Nightsister allies have +50% Potency and +30 Speed. When a Nightsister ally uses a Special ability, they inflict Plague on the selected target for 3 turns, which can't be Evaded. When an enemy Resists a detrimental effect, Nightsister allies gain 5% Turn Meter. When a Nightsister ally uses a Basic ability during their turn, a random defeated Nightsister ally is Revived with 50% Health and called to Assist, then the Revived ally is immediately defeated unless an enemy was defeated (the Revived ally can't be Revived by this effect again until the end of the next turn).
