As I was helping some friends quest, we did the quest Tree's Company - Quest - World of Warcraft
By the way, this little exploit is Alliance only. I assume many Humans/Nelfs/etc. haven't done this quest before. So this would be awesome!
So basically, you get the quest from the chain The Prophecy of Velen - Quest - World of Warcraft
Soo... now you must want proof. Well here it is:
That's proof that its on my mount.
And thats proof that its portable. We are at the questgiver in this picture atm.
Have fun doing stuff with this.
Soo how can you have fun with this? Easy. Get summoned to Ironforge or Stormwind and then have the person with the mount run around with you on top of it. Wee.
