The Goron Mask is one of four Masks used for Transformation,the other three being the Deku Mask, the Zora Mask, and the Fierce Deity's Mask. When worn, it transforms Link into a Goron. The Mask contains the spirit of the fallen Goron hero Darmani III, and when Link dons the Mask, he inhabits the warrior's body. The transformation grants all the special abilities of that species, including a new fighting style, the ability to carry Powder Kegs, a special Goron Pound attack, and the ability to roll at high speed while attacking with spikes, which consumes Magic Power.

In Snowhead, the ghost of the Goron warrior Darmani lingers in Goron Village, waiting to be healed. Link can speak to him if he equips the Lens of Truth. After overcoming the initial shock that Link can see him, he asks him to follow him to his grave in the Goron Graveyard. Darmani then relates the tale of how he died, but says he cannot rest and wishes to have his sorrows healed. Link can play the "Song of Healing" to heal his soul, which is then encased in the Goron Mask.
