Iron is an uncommon shiny material made from Iron ore. Iron ore is found in larger caves and hidden outcrops. It cannot be mined with a stone pickaxe.
Iron is used for the majority of mid-game and end-game items, including but not limited to weapons and armor superior to bronze, anvils, and most importantly, steel. Iron bars are created with one iron crafted near a furnace.
Iron has low trade value due to being relatively underused.
