Aku Studies 301: Inquiry

悪魔研究Ⅲ考察

Aku Studies 301: Inquiry is a Battle Cats stage in Empress' Report 3. It costs 100 energy and sends 8 enemy spawn lines — led by Lord Gravey as the boss — against a 900,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Zombie, Aku and Angel traits, so cats that target them do the most work here.
