It depends what kind of necromancer you're playing, really.
You're early enough in the game that it doesn't really matter all that much. Just grab a wand with bonuses to skills you use (or a dagger if you're using poison dagger) and don't worry about it too much - you probably won't be swinging it, so your weapon is largely irrelevant outside of skill bonuses. --- I know the answer... what was the question again?
