Every 10 seconds after the start of the battle, tears open a space to summon 6 squads of Hell Sirens, inheriting 40(100)% of Ao Run's soldier's HP (Damage dealt and damage reduction increased by 12(30)%, and 20(50)% damage dealt is restored to Ao Run, lasting for 30 seconds). At the same time, grants all Hell Sirens on the field a shield equal to 20(50)% of their max HP for 6 seconds, dispellable. Every time Ao Run takes enough damage equal to 10% of max HP, she will retreat into the void for 3(3) seconds, with a cooldown of 10 seconds.
