Magnesis

is a Rune ability in. The Rune allows Link to lift and carry metallic objects using magnetic energy.

Location and Uses
The Magnesis Rune is obtained in the Oman Au Shrine at the Great Plateau. The Magnesis Rune allows Link to harness magnetic energy to lift and carry metallic objects into the air effortlessly, which can then be moved and placed elsewhere. When the Rune is activated, red grid lines cover Link's immediate surroundings. Objects in that area that can be picked up will have a red filter, and will turn yellow as the Rune's cursor moves over them, signifying that they can be selected. Once lifted, Link can manipulate the object either by moving it in the air, dropping it, or pushing or pulling it. This can also be used to hurt enemies through various methods, such as dropping heavy metal boxes on top of them.

Metallic NaN Treasure Chests can be picked up using the Magnesis Rune—this can be used to move Treasure Chests that are normally out of Link's reach.

In, Magnesis is used as a combat ability used by all Warriors. Located on the R Button wheel along with its sibling Runes and tied to the B Button while holding R, Magnesis can be used in a variety of ways.

When it is prompted, Magnesis is used to counter a monster (mainly a giant Bokoblin or Moblin) or a human enemy like Master Kohga throwing a metallic (enough) weapon by grabbing it with magnetic energy and sending it right back at them to damage/expose their Weak Point Gauge, stunning them in the process. Alternatively, Magnesis can be used by picking up metal crates to make them be used as improvised weapons. Any weapons that is picked up by Magnesis is merely for effect.

Magnesis is also needed to pull up the hidden partially buried Treasure Chests scattered across the Chapter Scenarios.

Once Magnesis is used in a combat manner, it puts the entire R Button wheel on a cooldown for every playable Warrior that is on the field, so the cooldown cannot be circumvented by switching characters. Completing the "Shocking Fear" Quest lowers the cooldown after using Magnesis.

As Zelda's first weapon class is Sheikah Slates, Magnesis is incorporated into her moveset. As it still counts as Magnesis without using the actual Magnesis prompt by using the R Button, Zelda's first two Strong II Combo strings can be used in place of a Magnesis counter.

Nomenclature
The word magnesis is a contraction/portmanteau of the word "magnetism", which comes from the Ancient Greek magnítis líthos (μαγνήτης λίθος) which means "lodestone from the region of Magnesia", and "kinesis" (κίνησις, kínisis), which is Ancient Greek for "motion".
