Diamond Dust

The Diamond Dust (ダイヤモンドダスト) is a Keychain for Sora's Keyblade which appears in Kingdom Hearts Final Mix and Kingdom Hearts: Chain of Memories.

In Kingdom Hearts Final Mix, the Diamond Dust is a reward for defeating Ice Titan in the Gold Match. In Kingdom Hearts: Chain of Memories, the Diamond Dust can be randomly found on the 11th, 12th, or 13th floors after defeating Marluxia for the first time.

Design
The Keyblade appears to be made of ice, and both the teeth of the blade and the keychain's token are snowflakes. The Keyblade's name is based on the traditional attack of the Final Fantasy summon, Shiva; Vexen and Aqua also have "Diamond Dust" techniques, with the same origin.
