i have a kensai/thief, who is mastered in the use of the quarterstaff, and two-handed weapon style. dual him at level twelve, so you can get the extra benefits from the kensai, otherwise, do it at level nine, or fifteen. preferably nine or twelve though. also, put some points into a sword or dagger, so you can backstab. i say dual at nine now that i think about it. if you can get him as high as possible, ASAP, you can give him the use any item ability, and he can wear mages robes with the ac benefit.
