatic, or material components may still be cast (with an appropriate Concentration check for continuous damage). Unwise wizards have been found fossilized due to inaccurate uses of the spell. Incorporeal creatures are shunted to the nearest surface at a speed of 100 ft per round, taking 5d6 points of damage per round due to the natural instability of lurking so far from a surface, although if they survive they are expelled and take no further damage. Regardless of the result of the spell, the caster takes 10d6 points of backlash damage.

Blast Wave
Transmutation
Spellcraft DC: 273
Components: V, S
Casting Time: 1 Standard Action
Range: 3,000 ft
Target: One Creature
Duration: Instantaneous
Saving Throw: Fortitude Partial
Spell Resistance: Yes
To Create: 2,457,000 gp, 98,280 xp, 50 days. Seeds: Destroy (29 DC), Slay (25 DC). Factors: Increase to 160 HD (+8 DC), Increase save DC by 48 (+96 DC), Increase damage by 30d6 (+60 DC), Decrease Casting Time to 1 Standard Action (+38 DC), Remove Death descriptor (ad hoc +6 DC), Increase Damage Dice to d20 (+40 DC). Mitigating Factors: Take 20d6 backlash damage (-20 DC), Decrease range by 75% (ad hoc -4), Consume random spell slot (ad hoc -5 DC)
You unleash a tremendous wave of destructive energy, reducing your foe to a fine mist. The target of this spell must make a Fortitude save (at a DC of 68+your Key Ability Modifier) or be slain outright by the incredible energy channeled by this spell if they have 160 HD or fewer. If their save is successful, or they possess a greater number of hit dice, they merely take 50d20 points of damage. The caster of the spell takes 20d6 points of backlash damage from the energy of the spell, however, and the strain on their mind causes them to lose one randomly determined prepared spell or spell slot from a level between 1 and 9.

Heightened Awareness
Divination
Spellcraft DC: 250
Components: V, S
Casting Time: 100 days, 11 minutes
Range: Touch
Effect: Gain Information
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No
To Develop: 2,250,000 gp, 45 days, 90,000 XP Seeds: Reveal (DC 19), Foresee (DC 17). Factors: Change Personal to Area (+15), Change Area to Touch (+4), Various Effect Information (ad hoc +20 DC), Eliminate 10% chance of failure (ad hoc +10 DC), Make Dismissable (+2 DC), Change Duration to Permanent (x5 DC), Change Duration to Instantaneous (x2 DC). Mitigating Factors: 100d6 Backlash Damage (-100 DC), Increase Casting Time by 10 Minutes (-20 DC), Increase Casting Time by 100 Days (-200 DC), 17 Additional Casters Each Contributing 9th level Spell Slots (-289 DC), 1 Additional Caster Contributing a 6th level Spell Slot (-11 DC)

The caster grants himself incredible perception of the world's workings on the subject. The caster is immediately notified whenever the subject is targeted or otherwise subjected to any effect. The caster knows what sort of save is allowed, if any, and the DC of the save to within 10, although the spell reports a specific value; the actual save can be anywhere from 10 points higher to 10 points lower than the reported value. The caster knows whether the effect allows spell resistance. The caster is informed of any checks the effect makes, such as caster level checks or rank checks. The caster gains no information about the source of the effect, and only a brief description of what the effect was intended to accomplish (such as "Move via extraplanar travel to another location" if the caster were the victim of a spell such as Baleful Transposition), although appropriate skill checks may be made to identify a specific effect. This spell grants no bonuses to any saves, checks, or other statistics involved with the effect; it merely gives the caster knowledge of the aforementioned aspects of the effect. If the subject is not the caster, only the caster receives this information. The caster can dismiss the spell at any time, although its effects are otherwise treated as instantaneous and thus cannot be dispelled or interfered with by any means. A caster casting an epic spell on the subject can hide the details that the spell reveals with a successful opposed caster level check, resulting in the caster of Heightened Awareness being aware only of the fact that such a spell was cast; the caster of Heightened Awareness is not aware of the specific results of the caster level check, only whether or not it succeeded or failed. Salient Divine Abilities bypass this spell, unless the caster of Heightened Awareness is also a deity. In this case, an opposed rank check is allowed; on a success, the caster is aware of the Ability as though the deity using that ability had succeeded on the caster level check for an epic spell. If the caster fails, then the caster is not aware of the ability at all. Note that artifacts, no matter how powerful, do not count as epic spells or salient divine abilities.

