Regular Mission
Eliminate the Windstorms.

Story summary
Roxas must eliminate three Windstorms.

Mission walkthrough
Before starting the mission, be sure to equip lots of healing items, Hi-Ethers and Thunder spells. You will have to face not only three Heartless bosses at once, but also an Invisible.

Head to the Halloween Town Square to take on three Windstorms at once and a host of Detonators. Don't waste your Thunder spells on the Detonators! Thunder spells can not only stun but also cause extra damage to the Windstorms. Your mission is completed once you have finished off the three, but you can continue to the Graveyard to encounter an Invisible. It watches over a Hi-Potion and a Shining Crystal in nearby chests.

Challenge Mission
Thunder magic will speed the battle way up. Equip a magic-boosting weapon, such as Crown of Guilt++, with all slots filled with Magic Unit Ⓛ, and link up as many casts of Thundaga LV5 as you can. Bring along Hi-Ethers or Elixirs if you don't have enough casts. Cast Thundaga on the Windstorms as quickly as possible. To give you an extra edge, also equip movement abilities like Haste, Air Slide, and Glide.

For this Special Challenge, bring along many casts of Thundaga, as well as magic-restoring items. Keep your distance from the targets, using your map to keep track of their locations. Avoid close combat to reduce the risk of getting hit.
