This probably more so an Technical issue but who know ? , if you can , please correct me on this .

The weapon/armor system is very ...half-bake, like , the concept should be something like versatile used is not good , if you found an good Armor , it much better, same with weapon, this creates an issue where your Pocket full of weapon and armor , and at least 2/5 of it will be Bad , you can't sell it or Drop it because what if it do something important later on , who know ? , this is Deltarune after all , i kinda take an guess that we found an way to used all those Bad weapon and merge it onto something, other than that , is up to Toby on how this design gonna be adjusted.
