4 Ranks of Profession (Diplomat) and an Acorn of Far Travel. And yeah, the Sacred Exorcist was to gain Turn Undead. The Dweomerkeeper idea took up exactly 4 levels, since it went Warmage 1/Rainbow Servant 10/Prestige Paladin 4/Last X 5. And actually, you really need Sacred Exorcist on all of them, meaning xxx 4. The DK build works because of Planar Touchstone. Now the Kobold just uses his race to sneak into UM for 10 levels, getting basically a progression to power metamagic, and then autopersist from Incantatrix and 1/day Godbuilding from DK. Prerequisite feats will need to be shuffled, but hey, that's what time independent planes and retraining are for
EDIT : If you guys would like, I can compile all of my builds (at least the ones I lay claim to the majority of the idea for) into a single thread, though I wonder if it should go on this forum or on the Guide subforum. Thoughts?
