Cultural Exchange Lv.8
異文化交流 Lv.8
Cultural Exchange Lv.8 is a Battle Cats stage in Island Defenders!. It costs 100 energy and sends 10 enemy spawn lines — led by South Seas Otter as the boss — against a 650,000 HP enemy base, and clearing it rewards 14,100 XP. Its enemies carry the Black and Alien traits, so cats that target them do the most work here.
