Black Uruk steel ingots are an alloy used to make Black Uruk armour and equipment.
Black Uruk steel is made by alloying Morgul iron ore or Orc steel with Durnor in an Orc forge. Morgul iron ore is found underground in Mordor, Dol Guldur and Angmar, and Durnor is found only in Mordor.
To save fuel for smelting, it is recommended to use Morgul iron ore rather than Orc steel ingots in creating this alloy.
These ingots can also be dropped by Black Uruks rarely, or produced by unsmelting unneeded items made from this type of steel.
Upon smelting a Black Uruk Steel Ingot, the player earns the achievement "Black Smithery"
As with other ingots, Black Uruk steel can be crafted into a mineral block for compact storage or decorative purposes.
