Bring 1 Qiraji Regal Drape, 2 Obsidian Idols, 5 Clay Scarabs and 5 Gold Scarabs to Keyl Swiftclaw in Silithus. You must also obtain Revered reputation with Cenarion Circle to complete this quest.
I'm glad to hear you're aiding us in our attack on Ahn'Qiraj, <name>. I can make you a protective item that'll be of assistance in the fight against our enemy, <class>.
I shall need a Qiraji drape, which I'll resize for you of course. I'll also need idols and scarabs which I'll use to create a suitable clasp.
I promise you won't be disappointed.
