Cane of Somaria

The Cane of Somaria, also known as the Staff of Somaria, is a red cane and a main dungeon item that first appears in The Legend of Zelda: A Link to the Past and later in The Legend of Zelda: Oracle of Ages.

With the Cane of Somaria, Link can create a red-orange block. This is required in certain areas without any movable blocks. The Cane of Somaria block is usually required to hold down a floor switch. Unlike regular blocks, Link can move the Cane of Somaria's block an unlimited number of times instead of once. Link can only create one block at a time. If Link uses the Cane of Somaria another time, the block vanishes and instantly appears in front of where Link pointed the cane. Link can get rid of the block altogether by striking it with his sword. Usually if an enemy gets in contact with the block, it gets defeated.

The Legend of Zelda: A Link to the Past
In The Legend of Zelda: A Link to the Past, the Cane of Somaria is obtained in the sixth dungeon, Misery Mire. When Link strikes the Cane of Somaria's block with his sword, it bursts into four fireballs, each of which go into one of the cardinal directions. Some of Link's magic is used each time he uses the Cane of Somaria. In Turtle Rock, the Cane of Somaria has another purpose: it creates a red platform at the starting brown square of a track segment. Link can continue on the platform until reaching the end of the track. If Link reaches a fork in a path, the player can press a corresponding directional button to determine which path he takes.

The Legend of Zelda: Oracle of Ages
In The Legend of Zelda: Oracle of Ages, the Cane of Somaria is the main item of the Crown Dungeon. It no longer shoots fireballs or uses up Link's magic each time that he uses it. It is also necessary to complete the last room of the Hero's Cave via an outside-the-box tactic in a room where Link follows a ghostly Armos.
