How do you unlock the ability to craft iron weapons and tools?

To unlock the ability to craft iron weapons and tools in Valheim, you must first progress through the game''s early stages and gather the necessary resources. Iron is a mid-tier material that requires exploration of the Swamp biome, defeating specific enemies, and upgrading your crafting stations. Here''s a detailed step-by-step guide to help you unlock and craft iron gear.\n\nFirst, you need to defeat the second boss, The Elder, located in the Black Forest biome. The Elder drops a Swamp Key, which is essential for accessing Sunken Crypts in the Swamp biome. These crypts contain Muddy Scrap Piles, which yield Scrap Iron when mined with a Bronze Pickaxe or better. Without the Swamp Key, you cannot progress to the next stage of iron acquisition.\n\nOnce you have the Swamp Key, head to the Swamp biome. Swamps are dangerous areas filled with enemies like Draugr, Leeches, and Blobs, so ensure you are well-prepared with upgraded Bronze or Troll Armor, a strong weapon, and plenty of healing items like Cooked Meat or Honey. Locate a Sunken Crypt, which is a dungeon-like structure with green torches outside. Use the Swamp Key to unlock the entrance.\n\nInside the Sunken Crypt, you will find Muddy Scrap Piles blocking your path. These piles require a Bronze Pickaxe or better to mine. Each pile yields Scrap Iron, which is the raw material needed to craft iron gear. Be cautious of enemies like Draugr and Skeletons inside the crypts. Clear them out before mining to avoid interruptions. Once you have gathered enough Scrap Iron, return to your base.\n\nNext, you need to smelt the Scrap Iron into Iron using a Smelter. If you don''t already have a Smelter, you can craft one using 20 Stone and 5 Surtling Cores. Place the Scrap Iron into the Smelter along with Coal to produce Iron Bars. Each Scrap Iron yields one Iron Bar, so gather as much as you can to craft multiple items.\n\nTo craft iron weapons and tools, you must upgrade your Forge to level 2. This requires building a Forge Cooler, which costs 25 Fine Wood and 10 Copper. Fine Wood is obtained by chopping down Birch or Oak trees in the Meadows or Black Forest biomes. Once the Forge is upgraded, you can craft iron tools like the Iron Pickaxe, Iron Axe, and Iron Mace, as well as weapons like the Iron Sword and Iron Atgeir.\n\nA common challenge players face is surviving the Swamp biome. To mitigate this, bring Poison Resistance Mead, crafted at a Fermenter using Honey, Thistle, Neck Tail, and Coal. This mead reduces poison damage from enemies like Leeches and Blobs. Additionally, use a shield to block attacks and a bow to deal with enemies from a distance.\n\nIn summary, unlocking iron crafting involves defeating The Elder, exploring Sunken Crypts in the Swamp biome, mining Scrap Iron, smelting it into Iron Bars, and upgrading your Forge. Prepare thoroughly for the Swamp biome''s dangers, and gather as much Scrap Iron as possible to craft a variety of powerful tools and weapons. With iron gear, you''ll be ready to tackle tougher biomes like the Mountains and Plains.\n\nPractical Tip: Always carry a portal with you when exploring the Swamp biome. This allows you to quickly return to your base to repair tools, drop off resources, or recover if you die. Portals are invaluable for reducing travel time and minimizing risk during dangerous expeditions.
