[Baal is a pretty good cover for Carmilla, technically.] Good move! [Cagliostro's Persona, being a giant snake, takes the job of curling up around the monster and trying to trap it with a squeeze. It lashes out a little, but all it does it maybe scratch Ouroboros superficially.]

Ow, ow. Come on, that's all you got?! [Cagliostro opens her bag and... Christ, this woman is mad. She's got a literal Molotov Cocktail, and god knows what else she's conjured up from the deep abyss that is the University level Chemistry labs of Green Valley. She tosses it at the monster, before calling Ouroboros to retreat.]

Alright! It's all drenched in oil! You got any magical spells that can make a spark? [Like Zio, for example? This cocktail is potent enough to explode with just a burst of lightning.]
