In Dragon Age: Inquisition, runes can be applied to weapons that possess a rune slot to improve the effectiveness of the weapon. Runes are applied at the "Modify Weapon" table in Haven or Skyhold's Undercroft. Runes cannot be applied to armor. Once applied, a rune cannot be removed, only replaced. Runes can be found or crafted by the Inquisitor once the schematic has been obtained. Runes can also be purchased from merchants and awarded for completing quests or war table operations.
