This quest is not available in game.
Bring a sample of Nether-wraith Essence to Gidge Spellweaver in Shattrath's Lower City.
*WARNING!* You can only select one tailoring specialization.
I can teach you the ways of spellfire tailoring if you wish, but be warned, it's a dangerous pursuit.
Creating spellcloth in Netherstorm attracts powerful nether-wraiths. I'm searching for a way to lessen backlash, but I need more nether-wraith essence for my research.
Take this beacon with you to Netherstorm and use it to summon a nether-wraith. Bring back its essence and I'll agree to teach you. As a spellfire tailor, you'll receive twice as much cloth and have access to exclusive patterns.
