Heavenly Golden Cloud Serpent

I assume this mount looks like Tsulong during his day phase...Doesn't seem to be available yet though.

Edit: New information on this mount can be found here [item=87774]. My original post was from back before the actual mount item existed and all we had was the data mined mount spell.

I recently obtained this mount on live so allow me to answer some questions I've been getting.

Where did you get it, how much does it cost, and what are the requirements?
You can buy this mount from [npc=73306] (42,54) for 100,000 [currency=777]s after achieving exalted rep with Emperor Shaohao. Mistweaver Ku can be found to the right of Emperor Shaohao, the pandaren floating on the pedestal near the Celestials, if you're facing his backside.

Where did you farm?
There are 3 main spots to farm for rep if you do not have the legendary cloak; the Firewalker Ruins, The Blazing Way, and just outside of the Ordon Sanctuary. Without the cloak, you can get to the plateau either by hopping on a two-person mount with someone who does and jump over, taking a [npc=73531] and dropping down, jump off the bridge and be mass resurrected, and other creative ways like flying to the isle and using a glider such as [item=104346].

If you do have the cloak, then I recommend farming inside the Ordon Sanctuary itself as there is usually less competition.

You will get an abundance of coins on your journey to exalted from drops alone with plenty to spare. Doing the quests and dailies rewards an upwards of 1,000 coins or more and occasionally a tiny bit of reputation.

How did you get it so fast?
It is best to have a group of 5 and no more. You'll receive no coins in a raid group and reputation will diminish after 5 players. A composition of a tank/healer/3 dps works well enough, but it is most efficient if you can find 5 dps that can avoid the major attacks completely, use self heals/cooldowns, and just burn 1-2 mobs at a time.

How long did it take?
I did two 7-8 hour sessions over two days and went from Neutral to Exalted at a rate of 2,100 rep per hour, give or take. I had the guild [spell=78635] perk and used my [item=64399] whenever I could for another 15%. The rate at which you receive reputation will greatly depend on the competition and how quickly you can move from one mob to the next which is why I recommend 5 high damage dealers.

I hit the 100k coins mark shortly after reaching Revered.

I hope someone found this information helpful. Goodluck and happy farming. (:

This is a beautiful mount, it's a shame (and ironic) that the one place you can't show it off is where you spent the time and effort obtaining it.
