Hey everyone. I've played DDO a bit, but never as a caster and I've got a few questions on where to go with my Drow Wizard:

-What should my stat array be? Is there any need for Dex? Wis? Cha? Should my Int be 18, 19 or 20, starting?
-What spells are most worthwhile to take starting? Which are never really worth learning off a scroll?
-If I were to take a single level of sorcerer, does that grant be a significant boost to spellpoints? And, if so, is it worth setting myself back 1 Wizard for that?

-What the heck is efficacy? I keep trying to find a definition for this in DDO and continue to fail in that task.
-What are the best spells to use for the early solo missions?

-What sort of equipment should I be gunning for?
