Iron is a metal in Survival Beginnings.
Iron is the 4th class of tools, stronger than bronze but weaker than steel. It is used to craft steel tools as well as the most powerful alloy in the game, mithril. It is commonly found near to coal, so it is generally advised to skip iron and go straight to steel tools, as a final stepping stone to get mithril.
It is found in the caves of the mainland, big mountain, desert, and cliff island.