Temporal Beam
The pair of soul gems comprising the Everlasting Know-It-All's temporal lobes double as a weapon. As long as both are attached to the same creature, the following effects can be used; both must be attached for the magic to be effective. Fortunately, these soul gems cease to function as such items upon separation from their owner's body, retaining only their weapon capabilities. The gems combined magical energy can produce beams of energy. Each beam functions as a +10 Ghost Touch Unholy Desiccating Profane Burst Distance Seeking Arrow fired from a Medium Longbow, although the base damage is 2d6 rather than 1d8, and the damage is untyped rather than piercing. In addition, any target struck by the beam gains a negative level; victims of a critical hit suffer 3 negative levels. Any victim slain by the beam is drawn into one of the temporal lobe gems, as a demilich's Trap the Soul ability, but with no save allowed (except on a successful opposed rank check, in which case the normal Fortitude save applies). Finally, each beam carries a dispelling effect. If a beam encounters a magical, psionic, or otherwise supernatural barrier or effect that prevents it from striking or otherwise affecting its target, the beam is allowed to make a dispel check (1d20+50). Supernatural effects use their creator's racial hit dice, if any, as the caster level to be beaten. This is an exception to the rule that supernatural effects cannot be dispelled. In any case, the beam does not continue through the barrier to strike its target; its magic is expended in the dispel check. Each beam requires a ranged touch attack to hit. Firing a single beam is an attack action. It is important to note that the items are as incorporeal as their current owner; only a Wish spell following the Everlasting Know-It-All's destruction can cause them to become corporeal, which allows for their installation in a corporeal being. Installing the gems in an incorporeal creature is a simple matter of placing them in the appropriate part of said creature, although the manipulation of the gems must be handled by Ghost Touch gauntlets. For corporeal creatures, the gems must first be rendered corporeal, at which point invasive brain surgery is required to implant them. The procedure requires a DC 40 Heal check to carry out properly, and even on a success the subject must make a DC 35 Fortitude save or die. The DC increases by 35 if the Heal check is failed. Naturally, Undead can simply shove them into their heads without worrying about undue consequences, and thus the above requirements do not apply (although the Heal check is often made anyway for the sake of appearances). The items do not function for any Construct or Plant.

[Ramaloke]

Is Illithid Savant allowed? Seems to me like an Illithid Savant + Stolen Thrallherd ability (for 2 more illithids with Illithid Savant) + Stolen Metamind's Font of Power + Fusion (We Are Legion) + Shrodinger's Cat Shenanigans should be silly enough to overcome the challenge.

Said character would be able to turn back time to the beginning of the challenge every time he met a "failure" and restart from the top. All enemies would roll natural 1s on every die roll, he would always roll natural 20s.

[Prime32]

Necromancy, eh?
Would some variant of this work? (add in Improved Cohort, familiar can gain Divine Ranks through "Nut-Pun" method, master is a primordial half-giant who was subjected to return to nature spam until he became Fine then swallowed)

EDIT: Ho?

EDIT2: Could a hairy spider build do well in this?

[Sippin]

The problem I have always had with the iron siege is twofold.
First the lack of openness of what the DM is actually doing. Secondly that Dispater gets to impose absolutes on beings equal in rank to him with no save or check.
At this level of play, things are so complicated that it is hard for the player to remember half of his abilities from 80 levels, hundreds of millions of gold in equipment, permanent buffs, etc. let alone the DM. Even past that, my opinion has always been that since this a challenge directly against the DM it is important for both parties to agree to any houserules that they want in effect.

With the way that the Iron Tower works, not even Pun-Pun could touch Dispater. It cant be destroyed in whole or part, has inescapable traps with no save and no check and is unaffected by essentially everything. Oh, and it is infinite. It was not written to be challenged. The only way to get to Dispater is DM fiat which is rather unlikely in a challenge where it is you vs the DM.

Our group is going to be running the Iron Siege here, but we are hashing out some changes to make it less arbitrary and actually beatable without fiat. Houserullings will be by consensus, full disclosure of abilities and effects is in play, no made up no save/check abilities/traps. Even that is not enough, still are trying to work out the nature of the Iron Tower itself.

