Deep dark curses

I feel there should be a block that adds curses to an item at the cost of some sort of new currency maybe even shadow shards. I think it shouldn't be able to remove curses from an item just to make it balanced or it can I think it works fine either way but I think this would be expecially usefully for things you want to keep on your when you die like maps soul compasses ECT. I don't care if this doesn't get added to the game I thought it would just be a cool new block or something I'm only 10 so I probably have no clue what I'm talking about
