Shackled Ur’zul Info:
Shackeld Ur’zul is basically created from dead bodies and tormented souls of Army of the Light warriors.
It’s an account-wide flying mount that allows flying in Legion once you unlock it.
Mount has a 100% drop chance from Mythic difficulty of the Antorus the Burning Throne raid. The boss is Argus Enslaved.
The appearance of the mount is rather questionable, but a true collector can’t miss it, because the model is unique.
To obtain Shackled Ur’zul for lesser money, buy Antorus Mythic loot run. You will get a discount in that case.
