Runeforging is a skill specific to death knights, involving the affixing of runes to the death knight's weapon. It requires a runeforge, which can be found in four places: The upper chamber of Acherus: The Ebon Hold in the Eastern Plaguelands, the Shadow Vault in northern Icecrown, the fortress structure at Mord'rethar: The Death Gate in southeastern Icecrown, and Darion Mograine's runeforge at Light's Hammer in Icecrown Citadel. After a small quest chain, the Shadow Vault—inhabited by hostile Scourge—can be captured to serve as a questing hub for the Knights of the Ebon Blade, allowing ease of access to the Vault's runeforges.
To engrave a rune on a weapon, open your spellbook to your specialization's tab and click on the Runeforging icon. You'll see a list of Runes that you know. Choose a rune, then click the Engrave button. Your mouse pointer turns blue—use it to click on the weapon you want engraved. It helps to already have your character profile or bags open.
Runeforge enchantments count as permanent, and they overwrite any regular enchantments such as Enchant Weapon - Mongoose or Enchant Weapon - Executioner. Runeforge enchantments can also be placed on Bind-to-account weapons, such as . Runes are always better than weapon enchantments.
Runeforging requires that the weapon have an item level of 45 or higher (except for BoA items), since any weapon a death knight would encounter will be higher than this. Prior to Patch 4.0.3, attempting to apply a rune to an heirloom weapon would result in an error about the item level being too low.
As of Patch 7.0.3, there are three different runes that can be affixed to your weapon. Two are for both one- and two-handed weapons, and one is for two-handed weapons only. The runes affixed to a weapon can be changed by additional runeforging, but weapons can have only one rune at a time. In general, the best runes are Stoneskin Gargoyle for Blood, Fallen Crusader on main hand and Razorice on offhand for Frost, and Fallen Crusader for Unholy.
