Go grab yourself some noggenfogger elixir and head to blades edge.
Go to the cave near evergrove in blades edge and farm up some costume scraps.
Now fly to the other cave where you use it for a quest and land on top of the cave entrance to avoid agro.
Now dismount and use your noggenfogger and pray for skelleton form.
If you get lucky then use your costume and turn into a drenai.
Now jump on your flying mount and dismiss your drenai costume by either clicking off or flying out of zone.
Now Have a warlock summon you to shatt and have fun showing off.
