This weapon does double damage if Tifa under the “HP Critical”, “Poison”, “Sadness”, “Silence”, “Slow” or “Darkness” status effect. It is triple if she is under the “Death Sentence” or “Slow-numb” status effect. You can invoke the “Death Sentence” status effect by equipping her with a Curse Ring.
Tifa’s Ultimate Weapon. It’s damage is calculated based on how full her Limit Break gauge is (higher if she is closer to having a Limit Break) which makes this a difficult weapon to fully utilize.
