Goddess Wall

Goddess Walls are sacred murals in SS undefined that are used to generate various items.

Location and Uses
Goddess Walls are invisible at first, and can only be found by playing the Goddess Harp near a wall where three Blessed Butterflies are congregating. Once revealed, the Goddess Wall appears as an ornately carved indigo rectangle, with the Goddess Crest in its center.

After charging a Skyward Strike, Link is able to draw on the Goddess Wall with his Sword. Depending on the shape Link draws, the Goddess Wall will release a different reward. Once used, a Goddess Wall goes inactive until restarting the game.

After obtaining Farore's Courage, Gorko will ask Link to draw shapes on a Goddess Wall in the Sealed Grounds. If Link does this successfully, he will be rewarded with a Piece of Heart. Once he draws all the shapes, he will receive a Gold Rupee. In all other cases, Gorko will give Link a Red Rupee or a Treasure.
