But there's a tome spell that improves damage for dual wielding, so dual wielding wands with Wand Chaos and Ice/Fire/Lightning Brand can be pretty good also. since Wand Chaos will go off when you use the spammable spells.
I may look calm...but in my head I've killed you 3 times http://oi51.tinypic.com/118eyp1.jpg <--if CoD was like D&D
That's what I'm kind of doing now. I think I'm going to stick with that. I always enjoyed dual wielding wands in torchlight. I also really like the random meteors and bats and what not that comes from wand chaos. But is putting more than one skill point into a good idea?
Staff Mastery may have the technical edge, since the debuff is really nice, I believe it stacks, and you can debuff the enemy even further (such as with firestorm). Add to that all the ways you can supercharge your elemental spells and you can really lay the smack down on some bosses.
On the other hand, staves themselves kinda suck hard (stupid melee) and dual wands just looks badass.
One thing I've found the wand exceptionally useful for is generating that last bit of charge to activate your infinite mana thing when your MP is out. I mean, yeah you could chug a potion but that would be wasteful when you're two wand shots away from going super-sayian. With a staff you have to close in and find something to smack (and hope it doesn't smack you back in the process)
Then again, once you've got like 7-8 points into charge mastery it's not hard to fill the charge meter before zeroing out your MP.
Aside from that. Since most spells are based on right-hand weapon DPS. Staves would probably give you more bang for your buck for your level. Though if you one-hand a wand you can carry a shield in your offhand to further reduce your squishiness.
