I dual classed Yoshimo to a fighter because he has the stats for it and found that keeping him on his "thief adventurer" AI script, even as a low level fighter he could still detect traps at his high percentage level. He just can't disarm them. (But you can walk around or knock them). Anyway, this trick should make life a lot easier for those who made a thief and dual classed. You don't have to keep a thief in your group while you wait to regain your thief skills.

There are a lot of potential exploits when it comes to scripts. I'm still trying to figure out if it's possible to get a character to force-cast a spell using a script.
