So what's the deal? What's the change? How do I obtain it? What enchant is it?
The Gnomish Coin ( me ) did a post about this enchant becoming best in slot for cloaks recently that pretty much sums it up pretty good.
The Enchant & Change
The enchant is Enchant: Cloak Stealth. The enchant got changed from it's old form of simply providing extra stealth for rogues and feral druids, to 8 agility and 8 dodge rating. This now makes it one of the best enchants for the cloak slot if you're leveling.
The materials for this enchant are fairly cheap, making the profit margins extremely high. I can currently craft them for under 20g per enchant, and they sell for 200g+. I suggest you begin stockpiling the materials for this enchant NOW as later down the road, prices will most likely inflate. This is your only shot to grab these materials for cheap before they inflate, go do it!
How do I obtain the enchant?
The Enchant is obtained by two means. One is either by getting exalted with the Cenarion Expedition, or you can run AQ 20/40 and pray for a drop ( it won't ). Either way, I suggest you go get this enchant as soon as possible and start crafting them NOW, before prices on the materials inflate and the profit margins drop.
