I was planning to write a question about how a creature with a mutant healing factor -- a la marvel comics -- could be slain. I plan to describe the creature, it's attributes, then the proposed method of killing it.
(Please do be aware that this is a last resort; many attempts at negotiation, cultural exchange, and detente have failed. It is necessary.)
Is this worldbuild-y enough to be on topic here? It's kind of the opposite of the usual xenobiology question, which leans toward building a creature, while I, from sad necessity, plan to ... un-build it.
