Underground B30F

地底30層

Underground B30F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 300 energy and sends 4 enemy spawn lines — led by Mr. Mole as the boss — against a 600,000 HP enemy base, and clearing it rewards 1,692 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
