Aku's Murmur (Insane)
悪魔の呟き 超激ムズ
Aku's Murmur (Insane) is a Battle Cats stage in Growing Evil. It costs 300 energy and sends 10 enemy spawn lines — led by Le'noir as the boss — against a 600,000 HP enemy base, and clearing it rewards 28,200 XP. Its enemies carry the Aku and Black traits, so cats that target them do the most work here.
