Anyway, as far as it goes, fire barely fazes Velvet. It can burn her to ashes--one of the few things that can really actually discorporate her--but she'll put herself back together in her crypt at the next midnight. She might even thank Miyuki for doing it, it's honestly probably easier than dealing with the pain of injuries, even if they heal quick. Velvet is nothing if not obscenely hard to hurt in any meaningful way and you need to jump through way too many hoops to have a chance at killing her. The only spells that might be dangerous would be spell that conjure sunlight. For, yknow, obvious reasons.
Counterpoint: She asks Lilith and @Massasauga to pull a prank. It's called we do a little bit of trolling.
It's a two parter.
