Underground B72F
地底72層
Underground B72F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 50 energy and sends 8 enemy spawn lines — led by Cala Maria as the boss — against a 800,000 HP enemy base, and clearing it rewards 2,820 XP. Its enemies carry the Angel and Aku traits, so cats that target them do the most work here.
