GMs can use the Writing Quill on an item (any item, doesn't have to be parchment) then type:~~copy
Well, sure, that might work, but you have to admit it would be much more fun to spawn a bunch of goblins and kill them all to reap your items. You could even make it a game and have the PC work for the item."Just kill this balor here and you can have your cloned item."
