The Devil's Rhythm (Merciless)
悪魔の律動 超極ムズ
The Devil's Rhythm (Merciless) is a Battle Cats stage in Temptation's Rhapsody. It costs 200 energy and sends 12 enemy spawn lines — led by Possessed Empress as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Aku, Black and Angel traits, so cats that target them do the most work here.
