i'd be careful attempting this when moving on to the aftergame bf. i used the item duplication method Raze mentioned in another post on these forums to bring them to the aftergame bf's just for kicks, and then was experimenting with ways to use them for shortening trips to and from dungeons &/or merchants. the result of bringing something somewhere it was not meant to be was a broken quest log, making almost all future bf quests unresolvable. basically only the first one on the list could still be solved, but the subsequent ones on the list weren't static, and would toggle quest goal/item and quest giver, changing them, every time you clicked the "jump to recent flagged quest button (the little push pin)", making them unresolvable . thankfully i still had a previous save as i had the foresight to create one before experimenting.
also, if you are thinking about using this method to give yourself the pyramids, don't bother unless you want nifty useless trinkets to display in your rift-realm-room-chamber-area-place-location-thingy.
they don't work. but it is a good way to duplicate cash, charms, crystals, and alchemy plants. i wouldn't advise messing with weapons & armor, BF keys (especially not those), or the crystal bag (strange things happen to your resistances, and the crystals that are in the bag, that i really don't feel like going into here).
EDIT
almost forgot the best duplication use: holy water. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> .:heh:.
