Fever Time!
フィーバータイム！
Fever Time! is a Battle Cats stage in Moonlit City. It costs 120 energy and sends 9 enemy spawn lines — led by Belial (Enemy) as the boss — against a 200,000 HP enemy base, and clearing it rewards 16,920 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
