Start a new game as a character that has the items you want. Find a good 
secret place such as in the water or way out in a field (preferably near 
a landmark, like a really tall tree, and remember the COORDINATES!!!)
Dump all your items, clothes, and spells. Then play as your favorite 
character and get all of it, and sell it. You won't be able to lose 
anything, but try to put it where others won't find it!
