Can be tamed.
|Wowhead:||Vakkiz the Windrager|
Located in Terokkar Forest. Can be spawned through the quest Adversarial Blood in Skettis. When he's first summoned, Vakkiz appears as a living wind serpent (with a different ID) who cannot be tamed. He transforms into his tameable, undead form half way through the fight. Unlocking this quest requires completing most of the Skettis quest chain and farming for a number of summoning items. See the quest link for detailed information.
