An unpowered orb is an item used to make enchanted orbs by casting an enchanting spell on the corresponding obelisk, then crafting the orb onto a battlestaff to make an air, earth, fire, or water battlestaff. An unpowered orb can be made out of molten glass by clicking on said glass at Crafting level 46, granting 52.5 Crafting experience.
Creating unpowered orbs can be a cost-effective way to train Crafting. Including banking time, a full inventory of molten glass takes about 58 seconds to craft. Using this method can therefore yield over 90,000 experience per hour with monetary gain of 2.11 coins per experience gained, assuming Grand Exchange market prices.
Unpowered orbs can sometimes be found inside barrels, and are also a common item received while pickpocketing Cadarn workers.
