Yes, I know there's an exact replica in the Nagrand Ring of Blood. However, if you've already done the quest and didn't keep or choose the replica, now is your chance to pick up this exquisite staff.
Please send bids to me either in this thread or through in-game mail. I am willing to also post this item on the Neutral AH for any Alliance peoples that want to bid as well. I will keep entertaining bids for a week (or until I'm happy with a bid).
Good luck, and thank you for your time.
