Mine is definitely black necromantic. You can revive dead creature as your slave, you can cast cheap harms and quench life is really effective for assasination. Also, they're really cool, no one can resist the art of necromancy. Also, create undead is a very quick way to move corpse into a room without leaving blood trace.
Black necromantic is rather cool, although I haven't played a magic-user long enough. I like summoning as well. But when I start over the next time I'll build a necromancer, I think. X
well nothing is as good as the Temporal school when ure playing a fighter/mage, i mean how good isnt the stasis spell it totally parylazes the target and if there is many creatures the congeal time spell is awsome and when u get the last spell the Tempus fugit ure asskicking all the way to Valhalla!
