Gravity Break (グラビティブレイク, Gurabiti Bureiku?) 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.
In Kingdom Hearts Final Mix, Gravity Break is a combat ability unique to Sora which provides a 30% chance of unleashing a gravity-based finishing combo attack on ground targets that always deals a Critical Hit. It costs 2 AP to equip. It deals damage equivalent to (40 + Strength)% of the enemy's HP, unlike the original Gravity spell's damage calculation being based on magic/MP. After hitting the target, Sora takes 16 frames (0.5 seconds) to recover.
