Completing this achievement involves looking around the instance and looting various Jade Quilen, usually located behind trash or in hard to reach places, in a similar manner to the Extra Credit Bonus Stage achievement from Vortex Pinnacle during Cataclysm.
The locations of the Quilen you need to loot are;
- hidden at the very end of the first room, behind the trash
- next to Kual the Brute in the first boss room
- hidden in an alcove on right, after going down the hidden steps from the first boss but before the first Glimtrok Scout
- around to the left or right side of the balcony before Gekkan
- in either of the two rooms immediately before the last boss, click the Orb to break down the Jade Statue and it should be there
In addition, if you have a hunter in the group, there is a Jade Quilen which spawns inside one of the vaults, which can be tracked. This vault can be opened without needing an Ancient Mogu Key.
