Merc Awakens (Veteran)
メルク進化への道 超上級
Merc Awakens (Veteran) is a Battle Cats stage in Merc Awakens!. It costs 150 energy and sends 13 enemy spawn lines — led by Merc & Cat as the boss — against a 200,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
