Strike Shift is a technique that appears in Kingdom Hearts III Re Mind. It allows the user to throw their Keyblade at an enemy and teleport to it, leaving behind speckles of light and dealing Physical damage.
In Kingdom Hearts III Re Mind, Strike Shift is an action ability exclusive to Kairi. It activates if Kairi is a certain distance from an enemy. If Strike Shift is used during the combo, then Kairi's combo finisher changes to Spiral Bloom instead of her default one.
