- "Manipulate metallic objects using magnetism. Grab on to metallic objects using the magnetic energy that pours forth from the Magnesis Rune. Objects held in the magnetic snare can be lifted up and moved freely."
- — In-game description
The Magnesis Rune is an item from The Legend of Zelda: Breath of the Wild. It is a Rune ability for the Sheikah Slate allowing Link to move metallic objects. These objects can be used to damage enemies, move obstacles, and form bridges. It can also be used to dig up buried Treasure Chest and identify Treasure Octoroks pretending to be buried treasure chests as their chests are non-metallic. It can also be used to pick up metal weapons which can be useful for obtaining metal weapons that are underwater such as the Ceremonial Trident in Zora's Domain.
Link can lift metal objects such as crates, metal blocks, and metal gates to drop them on enemies damage them. Dropping metal crates from a high height will cause them and any crates struck to break. Some hidden Koroks can be revealed by using Magnesis to move a small metal cubes to complete geometric puzzles found in the environment.
The word magnesis refers to magnetism and comes from the Greek magnetis lithos (μαγνήτης λίθος) which means "lodestone from the region of Magnesia".
