Revenge of Carnage (Merciless)
羅刹街道 超極ムズ
Revenge of Carnage (Merciless) is a Battle Cats stage in River Acheron. It costs 200 energy and sends 8 enemy spawn lines — led by Hannya as the boss — against a 999,999 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Zombie and Red traits, so cats that target them do the most work here.
