Runite bar

Runite bars are used in the Smithing skill to smith various runite weaponry and armour. At level 85 Smithing, players can smelt a runite bar by using runite ore and 8 pieces of coal with a furnace, granting 50 Smithing experience for smelting and 75 Smithing experience for smithing.

Three of them can be obtained occasionally when opening the crystal chest.
