I'm sure there's a weapon or two in the game that can cast "miscast magic" upon hitting its particular target, which would certainly help against pesky mages. Having a couple of tanks with solid enough resistances to sit out their defenses would be mandatory though, as would the usual snipery surveilance. But when it doubt, hide and wait.

I started my most recent game as mostly neutral but have gradually been goaded into villainy (neutral evil). I love the evil characters and think ToB in particular really seems to tempt one into roleplaying in this direction. Be sure to give it another chance sometime, you won't regret it.
