Nicrosil is the external enhancement pushing metal. An Allomancer burning nicrosil is able to enhance the effects of another Allomancer's powers. Feruchemists can use nicrosil to store Investiture, and when used as a Hemalurgic spike, nicrosil steals Investiture. While the exact composition of Allomantic or Feruchemical nicrosil is unknown, real-world nicrosil is an alloy primarily of nickel, with some chromium and a small amount of silicon.

Allomantic Use[edit]

A nicrosil Misting is known as a Nicroburst. A Nicroburst burning nicrosil and touching another Allomancer will cause the latter's reserves of the metals that are currently burning to disappear and give a huge burst of power to the recipient.[1] This can cause issues with metals such as tin, where the mental overload can cause unconsciousness.

Feruchemical Use[edit]

A nicrosil Ferring is known as a Soulbearer. Nicrosil is used to store Investiture. This ability is not understood (even by those who utilize it).[1] A Soulbearer storing Investiture stores their ability to use their Investiture. Therefore, a Soulbearer could store their ability to use Feruchemy and another person tapping it would be turned into a temporary Feruchemist who has the ability to fill a metalmind (assuming the nicrosilmind was unsealed).[2] Among other things, a nicrosilmind can be used to store the Divine Breath of the Returned and the ability to use various surges of the Knights Radiant.[3] Filling a nicrosilmind as fast as possible hides a person from an Awakener's life sense.[4]


A nicrosil Compounder would be able to use nicrosil to have a nearly infinite supply of stored Investiture.[5]

Hemalurgic Use[edit]

When used as a Hemalurgic spike, nicrosil steals Investiture.[6]
