Crimsiron

Crimsiron, also known as Blood Steel, is a type of metal mined deep beneath The Burning Rise. It is forged using a combination of both Arcane Craft and the traditional forge method. It is famous for its ease of enchantment, and durability and if used enough could absorb the blood of those struck down by blades made of Crimsiron and make the wielder a furious combatant.   Some sources also state some resistance to divination could be achieved by wearing armour made from Crimsiron.  

Cost

Crimsiron weapons and armour cost four times as much as their standard counterparts, and enchanting them costs an extra 1000 gold pieces.  

Sources

The Town of Xynnar within the Borders Abercast is a major source of Crimsiron to the world of Sanctuary.
