is this a power or a quirk or (animal rp question)

well, as a whole itd just be a hobby in dark magic with benefits, so the power would be necromancy. id say with practise she could reanimate anything nonsentient (maybe sentient for plot?) and probably no bigger than say, a lion. also the smaller the animal is, the more of them she could bring back at once. it wouldn't be able to be a whenever thing, since it'd be a wholly big drain of magic (??) or just stamina in general.
