This large and aggressive knight Heartless's skillful defense makes it tough to finish off. Though its focused slash can be stopped with a block, blasting the knight with Thundaga while it is storing up energy will stagger it, opening it up to extra damage, especially from magic.

Strategy
When facing a Dual Blade, it is best the player keep in constant motion to avoid the Heartless's attacks. Block its spinning thrust attack, and jump to avoid the Aerora spells it launches. When the Heartless jumps high into the air, be sure to jump and Glide out of the way, or suffer damage when it comes down and causes a short-ranged shockwave to erupt. A well-timed Dodge Roll can also prevent damamge. When the Dual Blade charges power, immediately Block to avoid the powerful long-range slash attack that follows, as it may inflict the Air-Toss status effect. Blocking this attack successfully will cause the Heartless to collapse, increasing damage that can be done with magic or attacks. As the Dual Blade's journal entry suggests, Thundaga will have the same effect on this Heartless. Once it recovers, the Dual Blade will use the attacks in its arsenal at random. So long as one heals regularly and uses their Limit Break or magic as needed, the Dual Blade should not be much of a challenge.
