Collect all the Jade Quilen located throughout Mogu’Shan Palace on Heroic Difficulty.

I found these maps over at wowdb. The 2nd lion is found after the smoke clears. For the 3rd jump on the brazier while spam clicking/selecting it may take a bit.

As far as the the last two.  If you do this alone after every one leaves and you didn’t do a full clear there is some trash left. The trash near the vualt is easy peasy. The very last on though may be a bit challenging.

Here’s the tip i found over at wowdb:

The fifth one is in a room off to the side on the way to the final boss, Xin the Weaponmaster.  The room is off to the left side.  Inside will be some trash, and three dog statues.  Use the scrying orb after defeating the trash.  It will destroy the largest dog statue and the final Quilen will be underneath it.
