Upper Rank Three - Akaza (Insane)
上弦の参・猗窩座 超極ムズ
Upper Rank Three - Akaza (Insane) is a Battle Cats stage in Mission: Slay Akaza!. It costs 150 energy and sends 10 enemy spawn lines — led by Akaza as the boss — against a 1,500,000 HP enemy base, and clearing it rewards 21,150 XP. Its enemies carry the Relic and Black traits, so cats that target them do the most work here.