[PhaedrusXY]

I can say that at least when Tshern was running it, the abilities he was using were 100% legit. He chose me as a "moderator" of sorts, and told me exactly what the NPCs were doing. I only performed this duty during one challenge, but I suspect everything else was "by the book" as well. It's just that as you said it is incredibly complicated due to the levels and abilities involved, not to mention minions, and the Iron Tower itself is nearly impregnable. There have been credible attempts to get into it, as well as at least one that seemed to be successful. Unfortunately, it led to the demise of the one using it...

But getting to Dispater is certainly the real challenge. Actually beating him is a snap for pretty much all contestants that have been entered.

[Sippin]

I have absolute confidence in the integrity of Tshern's challenges, I have no doubt that he did everything by the book.
 I still think full disclosure should be in effect however. I dont know if any houseruling came into effect on parts of what he did, but if so I would think the community should get some say on that. I may be in the minority, but I consider the player as an equal to the DM when it comes to houserules and custom material especially when this is a challenge of player vs DM. If for nothing else disclose so that the audience knows how they are doing those things. The challenge is biased against the challenger enough that even if they are allowed in character to know the exact mechanical effects Dispater and his minions use they still have basically no chance of winning.

By the rules Tshern could have all the other lords of the nine and every major demon in the nine hells show up between you and the Iron Tower. Unlikely setting wise, but not too difficult to make a excuse for (ancient pacts, prophecies, etc). Would that be fair for the challenge? There is no check and balance on the DMs power in the iron siege, it is futile unless the DM wants you to win. If it is going to be run as it is, there should be some constraints on both sides (no epic spell that outright kills Dispater;no saveless super traps so on).

As written the Iron Tower isnt nearly impregnable. It is utterly impregnable. Assuming you get to it, assuming you open the doors  (Dispater lets you) you can walk inside to a featureless, inescapable room, have the doors close behind you and be trapped forever. No save to avoid, no check to escape, cant knock down or damage the walls. Very difficult to teleport, pointless even if you can since the rest of the tower is the same and infinite in size and Dispater is so paranoid he has countermeasures to your every epic scrying spell.

Run Pun-Pun against the iron siege with every ability and class level there is. He still cant get to Dispater. Still cant get around the Iron Tower's defenses. The only chance he has is if the DM lets Pun-Pun have custom abilities or epic spells that enable him to get to Dispater. It is unbeatable as is and was never designed to be beaten.

[PhaedrusXY]

Tshern says otherwise, but he hasn't told me the specifics of how he thinks it can be beaten. He's holding out because he thinks someone might beat it someday. AFAIK, he didn't use any house rules at all except those found in the Dicefreaks pdfs and mentioned in the game setup thread. As you've said, it's not like he needs them...

[ImmortalSoul]

Showing everything to the players would imho make significant parts of the challenge rather pointless for those who read them to figure strategies for their own later attemps.

What I actually liked most about reading the attempts that have been made (and that I could find) and some of the character concepts was not actual rule mechanic anyway. This is partly because I don't know some of the rules (those for the Divine Ranks for example) and abilities used well enough, but also because I feel beating the system by actual rules is half of the challenge, at best. The entire rest is "being smart enough to really impress your DM" (which is, find the weak part in a seemingly unbeatable setting). On a certain level of optimization (where most of the challengers worked) the characters are solid enough, so obvious weaknesses in your builds are probably not the problem. The real challenge is finding the exact weak point your attempt is going to attack and utilize it.

[Tshern]

Daniel678: It is possible to enter the Tower. I've got an idea or few.

PhaedrusXY: Thanks for defending me.

Sippin: Full disclosure is in a way against the challenge. If I reveal all the tricks I use, all the challengers will be directly to be countering those shenanigans. For example, if you know you are going to face foes that stun you a lot, you'll want Freedom of Movement. A big part of the challenge is to simply figure out what the DM does.

Some random issues you raised:
-Dispater can call Dukes and other devils, not archdevils or Lords of the Nine. I, or any other of the DMs, has used other Lords or archdevils unassociated with Dis (Glasya and Merorem are the only ones).
-Checks and balances: A moderator, I've used PhaedrusXY and Mister Sinister.
-There are no saveless supertraps. Heck, I have not even used a single custom epic spell yes.
-Tower is not immune to teleporting through the means of Wish, Miracle and Alter reality.

