Decking Evil in the Schnoz!

[Zombulian]

Hmm...Many of these are classes I have not yet heard of, so I'll go do some research.

In the meantime, using classes I know of, would a warlock (or cleric)/barbarian/unarmed swordsage who channels his powers through gauntleted fists work? And what sort of role would it wind up filling, tank or MASSSSIVE DAAAMAAAAAGE?

Probably consistent damage output. Little bit tanky just because of Barbarian.
Clawlock with Beast Strike + DMM Persist Cleric Divine Power + Hellfire Warlock + Legacy Champion is the massive damage one. Each of your claw-fists pretty much blows enemies up with Hellfire. With a Cleric-zilla you wouldn't even need Barbarian in there. In fact you could just get the Rage spell for effect if you want.
