I noticed a couple people were sad that the Confluence soulstones were functional pin worn items. Might be a decent project for someone to come up with a functional soulstone holder type item with variations to be worn in differing slots. Alternately, I wonder if it would be impossible to add this functionality to existing crystal holding jewelry.
