Another question - I'm a wizard and have found a couple of good staffs, dealing spiritual and shadow damage. What kind of skills should I develop to become more proficient with these items?
There is not a weapon expertise for spiritual damage based weapons. For the other, you would need the warrior skill 'two handed shadow' (taught by Sir Achim in the cursed abby in act 2, or by Olaf in the BF any act).