A handful of general notes:
-I still maintain the challenge is beatable. By no means easy or even just difficult, it is a formidable task, but can be done. Not sure if I could do it, at least if I gave the new DM my notes on Dispater's tactics and tricks.
-No custom epic spells have been used from the DM's side.
-I think the main problem in the challenge is that it has been conducted by the same DM for so long. I have a rudimentary grasp of character optimization and I've had time to figure out defensive maneuvers.

Anyway, if there are any questions directly to me, I am willing to answer.

[The_Mad_Linguist]

Full disclosure is in a way against the challenge.

Fuck that.  I'm the goddamn god of secrets.

Full disclosure is in a way against the challenge.

Fuck that.  I'm the goddamn god ghost of secrets. 

Fixed.

Reveal us the answers then.

Energy Resistance (Ex): Immunity to acid, cold, electricity, fire and sonic.
Timeless Body (Ex): No more age penalties
Swiftness (Su): The character's speed doubles (this does not stack with any magical or supernatural enhancements to speed) and he gains the evasion ability (as the monk class feature). He also gains a +20 competence bonus on Balance, Climb, Jump and Tumble checks. Three times per day, he can act as though under the effects of a haste spell for 20 rounds.
Tongues (Ex): The character can communicate with any creature, as though under the effects of a tongues spell.
Aura of Menace (Su): A righteous aura surrounds the character when he is in combat or angry. Any hostile creatures within a 20-foot radius of the ascetic must succeed on a Will save to resist its effects. The save DC is equal to 47 + the ascetic’s Charisma modifier. Those who fail take a -14 penalty on attacks, AC and saves. This penalty lasts for 24 hours or until they successfully hit the ascetic. A creature that has successfully resisted or broken the effect cannot be affected again by the ascetic’s aura for 24 hours.
Special Abilities:
Exalted Warrior (Ex) – The ascetic's base attack bonus increases to +20/+15/+10/+5. This increase is applied before Epic modifiers.
Exalted Lifespark (Su)
You are constantly under the effects of Deathward. Additionally, you may Turn Undead, as a Cleric of 1/2 your level, a number of times each day equal to your Charisma modifier. If you can already Turn Undead, you Turn as if you were 5 levels higher in the class that granted the ability, and you receive Extra Turning as a bonus feat.
Exalted Grace (Ex)
The Ascetic's pre-Epic base save bonuses increase to Fort +12, Ref +12, Will +12.
Greater Exalted Grace (Ex)
The Ascetic may add his Charisma modifier as a Sacred bonus to saving throws. Prerequisite: Exalted Grace.
Exalted Magic (Su)
Any damaging spell the Ascetic casts is treated as Purifed and Consecrated, without increasing the casting time or using a higher-level spell slot. In addition, he receives a +2 bonus to overcome the spell resistance of evil creatures; this stacks with Spell Penetration and similar effects. The benefits of this power do not apply to any Spell-like or Supernatural abilities the Ascetic may possess.
Improved Exalted Strike (Su)
You may select a number of weapon enhancements, whose total "plus value" cannot exceed your Charisma modifier, to be applied to any weapon you wield, including natural weapons and unarmed strikes. You need not spend the entire amount at once, and may select new enhancements if your Charisma permanently increases in the future. Once chosen, these enhancements cannot be changed; this ability cannot be taken more than once. Note that selecting Holy or Holy Power would be redundant. Example: an Ascetic with 30 Cha (+10 modifier) could choose to make his weapons (and fists, claws, etc.) Speed (+4), Brilliant Energy (+4), and Flaming Burst (+2). If his Charisma later permanently increases to 32, he could add the Spell-storing property, as well.

Epic Spell and Power Details

Epic Consecrated Stealth Planar Bubble

Abjuration
Spellcraft DC: 76
Components: S, M
Casting Time: 10 minutes
Range: Personal
Duration: 60 minutes/level
Effect: 60-ft radius emanation centered on caster
Saving Throw: Will negates (Harmless)
Spell Resistance: No
To Develop: 684,000 gp, 14 days, 27,360 XP. Seeds: Planar Bubble (DC 26), Consecrate (DC 16), Magic Aura (DC 14) Factors: Increase duration to 60 minutes/level (+10), increase area to 60-ft radius emanation (+20), make tenacious as the feat (ad hoc +10) no verbal component (+2), ward against Mage’s Disjunction (ad hoc +16) Mitigating Factors: Change from Touch to personal (-2), increase casting time to 1 minute (-18) increase casting time to 10 minutes (-18)

This spell mimics the Planar Bubble spell as found in the Spell Compendium, but with an increased duration and area of effect, but as personal range spell, a tenacious spell, and warded against Mage’s Disjunction. The subject also radiates a permanent Consecrate effect over the area for the duration of the spell, and masks the magic auras of spells and magic items within the area, so they appear as nonmagical.

