Reins of the Thundering Onyx Cloud Serpent

So we all know MoP introduced cloud serpents, but here's one of the more awesome looking ones ( the lightening even makes a sizzling/buzzing noise!)

This mount drops from Huolon on the Timeless isle, which is the island off the coast of The Jade Forest. 

I got extremely lucky with this one, my friend was camping it and asked me if I wanted to join for a couple kills and it just dropped. He is easily soloable at level 100 and as long as you tag him you get loot (personal loot by the way). Its a 1% drop chance so be prepared for a lot of kills and frustration, unless of course you're like me and just get lucky. Again I would recommend installing NPC scan and overlay for this.
