Underpay imo, a full meta set plus a magnetic rod just for a clean mino chestpiece does not seem worth at all for me, if it were good enchant definitely or if you add 1 or 2 more pieces.
Overpay imo, a full meta set plus a magnetic rod just for a clean mino chestplate is a great deal, if it were good enchant or if you added 1 or 2 more pieces you’d be scamming yourself.
Full meta set (including amulets) > clean mino chest so its not an overpay. So hes underpaying actually.
Furthermore theres people who would gladly overpay with 1 boss drop per meta gear piece so why would anyone take this trade
