The Tavern

If they are dessicated vessels incapable of eating and drinking, then how in the hell can they be poisoned? This makes zero sense, even in a wholly imaginary milieu.

poison bypassing the undead poison immunity sounds like a bug to me

Well I guess I better make sure I wasn't imagining it before I report such a thing. It's possible I confused the location of the mini-indicator icon (more than once). :/

Yeah, Mummies are supposed to be completely 100% immune to poison. Either you misunderstood something that happened or it's a bug.
