Clash of Steel (Merciless)
太古のメタル採掘所 極ムズ
Clash of Steel (Merciless) is a Battle Cats stage in 進化の古代マタタビEX. It costs 0 energy and sends 7 enemy spawn lines — led by Sir Metal Seal as the boss — against a 500,000 HP enemy base, and clearing it rewards 28,200 XP. Its enemies carry the Metal trait, so cats that target it do the most work here.
