Frontier Shrine (Merciless)

秘境の祠 超極ムズ

Frontier Shrine (Merciless) is a Battle Cats stage in Bad Instinct's Refuge. It costs 100 energy and sends 9 enemy spawn lines — led by Medu-san as the boss — against a 800,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Aku trait, so cats that target it do the most work here.
