Fate originally had the Improved Familiar and Spell-linked Familiar feats, but retrained them some time between A's and StrikerS - hence Arf reverted to a weaker form and stopped aiding her in battle.

Ragnarok:

Hayate takes longer to cast her spells than other casters, and needs both a chanted aria and to have the Book of the Night Sky at hand - this is represented by Snowcasting (which requires a move action to gather snow) and Elder Giant Magic, and Primitive Caster to add verbal and material focus components. This also represents her immense power. (her CL can get as high as 29).

For spells which appear on the wu jen's Water list she can use her Rod of Elemental Might to increase the CL by an additional +2 if she succeeds on a DC 26 Use Magic Device check. Her Ankh of Ascension can boost it by +4 3/day. Reserves of Strength can increase it by +3 in exchange for stunning, while also removing damage caps. So her maximum CL is 38.

Her lack of low-level magic is represented by Versatile Spellcaster (combine two spell slots into one a level higher) - the spontaneous casting requirement is handled by her runestaff.

As a "mage knight", Hayate has the Southern Magician feat to represent her combination of Belkan and Midchildian magic. This also qualifies her for the Attain Familiar and Improved Familiar feats, if you want Zafira for some reason. (Zafira: *sobs silently*)

Jermlaine (ritual of alignment) Cleric (Knowledge, Winter) 12/Fiend of Possession 6
NG Tiny Outsider (evil)
Feats: Cold Focus, Educated, Greater Cold Focus, Knowledge Devotion, Otherworldly
Spells: Enlarge person(?) - needs something that works on Outsiders

While Hayate has the Frostburn feats which make cold spells stronger, Rein has the ones which make them harder to avoid. Hayate is "a total clutz" without Rein. She is also not as useful possessing characters who do not specialise in cold magic, though they should still find the +5 attack/damage from Knowledge Devotion welcome.

If Rein having the ability to speak to rats weirds you out, apply the dragonborn template. This also lets her pick up a fly speed.

Friedrich
Young gold dragon (wyrm of war archetype) Warlock 1