Cloak of Magical Invincibility

Abjuration
Spellcraft DC: 245
Components: V, S
Casting Time: 11 minutes
Range: Touch
Target: Touched Creature
Duration: 5 weeks
Saving Throw: Will negates
Spell Resistance: yes
To Develop: 2,205,000 gp, 88,200 xp, 45 days
Factors: +14(Seed: Ward) +220(Wards against all spells(and spell like effects, including those from magic items) increases by 11 levels) +68(Increase duration 3,400%, +34 days) +100(Increase caster level against dispel checks by 50 levels) Mitgating Factors: -100(Caster burns 10,000 xp) -57(three participants contributing an epic level spell slot)

Gives targeted creature immunity from all spells and spell-like effects with a spell level 12 or less for . Increases the caster level against dispel checks by 50 levels.

Superior Superb Dispelling

Abjuration
Spellcraft DC: 69
Components: V, S
Casting Time: 1 action
Range: 300 ft.
Target: One creature or object
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No
To Develop: 621,000 gp; 13 days; 24,840 XP. Seed:
dispel (DC 19). Factors: additional +70 to dispel check
(+70 DC), 1-action casting time (+20 DC). Mitigating
factor: 10d6 backlash (–40 DC).
As greater dispelling (see Chapter 11: Spells in the Player’s
Handbook), except that the maximum bonus on the dispel
check is +80, and you take 40d6 points of backlash damage.

Summoning Sanctuary

Abjuration
Spellcraft DC: 80
Components: Components
Casting Time: 1 minute
Range: Touch
Effect: 30-ft. spherical emanation
Duration: 24 hours
Saving Throw: None
Spell Resistance: Yes
To Develop: 720,000 gp; 15 days; 28,800 XP. Seed:
ward (DC 14). Factors: increase area of effect by 200%
(+8), increase bonus on caster level check to overcome
spell resistance by +20 (+40), determine creature type to
be warded against at the time of casting this spell (ad hoc
+4), prevent spiritual wounds within summoning area
(ad hoc +14).
This spell creates an area in preparation for summoning
a powerful creature. Proof only against physical attacks,
it prevents the next summoned creature, and all
other creatures of that type summoned into the area for
the duration of the sanctuary, from leaving a 30-foot
spherical emanation area by any means. The summoned
creature may be able to break past the barrier by means
of its spell resistance, in which case the caster makes a
caster level check with a +20 bonus.
Additionally, the typical effects of summoning a powerful
cosmic entity to the Prime are ignored if the creature
is summoned within a summoning sanctuary.

Esoteric Aegis

Abjuration
Spellcraft DC: 83
Components: V, S
Casting Time: 1 minute
Range: Personal
Effect: 10-ft. radius emanation
Duration: 24 hours
Saving Throw: None
Spell Resistance: No
To Develop: 747,000 gp, 15 days, 29,880 XP. Seeds:
ward (DC 14), transform (DC 21). Factors: gain +10
bonus on DC to avoid being dispelled (ad hoc +20),
make spell effect tenacious (as per the feat) (ad hoc +10),
end dispel checks that fail to dispel this spell automatically
(ad hoc +4), ward against mage’s disjunction (+16).
Mitigating factors: change range from touch to personal
(-2)
The caster calls upon the very fabric of magic to fashion
a ward to protect his own working of the Word from
those that would tear it down. A shimmering, dusky
globe surrounds the caster, intercepting any attempts to
end his spells by means of dispel magic, or similar spells
and epic spells, and providing a +10 bonus on the DC
against which the dispel attempt must succeed. Any dispel
attempt which succeeds can then proceed as normal,
but esoteric aegis works as if under the effects of the
Tenacious Magic feat, and thus cannot be dispelled, only
suppressed for 1d4 rounds. Dispel attempts that fail are
not entitled to checks against lesser spells within the area
of effect (this differs from the usual procedure of area
dispel magic attempts). Furthermore, mage’s disjunction
is warded against in its entirety.

