Iron Ore

Iron Ore is found from the surface level and deeper, and appears as a slightly brownish grey ore. It creates Iron Bars, which can be used to make tools and armor, as well as Iron Chains, Buckets, and other useful items. It's also a material for Ironskin Potion

Because Iron Bars are used to create Anvils, a player usually must obtain some iron before any armor at all can be forged. Although it is possible to buy an Anvil for 50 silver coins from the Merchant instead, this use of money is typically inefficient.
