Archaeology 401: Methods
遺物調査Ⅳ方法
Archaeology 401: Methods is a Battle Cats stage in Empress' Excavation 4. It costs 100 energy and sends 14 enemy spawn lines — led by Infernal Pegasus Deonil as the boss — against a 1,100,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Zombie, Behemoth, Black and Red traits, so cats that target them do the most work here.
