Synch Blade



Synch Blade is an ability which allows a Keyblade wielder to summon another Keyblade during battle. So far, the only characters to use this are Roxas, who can use this ability to summon his two Keyblades, the Oathkeeper and Oblivion, and Sora while in Valor Form, Master Form, and Final Form.

Sora has the ability to use Synch Blade because of his inheritance of Ventus's heart, which means he holds the heart of a second Keyblade wielder within his own. This appears to be inherited from Roxas, as it was not present in Sora's abilities until Roxas returned to Sora in the prologue of Kingdom Hearts II. To date, Sora has not been able to use Synch Blade outside of his Drive Forms, however this may be a possibility as he shares his abilities with Roxas who was able to do this.

Kingdom Hearts II and Kingdom Hearts II Final Mix

 * Roxas learns Synch Blade immediately before fighting Axel in the Basement Hall. The ability cannot be used after the fight ends.
 * Valor Form has Synch Blade as a default ability.
 * Master Form has Synch Blade as a default ability.
 * Final Form has Synch Blade as a default ability.

Kingdom Hearts 358/2 Days
While Synch Blade is not an ability in its own right, Roxas can wield two Keyblades in Story Mode on Day 358, and in Mission Mode by equipping Zero Gear with three Ability Units.

Trivia

 * Though it is not considered an ability, Sora gains the opportunity to wield his own Keyblade as well as both of Roxas's in the Roxas boss battle in Kingdom Hearts II Final Mix, if the "Duel Stance" Reaction Command is completed successfully.
