VIIGreased Lightning is the initial Limit Break for Yuffie, which deals non-elemental physical damage to one enemy equal to 31⁄8 times normal damage. Using Greased Lightning 8 times will unlock Clear Tranquil.
Greased Bolt is an ability of the Warrior class, learned for 300 AP from the Gale Sword. It inflicts physical damage to one target (the element of the ability is the same as the equipped weapon) while ignoring the target's Reaction Abilities.
