Collapse Checker
倒れてないか見る仕事
Collapse Checker is a Battle Cats stage in Drunken Foundry. It costs 190 energy and sends 11 enemy spawn lines — led by Metal Doge as the boss — against a 840,000 HP enemy base, and clearing it rewards 305,406 XP. Its enemies carry the Metal and Relic traits, so cats that target them do the most work here.
