It is posted screen shots following the process
When you have the costume wands you cant use them on your self so you need them from someone ells. What if you could do it alone with only your own chars on same account. Well this is how you do it
I have a warrior mage and a druid for this setup, i get a friend to inv all my chars into one raid. The char i want to complete this with is the mage, so what i do it go to the innkeeper and do the trick or treat thingy. If your lucky you can get a costume wand you need on your achivement char(the mage here)
you open 2 wow clients get both chars to stand in same place dosent mather where it is. So i want the costume on my mage and i got the wand on my warrior. They are all on the same account, i log into my mage and when im rdy i quickly logg inn on the warrior with my second client. WHen im in my mage will still be online and infront of me so i use the wand on him and you turn your character into what the wand was ment to.
Cant provide screenshots as i just did it 60 min cd you know. If repost soz, just trying to give somthing back to the forums. =)'
