The Aku Realms — Stage 42
宮城県
The Aku Realms — Stage 42 is a Battle Cats stage in The Aku Realms. It costs 179 energy and sends 13 enemy spawn lines — led by Le'Behemoth as the boss — against a 800,000 HP enemy base, and clearing it rewards 13,300 XP. Its enemies carry the Aku and Floating traits, so cats that target them do the most work here.
