Fighting skills would definitely matter, but a wraith's spine (?), when used as she did the werewolf, should prevent the close contact that the djinn's poison would require. I don't know why a wraith would be immune to the djinn's poison, but a djinn can't spit its poison, right? I suppose it would also depend on how fast-acting the poison is.

But now that you raised the question, I am intrigued. How vulnerable are monsters to other monsters? If a djinn needs to be killed by a silver knife dipped in lamb's blood, could it succomb to a wraith's spine? Would a djinn's poison actually work on a wraith or vampire or werewolf? Could a werewolf kill everything by ripping hearts, except an arachne, which apparenly can only die by decapitation?
