Hello everybody :wave:
This exploit will give you 22.000 xp and near 13g every ~4 minutes! ( As stated in the title -.^ )
Well, let's get on with this.
First of all kill withered trolls outside of "The Ebon Watch" to get the unliving choker and begin this quest chain - An Invitation, of Sorts... - Quest - World of Warcraft
Work through the chain until you get to the quest - Infiltrating Voltarus - Quest - World of Warcraft
Here is where the actual exploit begins. When you accept the quest, you are given Stefan's Horn, which allows you to summon Stefan to you at any given point.
Use the Enscrolled choker and take the portal up to Voltarus, and take Drakuru's task - Reunited - Quest - World of Warcraft
Run to the direct opposite side of Voltarus and take the tour, which takes around 3:40 minutes. When you land, run over to Drakuru and turn in the quest - Reunited - Quest - World of Warcraft
This is very important, because if you mess this up it ruins any opportunity for the repeatable quest in the future. Take the portal back down to the ground below Voltarus and use Stefan's Horn, and while Stefan is flying down abandon the original quest - Infiltrating Voltarus - Quest - World of Warcraft
When Stefan lands, he will allow you to re-pick up - Infiltrating Voltarus, and you can re-zone into Voltarus and get the quest Reunited - Quest - World of Warcraft once more, repeating these instructions above infinitely. If done correctly (takes a moron to mess it up), you will have an average yield of 200g per hour or 314250xp.
Hope this will be of benefit for you all.
That's all for me, hope you like it!
