Gravity Break

Gravity Break (グラビティブレイク) is an ability that is exclusive to Kingdom Hearts Final Mix. It allows Sora's Keyblade to cast a miniature gravity spell by bringing back his Keyblade to slam a miniature gravity sphere in front of him with it.

Mechanics
In Kingdom Hearts Final Mix, Gravity Break is a combat ability that provides Sora with a combo finisher and has a 30% chance of occurring. It costs 2 to equip. Both the Keyblade and the Gravity itself have the same hitbox, and can only hit targets at equal ground level. Sora has a fast recovery time from this attack.

It does percentage-based damage equivalent to (40 + Strength)% of the enemy's HP.
