Cloud Serpent Taming
Pandaren hunters automatically know how to tame Cloud Serpents. Hunters of other races must learn the skill from the tome How to School Your Serpent, which may purchased from San Redscale at The Arboretum in The Jade Forest. You require Exalted standing with The Order of the Cloud Serpent to read this tome, but the learned skill is account-wide.
Friendly. Appears during Mogu Assaults. The Ivory Cloud Serpent spawns every ~1.5 - 2.5 hours at coordinates ~ 27,55, at roughly 2-3 times the height of the trees, and flies rapidly in clockwise circuits around the zone.
