Codependent Compound
共依存化合物
Codependent Compound is a Battle Cats stage in Yandere Chemistry. It costs 200 energy and sends 9 enemy spawn lines — led by Dark Dober as the boss — against a 1,800,000 HP enemy base, and clearing it rewards 482,220 XP. Its enemies carry the Red, Black and Sage traits, so cats that target them do the most work here.
