Fury of Hell (Merciless)
絶撃の魔渦 超極ムズ
Fury of Hell (Merciless) is a Battle Cats stage in The Greatest Diablo. It costs 200 energy and sends 16 enemy spawn lines — led by Aku Cyclone as the boss — against a 2,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Aku, Red and Colossus traits, so cats that target them do the most work here.
