The Besaid Key is needed in order to open a chest containing the Search Sphere. The Besaid Key can be obtained via two different ways: * Buying it in the shop at Besaid Village for 900,000 gil in Chapters One and Two. * Rescuing its owner in the Cavern of the Stolen Fayth in Chapter Three. After obtaining the Besaid Key the player should head to Temple at Besaid to the chamber with the locked chest. Using the key will open the chest and the Search Sphere will be received.
