Blade Ritual
鬼鎮めの儀式
Blade Ritual is a Battle Cats stage in Merc Storia: Mystery. It costs 90 energy and sends 10 enemy spawn lines — led by Todomeki (Enemy) as the boss — against a 150,000 HP enemy base, and clearing it rewards 12,690 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
