Karma Scissors, zHelms, FM?

I think 1-of-a-kind items just refuse being picked up or traded if you already have one. You can receive them other ways (eg. if a quest gives you one) and end up with 2 or more in your inventory.


You could experiment with the 4th job pre-quest items (torn note from Crimson Balrog etc.) as most of those are tradeable and 1-of-a-kind.



What I think would probably work is (for example) put your 29 dex Helm in storage, then loot new ones to scroll. If nothing comes of it you could just take the Helm back out of storage..
