The Reins of the Cobalt Primordial Direhorn drops from Oondasta on the Isle of Giants in Pandaria on roughly a 0.04% drop rate. Oondasta is one of four mount bosses in the game that can be bonus rolled for an additional chance at the mount each week.
To kill Oondasta you need to make your way to the Isle of Giants. The easiest way to get to it is to take the portal to Jade Forest from the portal room in Stormwind or Orgrimmar.
Oondasta spawns in the center of the Isle of Giants and has a 15 minute respawn timer. Hunters can tame this world boss, so if you see a hunter without a pet nearby you might want to pop your cooldowns in order to Kill Oondasta before the hunter finishes his tame.
Oondasta 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.
As mentioned earlier you can use bonus rolls for an additional chance at this mount. The item you will need to bonus roll Oondasta are Mogu Runes of Fate and you can buy them from Mistweaver Ai.
The currency you need to buy these are Timeless Coins which you can easily farm from Gulp Frogs on the Timeless Isle. You can carry 20 Mogu Runes of Fate at a time and they cost 1000 Timeless Coins each so you will need 20000 Timeless Coins to buy them all. Although you can only use one per week.
Useful addons for Oondasta
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 Oondasta 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.
As Oondasta is on a weekly lockout, defeating it on your alts also each week will give you more attempts at the mount each week.
