Elegy of Emptiness

The Elegy of Emptiness is taught by the King of Ikana in Majora's Mask after Link defeats him. This song leaves an exact replica of the form Link is in at the time, but it can only make one of each form. This song is required to scale up the Stone Tower, and it's also necessary to solve several puzzles inside the Stone Tower Temple. A total of four replicas can exist at any given time, one of each of Link's forms. The Deku form is the least used, however, as it is too light to be of any use. It is important to note that the replicas can only be formed if Link is in any of the areas pertaining to Ikana Canyon, for if the song is played anywhere else, it won't have any effect.
