The Gear Matrix (デコレーションマトリックス, Dekorēshon Matorikkusu?, lit. "Decoration Matrix") handles Data-Sora's equipment in Kingdom Hearts Re:coded, including Keyblades, accessories, and Finish commands. In effect, the Gear Matrix determines how the Overclock (オーバークロック, Ōbākurokku?) system is implemented.
As Sora successfully uses the Attack command and Deck Commands on enemies or certain objects, the clock gauge (クロックゲージ, Kurokku Gēji?) fills up. Each time the gauge fills completely, the clock level (クロックレベル, Kurokku Reberu?) increases by one, activating an ability on the equipped Keyblade's unique Clock Ability Tree (クロックアビリティツリー, Kurokku Abiriti Tsurī?) and moving on to the next tier. The abilities that will be activated on the tree can be selected on the touchscreen, or in the Gear Matrix. As a Keyblade chip levels up through use in battle, additional abilities will be unlocked on the tree.
When an endpoint on the tree has been reached, filling the clock gauge again changes the Attack command to activate the equipped Finish command. The higher the clock level is when using the Finish command, the more powerful it is. Once the command has been used, the clock level returns to one, and all abilities on the tree from level 2 and on will deactivate.
Finish command chips
Only one Finish command can be equipped at a time. There are three types of Overclock Finishers: Simple Type (シンプルタイプ, Shinpuru Taipu?) Finish Commands are marked with a light blue symbol, Command Input Type (コマンド入力タイプ, Komando Nyūryoku Taipu?) with a red symbol, and D Magic Type (D魔法タイプ, D Mahō Taipu?) with a purple symbol. Simple Type Finish commands are performed by pressing when prompted, and require no further interaction from the player. Command Input Finish Commands are performed by pressing when prompted, followed by pressing various buttons at specific times. D Magic Type Finish commands are performed by pressing when prompted, followed by using the D-Pad to aim, and tapping repeatedly.
Accessories can be obtained by redeeming SP in various System Sectors or by completing various quests. The initial amount of accessories that can be equipped is one, but by hooking up chips to Accessory Expansions in the Stat Matrix, up to three additional slots can be unlocked, and as a result, up to four accessories can be equipped at any one time.
