Cold Iron is a rare form of iron left over from the creation of Ordd. It has never been molten and will loose its properties and become normal iron if melted or tempered. This makes it very hard to work for the following reasons:

  • Care must be taken not to heat the metal too much, lest it loose its special properties.
  • The finished product must be hammered from a single piece of ore, as it cannot be smelted.
  • Being a tough metal, it is hard to work. Usually, a smith will ruin one or more set of tools working a single piece of cold iron.

Cold Iron ore is worth its weight in gold, and forging cold iron is a long and difficult process adding 100 gp per pound to the price of the base item.


A metal weapon, made with Cold Iron, will cause an extra 1d4 damage to fey, undead, and fiends it it hits them. It also counts as a magic weapon against these creatures for purposes of immunity and resistance. Magic Weapons that are made of cold iron function as normal magic weapons, loosing the cold iron ability unless they are in an anti-magic field.

The Holy Avenger and the Warblade of Azel are both made from cold iron.


A piece of armor incorporating Cold Iron gives the wearer (or wielder in case of a shield) advantage on spells and spell-like abilities cast by Fey, Undead, and Fiends. In addition, if attacked by these types of creatures that make contact with the wearer (i.e. bite, slam, touch, etc.), the attacker takes 1d4 damage (as if from a magic weapon). Only metal armor (and studded leather) and metal shields may be guilt or edged in cold iron.

Cold Iron Barriers

Fey, Undead, and Fiends have difficulty passing a barrier of Cold Iron. To do so, they must first pass a Constitution check of DC 15. This is why some graveyards have cold iron chains surrounding them, to prevent the dead from rising as undead and leaving the graveyard.
