Blueish metal, named after the game it features in; also commonly called 'rune'. In earlier versions of the game and the Old School game, it is the toughest workable metal, [73] and in the main game it is both the strongest workable metal in the free-to-play version, as well as being the main ingredient in the Elder Rune metal.
