They way it will work is as follows: Our raid team will clear the raid up to Hagara including her trash. Once there we will invite you to the raid, summon you there and you will trade us the gold then you may pickpocket the boss. Then you simply hearth out and leave the raid group and go have fun with your quest.
If you are interested or have any questions please contact either myself or Classick via in game mail or whisper. You can also contact us through our forums at Pureraiding.wowstead.com
