Feathered
翼を与えられし者
Feathered is a Battle Cats stage in Merc Storia: Mystery. It costs 30 energy and sends 7 enemy spawn lines — led by Orthos (Enemy) as the boss — against a 15,000 HP enemy base, and clearing it rewards 2,820 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
