Yep, DeadDancingShape got it right, it is in How but not in either of the BG games(or IWD for that matter). I think I read somewhere that it is implemented from the new 3rd edition rules, but am not sure. I agree with you DDS, I always want to do the one that I don't have selected.
By the way, I like your name Debaser. I wanna be, be a debaser...
