Teraphobic
モンスター恐怖症
Teraphobic is a Battle Cats stage in Merc Storia: Showdown. It costs 75 energy and sends 10 enemy spawn lines — led by Fuu (Enemy) as the boss — against a 60,000 HP enemy base, and clearing it rewards 10,575 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
