Hearscht: Silver Beast
夜明く銀の獣！ハルシュト
Hearscht: Silver Beast is a Battle Cats stage in Merc Storia: Attack. It costs 200 energy and sends 9 enemy spawn lines — led by Hearscht (Enemy) as the boss — against a 150,000 HP enemy base, and clearing it rewards 141,000 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
