First, make sure you have one of the two:
- Savory Deviate Delight [Fish]
- Orb of Deception [Orb]
Next, get ahold of some Hallows End Candy. This can be done by flying, for alliance, to Southshore, or for Horde to Tauren Mill. You should see a yellow ! for someone in the middle of the city.
If anyone wants to name the quests for the horde, go ahead. But for alliance the quests (and how to do them) are;
1. Crashing the Wickerman Festival (56,70)
Alot easier to do if you're a higher level, around 55-60. May take you a few deaths if you're not. Go west from UC and you will see some Haystacks. Ride through the middle (watch for the guards!) and it will say quest complete. The reward is 15 candies.
2. The Power of Pine
This one requires Horde to help you. You must be atleast level 25. Horde have the quest to place Stinkbombs inside Southshore, and you must destroy one of them by spraying them (you get the sprayer with the quest). The reward is 15 candies.
So, once you have your candies and the Orb/Fish, eat them until you get the skeleton one. Then pop either the Orb or the Fish, use your mount, and right click the Orb/Fish buff off.
You must be on your mount first, and you must eat the candy before the orb/fish.
Now run around IF and get 50 whispers a minute asking how this was done! This can also be used with noggenfogger skeleton and Orb/Fish combo.