The Circle of Locking the Nine Gates

Conjuration (Summoning)

In locking the Nine Gates, casters may either banish a Duke
of Hell from the mortal coil for generations (if not permanently)
or may permanently destroy a Duke of Hell.

The Duke of Hell is suddenly dragged from Hell and
forced into the center of the magic circle against evil.
The Duke finds that it cannot return to the Pit and that it
cannot summon or call allies for the duration of the spell.

If the caster hopes to destroy the Duke of Hell
the Duke’s entry into to the mortal coil is a painful one
as not only is the Duke forced to the Prime, but so too is
a portion of Hell. The simultaneous placement of these
two realities causes grave damage to the Duke; the Duke
immediately suffers 120 points of divine damage, with
no saving throw. The Duke does not regenerate this
damage during the duration of the spell (although he may
use other means to heal). At this point, the caster(s)
must enter the magic circle against evil in order to battle
with the Duke.

The Duke can attempt to breach the ward itself.
A Duke receives a Will save DC 99 in order to breach
one of the two wards one time during the duration of the
summons (note that in the event that the caster attempts
hostilities upon the Duke’s person, the save DC requirement
to breach the ward is removed, and the Duke instead
makes a caster level check to determine whether he
can ignore the wards by means of spell resistance).
Should the Duke attempt to breach the
wards surrounding him as described in circle of the Nine
Pits, he automatically suffers 120 points of damage per
attempt.

Whether the intent is to banish or to destroy the Duke,
the duration of the spell is always 27 rounds. If after that
time has elapsed the Duke is neither banished nor destroyed,
the spell ceases to function and the Duke is free.
It may summon or call reinforcements, may return to
Hell, or may wander the mortal coil for up to nine days.
Most Dukes, unless gravely wounded, are guaranteed to
exact immediate revenge against at least one of its tormentors
before retreating to slowly ruin the lives of other
living adversaries.

The circle of locking the Nine Gates can be adjusted
to summon more powerful Dukes, Arch-Devils, or even
a Lord of the Nine by sacrificing additional XP at the
time of casting to meet the CR requirement. Only the
primary caster is able to sacrifice this additional XP
amount. While a Lord of the Nine can be banished and
(theoretically) destroyed by this the use of the circle of
locking the Nine Gates, any successful binding achieved
upon a Lord lasts no more than 9 days. Woe to any foolish
enough to attempt this on a Lord-Regent of Hell.

XP Cost: 9,900 XP.

Extemporaneous Aura

Abjuration
Spellcraft DC: 198
Components: -
Casting Time: 1 standard action
Range: Personal
Effect: 300' radius centered on caster

Seed: Ward (14)
Factors: increase area 29 times +116, one action casting time +20, increase duration 100% +2, any contingent spell +36 (ad hoc), moves with caster +10 (ad hoc)

This spell suppresses the activation of all contingent spells or powers within a 300' radius. The contingent spells are not dispelled, but if their trigger condition is met, while within the radius make a caster level check using the CL of the contingent spell against the CL of Extemporaneous Aura. If the check is unsuccessful, the trigger does not activate. Once outside of Extemporaneous Aura's area of effect, suppressed contingent spells go off normally if their triggering condition continues to be, or is once again met. However, if the triggering condition is a specific event rather than on ongoing condition nothing happens until that event occurs again.

This spell completely cures an undead creature of all blindness, deafness, hit point damage, and temporary ability damage. It offsets feeblemindedness and cures mental disorders caused by spells or injury to the brain. It dispels all magical effects penalizing the character’s abilities, including effects caused by spells, even epic spells developed with the afflict seed. Living creatures subjected to this spell lose all but 1d4 hit points if they fail a Fortitude saving throw. Only a single application of the spell is needed to simultaneously achieve all these effects. This spell does not restore levels or Constitution points lost due to death.

