Aku Altar's Seal
悪魔城の封印
Aku Altar's Seal is a Battle Cats stage in Imminent Disaster. It costs 200 energy and sends 15 enemy spawn lines — led by Relic Bun-Bun as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 321,480 XP. Its enemies carry the Relic and Aku traits, so cats that target them do the most work here.
