Khorium Ore

Khorium Ore is mined from Khorium veins found in most regions of Outland. A mining skill of 375 or better is required to extract ore from a Khorium Vein.

Khorium Veins are a rare spawn of Fel Iron or Adamantite Deposits, much like Truesilver is a rare spawn of Mithril and Thorium. It can be found in any zone where those metals can be found. The ore is easily distinguished by its strikingly purple color and bizarre emanating waves of energy.

Khorium Veins have most often been reported in Nagrand and Zangarmarsh, but have been reported in all other regions of Outland and the Isle of Quel'Danas.
