allow someone to fix a broken slot on an item by taking another of said item and "grafting" a fresh slot from one article to the other exchanging the broken slot for a good one, this would keep rare clothes rare but allow those of us that want to wear different **** to achieve a good level of slotting on our rare pieces.
currently once a slot or two is broken the piece you were working on is ****, thus preventing someone from ever trying to slot the harder items into a set of gear.
