The Crumble Bundle

Big thing to keep in mind if you're abandoning quests and re-trying... You need to wait until the 10 minutes from the first timer is up to restart. Didn't realize that and beat it within 8 minutes thinking I was a badass... and I didn't get credit. fml

To get this achievement you have to recover and deliver all four missing statue parts to the remnants of the Chamberlain statue at 34.6, 64.8 within 10 minutes of accepting The Crumbled Chamberlain. Parts can be found in the subregions of the Isle of Thunder below:

• 
  
• Za'Tual
• 
  
• Court of Bones
• 
  
• Ihgaluk Crag
• 
  
• The Beast pens / Conqueror's Terrace
• 
  

Patch 5.2 Hotfix: March 21
Crumbled Chamberlain: Statue pieces now do not despawn when looted, allowing other players to loot the statue piece as well.

First of all, the biggest issue is encountering the masses who zerg the whole isle all day long. You pick up the quest, trying to find a part and someone took it before you could. Good to know the parts are continuously respawning randomly on one of the possible locations in each subregions so you're free to move around and search for another one.

There is at least one possible spawn point for the quest-giver object in each area that means you can start the quest wherever you want.
Each area has a fixed part of Chamberlain (Torso, Hair, Staff, Shoulder) so you cannot skip a subregion. Every subregion has plenty of spawn points for their own parts. (the number of spawn points are still growing on the PTR). The spawn point of the object (within an area) will be randomly selected each day.

For a head start, it is worthy to note that you should deliver the quest (within the 10min window) to the mutilated statue of Chamberlain in the Court of Bones area so if you're running out of time over and over again you can save some time by planning a good route which ends up at the Court. Progression could be tricky, success depends on a bunch of things and may take several attempts due to high variety of possible spawn points / combinations.

Tips:
- Use the /timer command; start it as soon as you pick up the quest.
- Saurok giga-jumps help a lot in the Ihgaluk Crag area just spam it until the statue part blinks up on your minimap.
- Court of Bones and Conqueror's Terrace are flooded with crabby enemies, just try to avoid unseat from mount.
- Stay in the Mogu runes at the Court you get a nice buff that speeds up the killing job. Otherwise do not mess with enemies you really don't have to. Dodge them, skip them, leash them and move on.
- Engineering comes really handy.
- If you missed few seconds and/or delivered the quest too late/by mistake, don't go suicide: The Crumbled Chamberlain is a weekly quest.

Here's my video about how to get the achievement, you may also find some more tips and infos about locations, etc:

Easiest way to do this, and I have tested this on live after Stage 3 opened, is to accept the quest, find the other pieces, abandon the quest and complete it knowing the spawn locations. People mentioned that the spawn points changed, but this didn't occur for me. No when looted, and not when the quest was abandoned. Simply scout the spawns, drop the quest, and then pick it back up again.
