Collecting More than 111 of Sora’s Selves
It is possible to raise your maximum HP upon arriving in the Final World by collecting more than 111 of Sora’s “selves.” Doing so can increase your HP limit by up to 10.
The area is accessible during the final battle at the Keyblade Graveyard.
While this is not particularly a useful upgrade to your maximum health, it is an interesting mechanic added to the game.
Collecting up to 222 of Sora’s selves raises your total HP by 5. You will gain another increase of 5 by gathering 333 of the Soras wandering in the area. Your HP cannot be raised further using this method afterwards.
Tips for Collecting Sora’s Selves
Several cubes can be found in the Final World. When struck, they will change the orientation of the area, allowing you to more easily reach Sora’s selves wandering around.