Vs Casters

I have many different defenses and options when fighting casters. To begin with I can Counterspell any spell they cast as a free action by using either a spell-like ability or a spell. Such spells then rebound upon their caster. My Otiluke's Suppressing field spell suppresses any spell cast into or in it's range on a CL check so weaker casters may find themselves completely ineffective. Dampen Magic reduces the effect of any magic cast against me. I counter any spell that allows spell resistance and negate any spell that I save against. If any caster is able to affect me with any detrimental persistent effect I can seize control of it and change it's variables so that it no longer affects me.

Offensively I can pierce through spell resistance and have a wide variety of spells and spell-like abilities to choose from.

Buffs

He always has the listed persistent buffs active. He persists and extends all of them and casts them every day so he always has one set of spells up and usually has two. He buffs inside of an Innervated Speed and suppresses Dampen Magic while he is buffing. He casts an Extraordinarily Aimed Otiluke's Suppressing Field at one lower caster level than normal and then takes 10 on his caster level checks against it for the rest of his buff spells. He also uses Cunning Breach to penetrate his own spell resistance when casting any buff spells that would otherwise be negated by it. Additionally, every buff spell with a visual component is cast as an Invisible spell. Esoteric Aegis is cast while receiving maximum benefit from Cosmic Connection. Every spell with a radius greater than 60' is trimmed to 60' with mastery of shaping so that it is concealed with Epic Consecrated Stealth Bubble.

Abilities

Metamagic Effect: Aside from the obvious uses, I can use the corresponding epic feats to modify an harmful effect to not affect me through Extraordinary Spell Aim or apply Cunning Breach along with Purify to enhance it and make it not effect me. If I am unable to use Extraordinary Spell Aim on the spell effect and I need to get rid of it I can always reduce it's area to one square through Mastery of Shaping.

vs Dispater

Negated Abilities:

Aura of Hell, Hell's Fire, Perseverance Glance, Acedia's Influence,  The Might of Hell

Relevant Abilities

Ferric Affinity: Don't carry iron and if you are hidden the don't interact with iron. With Ironward you can avoid doing this by accident.
Interestingly, Dispater can animate slightly less than 8 square feet of Iron (or a greater amount of lighter iron alloys) at a time. This ability is a free action and therefore  Dispater is limited by the movement speed of the iron itself. Animate objects without legs or wheels have a maximum movement speed of 40' per round. As there is time for 2 move actions per turn Dispater can therefore move 38,400 pounds of iron 80' per round He could move less iron a proportionally further distance since he is limited only by quantity and not by actions.
By far the most dangerous part of this ability is that by using a move action he can gain LoS and LoE from any iron within the radius. He can use this ability to steal your time stops and cast his own without them being stolen. To to counter this move so that he need to constantly re-use this ability. Basically, this allows him to constantly attack you without any chance of reprisal. The only way to win this game is not to play.
One method that could be used to reach him could be to wish to be transported to the opposite side of the Ferric Affinity effect.

Iron Curtain: This ability has a long duration so expect it to be constantly active. Since Dispater can negate any attack with a very easy fortitude save there is no way attack him directly while this effect is active. Alter Reality can negate this on a successful opposed rank check. A Wish would be able to do it without requiring the save.

Spellcasting/Psionics: As per page 56 of the XPH the all of the psionic disciplines with the exception of Psychoportation powers are equivalent to a school of magic for the purpose of psionics-magic transparency. Since the Iron Siege uses psionics-magic transparency I can use Otiluke's Suppressing Field to negate all spells, powers, and items duplicating them which have a CL or ML less than mine. This does not include Psychoportation powers or spells from the Universal school. Unless Dispater has some CL increasing trickery or some other way around this trick he cannot affect me with normal spells. Also of note is that any spell targeting me has it's caster level reduced by 23.

Call Devils: It is within Dispater's capabilities to summon 9 Dukes of Hell to come to his aid.  None of the Dukes of Hell are strong enough to challenge me in a straight up fight although the possibility of distraction renders this ability a threat.

The Iron Tower

Spell Resistance negates the Dimensional Anchor effect.
Immunity to force effects negates the telekinesis.
High reflex saves and evasion negates the lightning bolts.
Immunity to mind effecting effects negates hold monster.
Esoteric Aegis negates the disjunction.

[The_Mad_Linguist]

Full disclosure is in a way against the challenge.

Fuck that.  I'm the goddamn god of secrets. 

Reveal us the answers then.

Dispater is unaware he possesses a deadly peanut allergy.

Basically you slip him a Snickers and call it good.
