Bugged. It does not do what it is intended and instead the buff just drops once your disguise is broken.

This item still doesn't have a page on live wowhead.com. It exists, although it still doesn't seem to work. The buff just stays there, but you don't make any clones or get stealthed.

Still purchasable, still does not appear to work. Buff is maintained when cover is broken... it just doesn't do anything.

It is easy to get 远古魔力 if you know where. So far the best spot is in Suramar City.

HERE IS THE BEST ROUTE!
