Euler Archipelago
オイラーノ群島
Euler Archipelago is a Battle Cats stage in Restricted Area. It costs 250 energy and sends 11 enemy spawn lines — led by Deathkory as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 602,775 XP. Its enemies carry the Red, Aku and Sage traits, so cats that target them do the most work here.
