Brass
Brass is the external mental pushing metal. An Allomancer burning brass is able to dampen the emotions of those around him. It can be targeted at a single person or a group. Feruchemists can use brass to store warmth, and when used as a Hemalurgic spike, brass steals mental Feruchemy.
Allomantic Use
A brass Misting is known as a Soother. Emotional Allomancy is not mind control, but it does allow the practitioner to influence the emotions of those around him. The effects can be targeted a specific individual or group, and can focus on specific emotions.[1] Soothing emotions can be used to decrease someone's fatigue, fear, or happiness. It can accomplish many of the same things as Rioting emotions (via an Allomancer burning zinc) by soothing all but the specified emotions.
Feruchemical Use
A brass Ferring is known as a Firesoul. Brass is used to store warmth. While filling a brassmind, a Feruchemist will be cool.[2]
Hemalurgic Use
When used as a Hemalurgic spike, brass steals mental Feruchemical powers.
