Field effect: Annihilation Wish: At start of every turn, grant all Anra Mainiiu an ATK Buff (1 turn) and a Critical Rate Buff (3 turns). Crit Rate buffs can continue to stack across turns.
There are a total of 100 Anra Mainiiu enemies. However, the battle will end upon the defeat of Emiya, so there is no need to kill all of them.
Upon 2nd Break: Sage of Celestial Spite: Apply Invincible to allies (3 turns) and self-inflict Stun onto self (2 turns). Seems to only cast this when there are three enemies alive on the field.
