Cane of Somaria

The Cane of Somaria is a reoccurring item in the Zelda series, and first debuted in A Link to the Past. This red cane, when used, instantly creates a single block that Link can push and sometimes can be carried around. Only a single block can be created at a time.

A Link to the Past
In A Link to the Past, the Cane of Somaria is the treasure item of Misery Mire. In this title, magic is needed to create blocks and its blocks can be detonated. The Cane of Somaria is mostly used in the Turtle Rock dungeon.

Oracle of Ages
In Oracle of Ages, the Cane of Somaria plays a very similar role, although without the use of magic power as in its A Link to the Past counterpart. It is the primary treasure of Level 5, Crown Dungeon. Unlike A Link to the Past, the block created can not be detonated.

Four Swords Adventures
In Four Swords Adventures, the Cane of Somaria makes a reappearance. Like many tools in this title, it can only be carried by an empty handed Link and would have to swap their current tool to use another, and could only be acquired and used in certain areas.

Trivia
In its first appearance, the Cane of Somaria required magic to work, but in its second it did not, most likely because a Magic Meter does not exist in the Oracle Series.
