Archaeology 301: Planning
遺物調査Ⅲ計画
Archaeology 301: Planning is a Battle Cats stage in Empress' Excavation 3. It costs 100 energy and sends 9 enemy spawn lines — led by Cumulus Gallus as the boss — against a 850,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Red, Behemoth, Relic and Black traits, so cats that target them do the most work here.
