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, 30 air runes and 3 cosmic runes), 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. Bring 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.
Enchanting orbs into air orbs is a good way of making money while training magic; earning up to 250,000 gp and 40,000 experience an hour.
The most efficient way of enchanting large numbers of air orbs is to run to the obelisk from Edgeville Bank and teleport back using a charged Amulet of glory, allowing fast banking and thus faster training.
The Air Obelisk area is a PvP zone after the return of free trade and the old wilderness.1
