The Debug Ability, Debug Mode, or Area Debug is an ability that the Data-Sora uses to fight the Bug Blocks in Kingdom Hearts coded. Data-Sora generally has to use this ability every time he visits a world. Data-Sora must gather Debug Orbs to replenish the Debug Ability.
Special Area Debug
Automatically target the nearest enemy when pressing the attack key.
Confuse the enemy and make them attack each other.
Allows you to change into a different attack mode where you can shoot frozen enemies with blasts of ice. The more hits you score on the targets, the more VP you will earn.
Reduces the speed of your enemies.
You can now use the Trinity command. When the Trinity gauge is full, use it to unleash a powerful attack, as long as your friends are near you in battle. However, it cannot be used if your friends are knocked out. You should notice a Trinity gauge, now full, where your Debug gauge used to be. It fills the same way, by smashing blocks and defeating enemies. Using the Trinity works. You have to press direction arrows as indicated on the screen to make the attack stronger.
Restore Data-Sora's HP.
Halves damage in a crisis.
Allows Data-Sora to recover HP by damaging enemies.
Reflect enemy attacks and knock out your target.
Allows you to change into a different attack mode where you can aim at your targets with the direction keys.
Data-Sora becomes transparent and cannot be attacked.
Allows you to change into a different attack mode where you can strike your foes with balls of fire. The better your timing, the higher the chance of a critical attack, which also gets you more VP.
Attack freely with the direction keys during a reaction combo.
Reflect enemy attacks and knock out your targets.
Area Debug Mode
Instruction: Smash all the Bug Blocks before time runs out!
You have two minutes to take out three blocks. When you do, the screen flashes.
Instruction: Destroy the Bug Blocks before time runs out!
There are initially five purple blocks on the tiles, which form a heart shape under you. You have three minutes to get rid of the blocks. It works the same way as it did in the last two worlds.
When you finish, confirm your results and continue.
Instruction: Defeat the Heartless before time runs out!
The camera shows the maze from farther away, so you can see the whole thing at once. Initially, there will be two Shadows in the maze. Bug blocks appear under them at random intervals. Smash those to bring the heartless back down to your level. Damage blocks will rain down on Data-Sora, so try to keep moving to avoid them.
After you take out the first two Shadows, six more appear. Get them the same way. The rain of damage blocks will get a lot harder, falling in torrents at regular intervals. Don't get trapped in the dead ends. When all of the Shadows are gone, you're finished with this debug round. Confirm your results and move ahead.
Instruction: Defeat the two eyes of the tiger head!
You have a four-minute time limit to finish this fight.
The Cave of Wonders is spawning oversized bug blocks with legs (legged-blocks). Each of them will take a half-dozen hits to put down.
You'll notice a few floating metal blocks on either side of the Cave. You need to climb these to reach the eyes, which are your real target. However, the lowest metal blocks are still too high for Data-Sora to reach.
The way to get up there is to knock out one of the legged-blocks in the immediate vicinity of the metal blocks. The dead enemy will turn into a normal metal block onto which you can jump. From there, climb up to the eye and hit it as much as you can before it hits you.
It's possible, but tricky, to get onto the nose of the cave and attack the eyes from there. After taking one of them out, you can probably pull this off since you will no longer be getting shot at, making it much easier to take care of the second eye.
When both eyes are done, a spark of light will come out of the second one and Data-Sora will collect it with the Keyblade.
After this you get the Debug Abilities, Confusion and D-Blizzard.
Instruction: Defeat the Heartless!
You have four minutes to clear this segment.
A Defender will appear in the middle of the room. It will be deflecting damage blocks as they fall into the room and knocking them towards Data-Sora. Keep him moving while Donald and Goofy attack. Don't forget to keep an eye on their health, and use potions if necessary.
When they beat it, check your results, confirm and continue.
You get the last Crest Piece!
