リーグ解禁！ 激ムズ
難攻不落の城とドラゴン — Stage 1 is a Battle Cats stage in 難攻不落の城とドラゴン. It costs 100 energy and sends 13 enemy spawn lines — led by Cyclops (Enemy) as the boss — against a 400,000 HP enemy base, and clearing it rewards 14,100 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
