Magic System – Allomancy

Allomancy is a hereditary magical power allowing users to ingest and “burn” metals inside their bodies to gain supernatural abilities.

Allomancers must swallow small metal flakes suspended in alcohol or water and metabolize them to activate their powers.

There are two types of Allomancers:

Mistings

Can burn one specific metal.

Most common type of Allomancer.

Mistborn

Extremely rare individuals capable of burning all metals.

Considered incredibly powerful and dangerous.

---

Basic Allomantic Metals

Physical Metals

Iron Pulls nearby metal objects toward the user.

Steel Pushes metal objects away from the user. Skilled Allomancers use this to launch themselves through the air or across rooftops.

Mental Metals

Zinc Riots emotions, making feelings stronger.

Brass Soothes emotions, calming or suppressing emotional reactions.

Temporal Metals

Gold Shows alternate versions of the user based on different life choices.

Atium Allows the user to see the immediate future movements of others, making them nearly impossible to defeat in combat.

Enhancement Metals

Aluminum Instantly removes all metal reserves from the body.

Duralumin Greatly enhances the next metal burned, releasing a massive burst of power.

Allomancers must carefully manage their metal reserves.
