From The Gamer: “In the world of Valheim, you’re only as good as your best resource. Iron isn’t an item that comes easily, but once you figure out how to keep a steady supply of metal coming, you’ll be well into Valheim’s mid-game. There’s a lot you’ll need to accomplish before Iron becomes accessible, but if you’re venturing into some of the game’s most dangerous biomes, you may want to keep your eyes peeled for this highly desirable material. If you’re having a hard time nailing it down, here’s everything you need to know about iron: where to find it, what it’s used for, and how to get it.”
