Underground B18F
地底18層
Underground B18F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 30 energy and sends 7 enemy spawn lines — led by THE SLOTH as the boss — against a 350,000 HP enemy base, and clearing it rewards 1,692 XP. Its enemies carry the Aku trait, so cats that target it do the most work here.
