Oncoming Storm (Insane)

進撃の暴風渦 超激ムズ

Oncoming Storm (Insane) is a Battle Cats stage in Red Sky at Morning. It costs Catamin A ×4 and sends 10 enemy spawn lines — led by The Perfect Cyclone as the boss — against a 900,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Floating and Black traits, so cats that target them do the most work here.
