What happens to the items and gold found while powerleveling?
Good items will be used to improve your character, everything else is sold to merchant or on Auction House. Some of the gold will be used to purchase skills and needed equipment, the remaining gold will stay on your character when the leveling is done. Since levelings (depending on server, class, gameplay) are not always done in the same manner with the same results, we are unable to make any specific statements regarding exactly how much gold will be on the account after the leveling.
