Materials

In addition to standard materials and special materials, the following materials are also available:

Orichalcum
Orichalcum is an extremely rare substance, found only on planets with a high concentration of magical energy. It's a special metal like mithral and adamantine, and has extraordinary properties. Orichalcum is difficult to refine because it resists heat (a special process requiring weak acid is used instead). Orichalcum is also exceedingly strong and unusually light.

Orichalcum: HP/inch: 45, Hardness: 25, Weight: 1/2 normal

Weapons: Weapons fashioned from orichalcum have a natural ability to bypass hardness when sundering weapons or attacking objects, ignoring hardness less than 20. Against objects with a hardness of 20 (such as adamantine), the hardness is reduced to 10. Against objects with hardness over 20, there is no change. Against creatures, orichalcum weapons ignore half the DR of the target, as long as it's not epic DR or DR/-.

Armor: Armor made from orichalcum grants its wearer damage reduction of 1/— if it's light armor, 2/— if it's medium armor, and 3/— if it's heavy armor. Orichalcum armor also provides fire resistance 5. Orichalcum items are always masterwork property. Items without metal parts cannot be made from orichalcum.

Prism
Prisms are special crystals that are very strong and dense. The crystals are cloudy white, but shine all the colors of the rainbow when viewed from different angles. They are generally prized for their general hardness and special qualities.

Prism: HP/inch: 30, Hardness: 15, Weight: normal

Weapons: Weapons fashioned from prism count as cold iron for the purpose of overcoming damage reduction.

Armor: Armor and shields fashioned from prism grants its wearer 3 resistance to fire, cold, electricity, and acid. Items without metal parts cannot be made from prism. Items made of prism do not count as metal or wood for the purpose of spells.
