For any of you who don't know, a Cloud Serpent is an elongated reptile, most likely of the superfamily Varanoidea, due to their long snake-like body and relatively high intellect compared to other known Azerothian reptiles. Now that you've gotten a brief mental image, let's look at a very beautiful in-game Cloud Serpent, shall we?
The image, while wonderful at showing what a Cloud Serpent is, is quite large indeed. So, here's a simple link.

Ain't it pretty?
Now that you know what it looks like, let's list off the abilities!

Hatchling Vortex
- Channeled for 20 seconds
- 1 minute cooldown
Your Cloud Serpent, almost playfully, spins in a large circle, creating a vortex. Any attackable targets that walk into the vortex are unable to escape it, and will be slowed if they try to walk out and after walking 25 yards, they will be sucked back in.
OR

Breath of The Dragon
- Channeled for 5 seconds
- 50 second cooldown
Your Cloud Serpent breathes an engulfing flame, burning up the armor of any target in front of it and decreasing their armor rating by 12% for 20 seconds.
OR

Rage of The Dragon
- Instant
- 2 minute cooldown
Your Cloud Serpent becomes empowered by the magic of the Vale of Eternal Blossoms, increasing it and your attack speed by 25% for 10 seconds.
And that is my idea for tamable Cloud Serpents. Post any suggestions you have below.

So, feel free to use this, Blizzard.*
