Allomancers are sorcerers whose spark of magic caused them to be able to burn metals and alloys to fuel their magical abilities. The magical ability granted to an allomancer depends on the metal or alloy used. Each metal has an alloy as a pair; this pair represents two sides of an ability - a push and a pull. There are four pairs of base metals and four pairs of higher metals; there is one pair of godly metals and a single metal that can awaken allomantic powers in others.

The base metal pairs can be divided into physical and mental metals. Physical metal pairs are steel/iron and pewter/tin. Mental metal pairs are bronze/copper and brass/zinc. Steel allows an allomancer to push on other forms of external metal. Iron allows an allomancer to pull on other forms of external metal. Magically enhanced metal, buried metals, and metals surrounded by living tissues are less effective. Bronze allows an allomancer to see other allomancers and occasionally see other magic auras. Copper allows an allomancer to hide the alomancy or magical auras around themselves. Brass allows an allomancer to soothe emotions, taking a specific emotion away. Zinc allows an allomancer to inflame emotions, giving a specific emotion more power.

The higher metal pairs can be divided into temporal and enhancement abilities. Temporal metal pairs are electrum/gold and bendalloy/cadmium. Enhancement metal pairs are duralumin/aluminum and nicrosil/chromium. Electrum allows an allomancer to see ghosts of their own future, effectively seeing their own future options. Gold allows an allomancer to see ghosts of their own past, versions of themselves that could have been. Bendalloy allows an allomancer to create a fast time bubble around themselves. Cadmium allows an allomancer to create a slow time bubble around themselves. Duralumin allows an allomancer to burn their metals in one flare, increasing the output of the flared metal. Aluminum allows an allomancer to destroy their own metal reserves. Nicrosil allows an allomancer to burn metals of others in one flare. Chromium allows an allomancer to destroy the metal reserves of others.

The godly metal pair is atium/malatium. Atium allows an allomancer to glimpse into the future of those around the allomancer. Malatium allows an allomancer to glimpse into the past of those around the allomancer. Lerasium is a metal that, when ingested, gives the person allomantic abilities.

If you are lighter than it, you fly away from the metal, landing a distance away, relative to its weight difference (a maximum of 10 feet away). If you have moved, roll an atheletics or acrobatics check. You land on a successful save. On a failed save, you are prone.
