Iron is a metal found in Survival 303.
Iron, (in-game referred to as Refined Iron), is the result of Iron Ore being cooked near fire. It is the most common ore, found on Mainland, Rockma, Magma, Plateau, Flax, and Spire. Traders will almost always have this because it is used in so many recipes, such as a Forge, Iron Axe, Iron Sword, Iron Pickaxe, and Iron Armor. Refined Iron is also used in steel, which can be made to level up Smithing fast.
