Dark Iron OreFollow

To create one Dark Iron Bar, you need 8 Dark Iron Ore, and you can only smelt Dark Iron at the Dark Forge, which is located near the portal to Molten Core. Before you can smelt it, you need to learn how to smelt Dark Iron Ore from Gloom'rel deep in Blackrock Depths in the 7 Ghosts room. He'll teach you how to smelt it if you give him 20 Gold Bars, 10 Truesilver Bars, and 2 Star Rubies. You can only make items that require Dark Iron Bars at the Black Anvil, which is on the other side of the instance where Lord Incendius is located.
