Ruins of the North
北の廃墟
Ruins of the North is a Battle Cats stage in Seeing Red ∞. It costs 110 energy and sends 9 enemy spawn lines — led by Dark Emperor Nyandam as the boss — against a 150,000 HP enemy base, and clearing it rewards 15,510 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
