Strategy
At the start of the battle, Lock-On to the Tail Mirage as it hovers above you. As this is an aerial battle, you must jump to the Heartless' level before you can begin your attack. Use caution, as the Boss will eventually proceed to summon homing balls of blue energy to damage you. From this point forward, the Heartless will warp around the battlefield, making attacks difficult to land.

You must also be careful not to get too close to the Tail Mirage, as it will stab you with its talons in an attempt to knock you away. Another attack in this Heartless Boss' arsenal involves it spiraling into you, dealing impact damage. The Tail Mirage will also flip in the air, damaging those in its way. So long as you heal periodically, utilize your Limit Break, and attack whenever possible while at the same time dodge the beast's attacks to the best of your ability, you should be able to tackle the Tail Mirage in a matter of minutes. If you wish to use Magic in this battle, use the when the Heartless is stationary. Attempt a spell while the beast warps to a new location, and your spell is guaranteed to miss.
