First Round (Deadly)

一の修練 極ムズ

First Round (Deadly) is a Battle Cats stage in The Proving Grounds. It costs 500 energy and sends 7 enemy spawn lines — led by Super Metal Hippoe as the boss — against a 650,000 HP enemy base, and clearing it rewards 44,650 XP. Its enemies carry the Zombie, Metal, Alien, Black and Angel traits, so cats that target them do the most work here.
