Which book is duskblade from? I believe they have a very limited spell selection, right? I'm not necessarily looking for overwhelming damage-dealing action. I would rather be able to disable opponents through spells like blindness and contagion and move to someone else, letting the tanks finish them off.
With dual wand wield, I could cast 2 spells per round from a wand, which would be some serious damage (or hold person and dimension door, then swap wands and blast.)
I also want the versatility of a wizard's spell list, and am willing to sacrifice damage for this.
