I don't see a problem with it, you'd be an undead vermin.
Yeah, that's what it was looking like to me. Just wanted to make sure I didn't miss anything. I guess the WtW's DR 15/- would override the Lich's 15/ B&M, other than that it all looks like it should line up fine. *cackles*
I really want to know what the backstory will be. Did the Worm that Walks become a lich in order to make sure it didn't die again or did the lich get seal away with worms that slowly ate its undead body until it mutated into something even more horrible than it already was?
