Archaeology 401: Planning
遺物調査Ⅳ計画
Archaeology 401: Planning is a Battle Cats stage in Empress' Excavation 4. It costs 100 energy and sends 11 enemy spawn lines — led by Infernal Pegasus Deonil as the boss — against a 1,050,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Relic, Floating, Behemoth and Red traits, so cats that target them do the most work here.
