I am a notorious hoarder too but even I sold all my Slimecrust blades, Slimek leggins and Cryptblades.
Like, what do you want to do with them? Even if you wanted one, it's super easy to just get a new one. They are not rare.
+You can hoard a whole lot of money if you sell all the junk which is much cooler in my opinion and actually useful to hoard. Once all this shattered world stuff is over, my li'l guy will be a rich millionair from selling all the junk items and live in a giant mansion.
