Tin
Tin is the internal physical pulling metal. An Allomancer burning tin has greatly enhanced senses. Feruchemists can use tin to store enhanced senses, and when used as a Hemalurgic spike, tin steals senses.
Allomantic Use
A tin Misting is known as a Tineye. Burning tin grants an Allomancer increased sensitivity in all five senses.[1] Furthermore, they are able to see through the mists that cover Scadrial.[2] An Allomancer can flare tin, causing a huge burst of sensory input, to clear his head from pain or exhaustion.[3] Tin will allow an Allomancer to see in the dark.[4]
Feruchemical Use
A tin Ferring is known as a Windwhisper. Tin is used to store sensitivity of senses. One sense may be stored each in a tinmind.[1] Unlike an Allomancer burning tin, it does not allow a Feruchemist to see things that would be otherwise unobservable; instead, it compounds the potency of their senses currently available.[5] While storing senses, those senses become weaker. For example, Sazed wore glasses while storing eyesight.[6]
Hemalurgic Use
When used as a Hemalurgic spike, tin can steal senses.
