Mission 84: Eliminate the Scorching Sphere

Mission 84 in Kingdom Hearts 358/2 Days sends Roxas and Xigbar to the Olympus Coliseum where they must defeat a Scorching Sphere.

Mission goal
Defeat the Scorching Sphere.

Story summary
Roxas and Xigbar are sent to eliminate a Scorching Sphere that has appeared in Olympus Coliseum.

Mission walkthrough
This is a fairly straightforward mission, as Roxas can enter the Coliseum without needing to talk to Phil. The Scorching Sphere is bigger than the Morning Star, and can inflict the Ignite status if you're hit, making this mission more difficult. Like the Morning Star, it will start to spin around as soon as it appears, but if you're fast enough, you can Glide up to it and cast a Blizzard spell, which will stop it in its tracks. It uses the exact same tactics as the Morning Star, so dodging it and retaliating should be simple. Using Blizzard magic, especially Blizzara, will help deal more damage. Xigbar is a very helpful ally on this mission, as he will occasionally cast Blizzard spells to further damage the Sphere.

Once defeated, collect any chests that remain and RTC.

Challenge Mission
Bringing Blizzard and Blizzara spells will help clear this mission. Glide up to the Scorching Sphere and quickly cast Blizzard to keep it from running around, then strike it with Blizzara spells. The Darker than Dark+ Keyblade is highly recommended, as it greatly increases magic power.
