Final Form

Final Form is a Drive Form that unleashes the Keyblade's true power which appears in Kingdom Hearts II. It uses both of Sora's party members, and consumes five of Sora's Drive Bars. It represents Sora's completion, and can be unlocked after Sora and Roxas come to terms at the Dive to the Heart. Its emblem is a white wave.

Mechanics
Although Final Form is unlocked after fighting Roxas, it is not added to the Drive menu right away. It first activates randomly when trying to Drive into another Form, after which it can be used like any other Form. Final Form gains 1 experience point for every Nobody defeated (including Organization members). Leveling up Final Form will give Sora the ability to use Glide while in Standard Form.

Final Form gives Sora the ability to wield two Keyblades, and enhances his ability to perform magic spells by combining them with physical attacks. Every action in Final Form is accompanied by attacks from the Keyblades floating at Sora's sides, even jumping and gliding.

Strategy
Final Form turns Sora into a living weapon; simply making contact with enemies while gliding or jumping does damage. Final Form is useful against all enemies, because Sora's power, speed, and magic are all dramatically increased. Like Wisdom Form, Sora glides along the ground rather than running, and becomes able to perform commands while moving. His casting is sped up and all his magic finishers increase in power and area of effect as well. The player should always be prepared to cast Curaga, as there are no party members to help.

Since Final Form levels by defeating Nobodies, it is best to avoid using it while fighting Heartless and Pirates. The player should try to defeat enemies as fast as possible by mixing up standard attacks with magic. The best Keyblades for training Final Form are the Bond of Flame, Fatal Crest, and Fenrir, as these have high stats in at least one section. The Ultima Weapon's MP Hastega is very useful, as is Oathkeeper's Form Boost. The best worlds to train at are Twilight Town, especially at Yen Sid's tower, and The World That Never Was (in the castle), as they have Nobodies to fight rather than Heartless. Go to Proof of Existence and head for Naught's Skyway. Skip the small way to the upper Hall of Empty Melodies and go to where there are many Creepers. Change into Final Form and defeat all of them, then head back to Proof of Existence and go to the world map. Repeat as desired.
