The Aku Realms — Stage 40
茨城県
The Aku Realms — Stage 40 is a Battle Cats stage in The Aku Realms. It costs 173 energy and sends 10 enemy spawn lines — led by Wicked Face as the boss — against a 800,000 HP enemy base, and clearing it rewards 12,700 XP. Its enemies carry the Aku, Black, Angel and Alien traits, so cats that target them do the most work here.
