Eliminate the Dual Blade.
Roxas tackles the Dual Blade in Halloween Town.
Before accepting the mission, equip a lot of Thunder magic to deal with the boss in a more effective manner. If you want to speed the process up, come back later with Thundara and Thundaga magic. Move to the right of the starting point and jump to grab the Unity Badge. Then follow the path straight defeating Heartless and unlocking a chest to obtain a Gust Shard. Once you reach the town square, the Dual Blade will instantly charge at you. Either defeat the Dual Blade, then search the area for treasures or vice-versa. Glide over top of the well to obtain the Ordeal Badge, then continue straight to reach the Ordeal Blazon. To the right of the Ordeal Blazon (hidden behind the wall) you will find a chest containing an Aerial Recovery LV+ Ⓛ. After you have cleared the area, its time to RTC.

Being timely with your blocks against the Dual Blade's focused blade attack creates additional opportunities to strike. Generate as many extra openings as possible, because you can't wait to attack between attacks!
|Challenge Mission 54SP|
Avoid taking damage!
|Level capped at 10|
Deal 30% less damage
|3||1 or less|
|2||2 to 5 hits|
|1||6 to 10 hits|
More a test of patience than anything else, this challenge determines if you're willing to wait to attack between its attacks, only to inflict minimal damage. Hit the Dual Blade with Thunder and Thundara spells to provide extra chances to attack. Otherwise, jump and Dodge Roll out of the path of its thrust and attack conservatively, with only two or three hits per combo.
