Diamond Dust (ability)

Diamond Dust is a technique introduced in Kingdom Hearts 358/2 Days. It allows the user to raise ice from the ground to freeze enemies.

Mechanics
In Kingdom Hearts 358/2 Days, Diamond Dust is Vexen's Limit Break. It summons three large mounds of ice that ascend from the ground to strike enemies, dealing ice damage and enemies. During the Final Limit, the three mounds of ice are replaced by one large glacier. This deals greater ice damage, continues to freeze enemies, and temporarily makes them gradually lose HP.

In Kingdom Hearts Birth by Sleep, Diamond Dust is a Command Style that can be used by Terra, Ventus, and Aqua. It is activated by using -related s or the Snow Bear ice cream item. When using Diamond Dust, the user gains an icy blue aura around them. Particles of ice emanate from the user's body as well. Terra, Ventus and Aqua's attacks become faster and deal ice damage. The standard four-hit combo deals Blizzard-type damage and the combo finisher consists of summoning three ice pillars that spin at a rapid speed. An ice pillar may be summoned during a combo. The finish command consists of the user producing a giant glacier, then bursting it around the user, dealing damage to nearby enemies.

In Kingdom Hearts Union χ, Diamond Dust is a special attack that targets all enemies. It costs 1 special attack gauge to perform. It moderately recovers HP and inflicts more damage the more turns have passed.

In Kingdom Hearts III, Diamond Dust is the basic Shotlock of the Crystal Snow Keyblade and has a max lock of 23. When activated, Sora hovers in the air and launches a series of ice blades towards enemies, with the amount of ice blades launched depending on the number of locks.
