Obelisk of Air

The Air obelisk is located in level 9 wilderness, and can be reached by climbing the ladder north of the Black demons in Edgeville Dungeon. It is used for enchanting an unpowered orb into an air orb (requires level 66 magic), which gives 76 magic experience. At level 66 crafting, an air orb can be attached to a battlestaff to make an air battlestaff, granting 137.5 crafting experience.

As the Air Obelisk is in the Wilderness, extreme caution should be taken when visiting it, as player killing happens in the wilderness, and an unprepared charger can end up losing their orbs and runes. Bringing teleport items such as an Amulet of glory or runes may be wise, although one still has to be careful, since players with a high magic level may teleblock you.
