A mana loom is an world object that was needed once in time to craft a [Bolt of Imbued Netherweave] cloth. It is no longer required as of patch 3.0.2.
The mana looms have still not been removed from the game and can be found at the following locations:
- Shattrath City: There are two located in the market area of Lower City. The first is positioned between the three Tailoring Specialist trainers, Nasmara Moonsong, Gidge Spellweaver and Eiin [66, 68]. There second is located near Eral, the General Goods vendor [62, 70]. Watch out, the vendor vomits when someone completes [25-30] Of Thistleheads and Eggs..., which can interrupt your crafting.
- Silvermoon City: In the Bazaar, at the Tailoring shop. [56, 50]
