The Reins of the Heavenly Onyx Cloud Serpent drops from Sha of Anger in Kun-Lai Summit and has around 0.03% drop rate, so be prepared to kill this boss for a long time. It is one four mount bosses that can be bonus rolled.
To easily get to Pandaria take the portal to Jade Forest in the portal room in either Stormwind or Orgrimmar.
Sha of Anger spawns next to One Keg and every 10-20 minutes so it is not a long wait but it does die fast so make sure you are alert. As for killing Sha of Anger it is as simple as just sit there and tag it when it spawns.
Sha of Anger is a world boss on a weekly lockout, so you are only able to kill it once per week per character. Once defeated the loot will automatically be awarded to you, no need to loot.
Additional Tips
Bonus Rolls
As mentioned earlier you can use bonus rolls for an additional chance at this mount. The item you will need to bonus roll Sha of Anger are Elder Charm of Good Fortune and you can buy them from Commander Lo Ping in Townlong Stepps.
The currency you need to buy these are Lesser Charms of Good Fortune which you can easily farm from Gulp Frogs on the Timeless Isle. You can carry 20 Elder Charms of Good Fortune at a time and they cost 20 Lesser Charms of Good Fortune each so you will need 400 Lesser Charms of Good Fortune to buy them all. Although you can only use one per week.
Useful addons for Sha of Anger
There are three I would recommend:
Rarity – Rarity is a good addon to have for any mount farms, it keeps tabs on how many tries you have on the mount.
Worldboss Timers – This is another really great addon as it is a timer for all of the world bosses in case you plan on killing Sha of Anger on multiple characters on the same server
Saved Instances – This addon will keep track of which characters have completed raids, world bosses and various other things. Great for knowing which characters you can still attempt the worldboss with.
Misc
As Sha of Anger is on a weekly lockout, defeating it on your alts also each week will give you more attempts at the mount each week.
