Acquire 15 Silithus Venom Samples and 20 gold and bring them along with a set of Devout Bracers to Mokvar in Orgrimmar.
Hail, <class>! I can tell by your demeanor that you've seen and done much in this world. Yet I'm willing to wager you haven't seen a piece of armor like this.
Perform a small favor for me and I'll be willing to trade it to you for an ordinary set of bracers.
I'm in need of a sizeable sample of venom drawn from the spiders and scorpions that inhabit Silithus. Bring this to me along with a few gold coins and I'll perform the exchange.
