Obtaining: The Cobalt War Talbuk is purchased from a vendor (Trader Narasu for Alliance and Provisioner Nasela for Horde) after reaching exalted status with the Kurenai and the Mag’har factions respectively.
1) This reputation grind is the same for both factions. It is just one big and simple mob grind. The reputation is gained by killing a number of creatures found in Nagrand, Outland, but the best way to go about it is by killing all ogres you can find in the areas marked on the map below.
The ogres respawn reasonably quickly, so you can pick a couple of spots and fly between them. This reputation grind can be completed in one sitting but will require a few hours.
2) Make sure to loot all ogres as they drop Obsidian Warbeads 10 of which can be turned in for an extra 500 reputation.
Alliance players turn in warbeads to Warden Moi’bff Jill.
Horde players turn in warbeads to Warden Bullrok.
3) Once you reach exalted status, you can buy the mount.
Alliance players buy the mount from Trader Narasu, who is located in the same village as the turn-in NPC.
Horde players buy the mount from Provisioner Nasela, who is also located in the same village as the turn-in NPC.
Extra Tips: Humans receive 10% extra reputation from all sources due to their racial buff. Additionally, countless reputation buffs can be utilized to speed up your reputation gains further, such as the Darkmoon Faire Buff (DMF is around for one week every month), WOW Anniversary buff or other mini-holiday related buffs such as Hollow’s End one.
