Panic would probably work very well, especially at the first part of Veil, Most of the mobs in Gloom, and the big room in Foundry.
I'd definitely look into that and probably a ER prot/infuser ele.
As for Damage I'd say Ineptitude, Energy Surge, Defile/Desecrate Enchantments, Wastrel's Worry/Demise, VoR (not if using panic), or something along those lines. You want alot of strong, armor-ignoring aoe, not single spike damage (Discord.)
Some nice support skills would be stuff like Enfeebling Blood, some random, cheap enchant removals, Convert Hexes, etc.
If you reeeeeaaally want to make it easy and can afford it, grab some consets and a few Powerstones.
