Putrid Prison
薬品くさい牢屋
Putrid Prison is a Battle Cats stage in Secluded Cavy Island. It costs 220 energy and sends 14 enemy spawn lines against a 1,200,000 HP enemy base, and clearing it rewards 530,442 XP. Its enemies carry the Relic, Red, Sage, Colossus, Alien and Floating traits, so cats that target them do the most work here.
