Feruchemy is an end-neutral manifestation of Investiture that allows the user to convert certain attributes into Investiture and store them in metal that they are in physical contact with, and to later retrieve them from the metal. Although it is generally inherited or obtained through Hemalurgy, there are other ways to become a Feruchemist,{{wob ref|12776}} involving the Scadrian [[God Metal]]s, [[atium]] and [[lerasium]].{{wob ref|14146}} As an end-neutral art, Investiture is not gained from an outside source (as it is in end-positive arts) and Investiture is not permanently lost (as it is in end-negative arts).{{book ref|mb4|part=ars}} Ordinarily, when a Feruchemist is tapping an attribute at the same rate it was stored, they are able to get out exactly what they put in, for example, if they store 50% of their strength for one hour they can tap that and be at 150% of their strength for one hour. However, if the Feruchemist taps at a greater rate, then some of the attribute is lost, to facilitate the compression of the Investiture. This means that a Feruchemist who stores 50% of their strength for one hour might only be able to stay at 200% for 25 minutes, rather than a full half-hour. The more a Feruchemist compresses the attribute, the more is lost.{{wob ref|6126}} While a Feruchemist can only store attributes at a reasonable rate, there isn't anyan upper limit of how much they are able to tap at any given time.

Feruchemists who [[Compounding|Compound]] their metals for extended periods of time may be physiologically altered by the constant influx of power. Since Feruchemy doesn't draw from an external power, it is very difficult to become a [[savant]] from just using normal Feruchemy.{{wob ref|13463}} If the Feruchemist is able to Compound and draw power from an outside source they could become a savant much more easily.{{epigraph ref|mb3|32}}{{wob ref|13393}}
