Otherworld Colosseum · Stage 4
Round 4
Round 4 is a Battle Cats stage in Otherworld Colosseum 4. It costs 200 energy and sends 8 enemy spawn lines — led by Henry as the boss — against a 1,800,000 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Metal, Floating, Red and Black traits, so cats that target them do the most work here.
