Zinc is the external mental pulling metal. An Allomancer burning zinc is able to inflame the emotions of those around him. It can be targeted at a single person or a group. Feruchemists can use zinc to store mental speed. When used as a Hemalurgic spike, zinc steals emotional fortitude.
A zinc Misting is known as a Rioter, or Zinc Counselor. 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 to a specific individual or group and can focus on specific emotions. Rioting emotions can be used to increase someone's desire, determination, or anger. It can accomplish many of the same things as Soothing emotions by rioting all but the specified emotions. Extreme emotions in the target will interfere with emotional allomancy. Emotional allomancy can affect animals, however it requires a certain amount of sapience.
Allrianne Cett is a known Rioter.
After the Catacendre, it is unlawful for a business to use Rioters to influence customers. This was one of the provisions of the Allomantic Agreement of '94. There is evidence of consensual emotional counselling.
A zinc Ferring is known as a Sparker. Zinc is used to store mental speed. It allows the Feruchemist to think very quickly and come to conclusions faster. While filling a zincmind, the Feruchemist will be dull-witted and slow. Storing does not affect the Feruchemist's ability to process physical information, such as being able to hear when they are spoken to.
