Final Fantasy Hacktics

Hello, i'm new to this, i love this game and recently found this site, being able to customize this game is fun, but i got that crystalize crash. Searching around this forum a bit, I see people post that changing the crystallization text or something. Problem i'm having is, i don't know where I can find it ^^, can someone help me? or is there a good guide for FFTactext which can help me out ^^.

EDIT: Right now i made all classes unable to crystallize, tho I'd prefer a more elegant solution.
