Alice regens from puddle

Drawing her army knife, she sliced the meat into ten parts and scattered them. Nine of the pieces stopped moving, but the largest part continued writhing. Its wounds healed so fast, she could see it happening. It was trying to re-form its human body.

Calamity Mary pulled out a bottle, cautiously opened the lid, and poured the contents over the meat. This was concentrated sulfuric acid imbued with Mary's magic. It would do worse than burn and inflame the skin. Smoldering white smoke rose from the flesh, and an awful smell, the kind that would hit your stomach directly, wafted up and dispersed in the wind. The acid opened a hole in the floor of the classroom, but the lump of meat was still moving. Mary poured out a second and then a third bottle of the acid. She would erase this thing and make sure not even dust was left.

The acid burned all the way from the third floor to the first, and Calamity Mary followed it down, pouring on more and more. The meat melted, the lump disappeared, and Mary pumped her fist in victory. She was wiping the sweat off her forehead, thinking she could feel relieved and go, when she realized the meat was re-forming within the sea of sulfuric acid. It was moving.
