Awash with Spare Keys
増殖するスペアキー
Awash with Spare Keys is a Battle Cats stage in Forgotten Republic. It costs 200 energy and sends 9 enemy spawn lines — led by Commander Ostromeda as the boss — against a 1,700,000 HP enemy base, and clearing it rewards 482,220 XP. Its enemies carry the Zombie, Alien, Floating, Black and Sage traits, so cats that target them do the most work here.
