The August Celestials

You are in REMIX, late for the party and trying to find out how to max these folks?
Here's how to farm this faction from Neutral to Exalted for 1-2 days with minimum efforts involving mild RNG:

You need to farm this rare which is on exactly 20minute respawn timer. It drops Stolen Celestial Insignia. To be precise, it might drop the item, but it might drop other bonus rep items. I've had multiple consecutive kills without a drop fo the bonus rep item, but then again I've had two times drop 4x the item from a single kill. Good ole RNG.

Great news is that you can do this farm by combining it with other REMIX farms (except LFR content).
Go to the boat in the Isle of Giants, wait for it, kill it, start your chronometer (to count 20min from the moment it died) then use Nostwins-Voucher.
You can then spend 19 minutes doing other Remix stuff and then use the voucher once again to return to the boat, right where you departed from after killing the rare, after 19 minutes has passed and the rare is about to respawn.
If you use LFR and enter a group - you will lose the 1-hr buff that allows you to tp back to where you used the item from. The way to tp is by using the special ability button that pops in the middle of your screen.

I hope this helps you! Good luck on your adventures!

I'm not getting the 10x boost for dailies from this faction. Are we doing this ~1000/rep per day or is there a shortcut?

I have the commendation and I am still not getting the boost. Got it for golden lotus but not for August Celestials
