Red Alert 15
警戒Lv.15
Red Alert 15 is a Battle Cats stage in Heralds of The End. It costs 130 energy and sends 8 enemy spawn lines — led by The 9th Angel (Enemy) as the boss — against a 950,000 HP enemy base, and clearing it rewards 18,330 XP. Its enemies carry the Angel, Eva Angel and Red traits, so cats that target them do the most work here.
