Feruchemist

Feruchemistry is a theoretical magical system from the fictional Cosmere universe, primarily featured in Brandon Sanderson's Mistborn series. A Feruchemist is an individual who practices this form of magic. Feruchemists possess the ability to store and tap into their own physical and mental attributes by using metalminds, which are typically made of various metals and alloys. These metalminds are worn or carried by the Feruchemist and are used to store specific attributes when the individual is at their peak, and then later release these attributes when needed.

The process of storing and tapping attributes is governed by specific metals and alloys. For instance, gold is used to store health, while iron is used to store physical strength. Each metalmind must be made of a specific metal to store a specific attribute. The size and type of metalmind can also affect the amount and duration of the stored attribute.

Feruchemists can store a wide range of attributes, including physical abilities like strength, speed, and endurance, as well as mental attributes like memory and knowledge. They can also store emotional states, allowing them to tap into feelings of courage or calm when needed. The use of Feruchemistry requires a great deal of discipline and control, as the attributes stored and released must be carefully managed to avoid negative side effects.

Feruchemists are often seen as wise and knowledgeable individuals due to their ability to store and recall memories and knowledge. They play significant roles in the societies of the Mistborn series, often serving as advisors, scholars, or leaders. The practice of Feruchemistry is deeply rooted in the cultural and religious beliefs of these societies, and the metalminds used by Feruchemists are often considered sacred objects.
