Otherworld Colosseum · Stage 5
Round 5
Round 5 is a Battle Cats stage in Otherworld Colosseum 5. It costs 200 energy and sends 10 enemy spawn lines — led by M. Ost as the boss — against a 2,000,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Angel, Relic and Floating traits, so cats that target them do the most work here.
