Otherworld Colosseum · Stage 4
Round 4
Round 4 is a Battle Cats stage in Otherworld Colosseum 25. It costs 200 energy and sends 10 enemy spawn lines — led by Kappy Jr. as the boss — against a 2,600,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Floating and Relic traits, so cats that target them do the most work here.
