Brotherly Income Gap
金額の差で兄弟喧嘩
Brotherly Income Gap is a Battle Cats stage in New Year's Bling. It costs 110 energy and sends 8 enemy spawn lines — led by Large Red Ball as the boss — against a 90,000 HP enemy base, and clearing it rewards 82,720 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
