Cultural Exchange Lv.9
異文化交流 Lv.9
Cultural Exchange Lv.9 is a Battle Cats stage in Island Defenders!. It costs 110 energy and sends 10 enemy spawn lines — led by South Seas Otter as the boss — against a 830,000 HP enemy base, and clearing it rewards 15,510 XP. Its enemies carry the Black and Alien traits, so cats that target them do the most work here.
