Undertow Coast

大潮の渚

Undertow Coast is a Battle Cats stage in Cats of a Common Sea. It costs 250 energy and sends 8 enemy spawn lines against a 1,100,000 HP enemy base, and clearing it rewards 602,775 XP. Its enemies carry the Angel, Zombie, Alien, Metal, Red and Floating traits, so cats that target them do the most work here.
