Mithril

Mithril is one of the two hardest metals in the known world. It is only found deep within the earth, and as such is most commonly mined and bought to the surface by the skilled craftsmen of the Dwarves. Mithril is far lighter than its durability would suggest, and as such is highly valued by the Elves in making elegant yet deadly weapons. Only Dwarven and Elven smiths have ever been known to create items from Mithril of any considerable worth, as it can take many decades to master its use. Mithril has the following innate properties; An item made of Mithril grants a +5 Skill bonus to any ritual cast to enchant it due to the metal’s magical affinity. In addition, a ritual cast on an item made of Mithril can never suffer a catastrophic failure.
