Dangerous Equations

あぶない方程式

Dangerous Equations is a Battle Cats stage in Spring for Sensei. It costs 210 energy and sends 8 enemy spawn lines — led by Ms. Madonna as the boss — against a 350,000 HP enemy base, and clearing it rewards 18,753 XP. Its enemies carry the Alien, Black and Zombie traits, so cats that target them do the most work here.
