This mod adds a variety of stuff as copper tools and armor which effect the gameplay beacause you the player has a new way to protect yourself because of how copper is more found in caves and its armor and tools durability is lower then iron but equal in the protection and other stuff and also amethyst tools and armor that has less durability then diamand tools but are sharper and bc of how they are made out of amethyst taht means that they get a fire boost and am still adding more stuff as a music disc and more in the next versions until the full release
