Vilhelm: How to locate iron
Iron is what makes you a strong character in Valheim. It takes time before you can gain access to iron. This is because you will not have iron available in the first regions (Shire Forest and the Black Forest).
First, you must beat the boss you defeated (The Old One) to unlock its key.
With the key , you can head to the swamp and access the crypts that are often.
In the crypts, you can mine iron (in the form of scrap iron). Make sure to bring your pickaxe.
Every crypt can be returned home with a full bag. Then, you proceed as usual by using the smelting oven, which converts ferrous scraps into ingots of iron. In the process, you’ll gain access to new items like iron armor, the hunter’s bow, and other powerful tools and weapons. When you’re equipped, you’ll be able to slowly travel into the mountains to look for silver, as it’s the next level.
