Phantom Sphere
Phantom Spheres are an item given to Link from Ciela in Phantom Hourglass that allow Link to temporarily freeze time using the Phantom Blade. Ciela gives them in your two last boss battles and with them you can stop the time for a several seconds. During the final fights, you must trace the hourglass symbol on the touch screen. During the final battle, you must time it right when Bellum opens his eye.
