I just realized , while trying to set something up, that Chameleons get no good save. Is this a typo? Man, that +3 Fort requirement for Ur-Priest is killer. You know, I bet the DM might even let Great Fortitude count for the requirement.... but would that be worth the feat? Decisions decisions...
Also, based on a Warlock->Ur-Priest->Eldritch Disciple sort of path, where would the best place to squeeze two levels of chameleon in? Is getting the floating feat early in the career more advantageous than getting Ur-Priest spells earlier? Is it worth it at all? I'm pretty sure it is (Extra Invocation + Crafting feats = win). Considering that the character will have some Warlock tricks to fall back on, how important is it to have Ur-Priest casting ASAP? Unfortunately, it's probably near-vital, huh.
Feat-wise, I was thinking Able Learner, Iron Will, Spell Focus: Evil, Quicken Spell, DMM:Quicken, Extra Turning , and two more.
Thoughts, criticisms, and advice is greatly appreciated.
