Make Used Relics Say (Used) After Item Name
I think it's obvious that people are scamming and lying about their relics or simply forgetting they used it and sell it off to people as if they hadn't, to them the relics are the exact same price and everything as if they were unused. I think it would help out the game a lot if we could tell which ones were actually used already just by looking at the names of them. I just got a couple relics and threw them in with all of my unused relics and now I have no idea which ones the problems are. It'd help out a ton.
