Frontier Wilderness (Merciless)
秘境の樹海 超極ムズ
Frontier Wilderness (Merciless) is a Battle Cats stage in 進化素材ドロップEX. It costs 0 energy and sends 17 enemy spawn lines — led by Wicked Face as the boss — against a 750,000 HP enemy base, and clearing it rewards 18,800 XP. Its enemies carry the Aku trait, so cats that target it do the most work here.
