Realm of Carnage (Deadly)
修羅の道 極ムズ
Realm of Carnage (Deadly) is a Battle Cats stage in River Styx. It costs 200 energy and sends 15 enemy spawn lines — led by Hannya as the boss — against a 666,666 HP enemy base, and clearing it rewards 17,860 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
