thanks for some of hte feedback
I was definitely not thinking of anything along the lines of a Beserker. And when I mentioned working against the party, I didn't mean trying to kill them, more like acting sort of randomly and interfering with strategy.
I don't want the character to be violent crazy, just sort of only partially in the "real" world (funny term here) and act bizarrely at times (though always following some strange internal logic). I was thinking Chaotic Neutral, but with Good tendancies (in his more lucid moments). He would generally work with the party, he can recognize friends and enemies, but doesn't always act like you would think or expect, or even want.
Definitely spell caster of some sort, and telepath was the only thing that really seemed to fit since arcane magic seemed to require too much concentration, and he isn't going to be the religious type.
I was thinking as a penalty he couldn't use and feats or skills that require "skill" and concentration, with the exception of artistic crafts. He also was going to avoid all weapons.
Anyway, thanks for the tips and suggestions, more are always appreciated.
