WOW Gold: Click the button in the lower left area of the refine window to start the process
The process of enhancing is simple, and requires nothing more then luck. You pick one of the 8 boxes for the Elrue/Lix/Xir and drag and drop it in. If you have more WOW Gold than one Elrue, you may need to separate one into a separate pile of its own.
To do so, hold the “Left Shift” key and click on the Elrue, and set “Item Allocation” to “1”, press OK, and click in an empty inventory square. Alternatively, you can simply allow the default number generated in the “Item Allocation” box, press OK, and click in an empty inventory space and achieve the same results.
After you have one Elrue ready, click the button in the lower left area of the refine window to start the process. The enhancing is successful if the spinning star lands on the box opposite of where you placed your Elrue/Lix/Xir.
If it was successful then it will gain +1. If it doesn’t land there, then 1 of 3 things will happen. Your item will remain the same, your item will decrease a level of enhancement, or your item may be destroyed. This is the basics of enhancing.
If you click the button and your item disappears, it has been destroyed. Some say the more you break the more luck you have on the enhancing skills. [Unconfirmed]
