Obelisk of Fire

The Fire obelisk is used to cast the Charge Fire Orb spell; the spell must be cast on the obelisk, not on the orb in the player's inventory. It is used for enchanting an Unpowered orb into a fire orb (requires level 63 magic), which gives 73 magic experience. At level 62 crafting, a Fire orb can be attached to a Battlestaff to make a Fire battlestaff, granting 125 crafting experience. The Fire Obelisk is located in Taverley Dungeon near the Black dragons.
