Cold Iron

The poison of whimsy and chaos alike.

This iron, mined deep underground and known for its effectiveness against demons and fey creatures, is forged at a lower temperature to preserve its delicate properties.
Weapons, armor, ammunition, and other equipment made of cold iron require an additional +2,000 gp to be made magical. This increase is applied the first time the item is enhanced, not once per ability added.
A double weapon with one cold iron half only costs 50% more than normal. Weapons not primarily made of metal weigh twice as much if made from cold iron. Armor without metal parts cannot be made from cold iron. Full plate could be made of cold iron, but leather armor cannot be.

Properties

Material Characteristics

Incredibly difficult to distinguish from regular iron, the only real way to tell is both from it's temperature and seemingly being more reflective then regular iron.

Physical & Chemical Properties

The primary property of cold iron that makes it differ from normal iron, is its ability to suppress or surpass the defenses and magical powers of fey and demons alike. Making it an incredibly useful material to have when dealing with either. However, the same properties that allow it to do this, also makes initially enchanting such a material more difficult to do.
Additionally, cold iron often resides at a lower temperature then normal iron, seemingly less capable of absorbing heat.

Geology & Geography

Only found deep underground, deeper than where most underground dwelling creatures come to reside, cold iron is common in expeditions into the deep down are taken, though there are dangers involved with exploring locations in the deep down, such as remaining forces from the dark war.
