Elemental obelisks can be used to charge unpowered orbs into elemental orbs which can be attached to battlestaves to make fire, water, earth or air battlestaves. To charge an unpowered orb, it must be taken to the obelisk of the element that the player wishes to have the orb charged to as well as the required runes to charge the orb. There is an obelisk of air, obelisk of earth, obelisk of water, and an obelisk of fire. The obelisk of earth is in the Edgeville Dungeon, with the obelisk of air above it, and the obelisks of fire and water are in the Taverley Dungeon.
