Came across a nice little gem today. I was visiting the reagent vendor in SW, Kyra Boucher. I was selling my junk, and saw that she now sells Gateway Control Stone for 7g. So everyone that is a non warlock can enjoy these benefits, but if you are a warlock, this may open a glyph spot if you are currently using the Glyph of Gateway Attunement.
Wowhead says that this item is not available to players, although i just bought it, so I believe that it is an error.
PS: Anyone know how I can make my links do the hover over display of the item? thanks
