Which biome should you prioritize for quick iron acquisition in speedruns?

In Valheim speedruns, prioritizing the Swamp biome for quick iron acquisition is essential due to its abundance of Scrap Iron, a critical resource for mid-game progression. The Swamp biome is the only location where you can find Muddy Scrap Piles, which yield Scrap Iron when mined with an Antler Pickaxe or better. This biome is also home to Sunken Crypts, which are dungeon-like structures filled with Muddy Scrap Piles and other valuable loot. However, the Swamp is a dangerous biome, so preparation is key to success.\n\nBefore venturing into the Swamp, ensure you have the proper gear and tools. Craft a Bronze Pickaxe or upgrade to an Antler Pickaxe if you haven''t already. Equip yourself with a Finewood Bow and Flinthead Arrows for ranged combat, as the Swamp is filled with hostile creatures like Draugr, Leeches, and Blobs. Additionally, bring Poison Resistance Mead, as many enemies in the Swamp deal poison damage. Crafting a Karve or Longship is also recommended for efficient travel, as the Swamp is often surrounded by water.\n\nOnce you arrive in the Swamp, focus on locating Sunken Crypts. These structures are easily identifiable by their green torches and iron gates. Inside, you''ll find Muddy Scrap Piles, which require a pickaxe to mine. Be prepared for combat, as Crypts are populated by Draugr and Skeletons. Clear enemies systematically to avoid being overwhelmed. Each Muddy Scrap Pile yields 5-10 Scrap Iron, making Crypts the most efficient source of iron in the game.\n\nA common challenge in the Swamp is dealing with the constant threat of poison and stamina drain. To mitigate this, always carry Poison Resistance Mead and Stamina-boosting foods like Carrot Soup or Queen''s Jam. Additionally, avoid standing in water for extended periods, as Leeches can quickly drain your health. If you encounter an Abomination, a large tree-like enemy, use fire arrows or a Flint Axe to exploit its weakness to fire.\n\nAfter gathering enough Scrap Iron, return to your base to smelt it into Iron using a Smelter. Iron is used to craft powerful tools, weapons, and armor, such as the Iron Pickaxe, Iron Mace, and Iron Armor. These upgrades are crucial for tackling harder biomes like the Mountains and Plains. Prioritize crafting an Iron Pickaxe first, as it allows you to mine Silver in the Mountains, further accelerating your progression.\n\nFor speedrunners, efficiency is key. Plan your route to minimize backtracking and maximize resource collection. Use portals to quickly return to your base for smelting and crafting. If you''re playing with a team, divide tasks to cover more ground and clear Crypts faster. Remember, the Swamp is a high-risk, high-reward biome, so always stay alert and prepared.\n\nIn summary, the Swamp biome is the best choice for quick iron acquisition in Valheim speedruns. Focus on locating Sunken Crypts, prepare for combat and environmental hazards, and prioritize crafting essential iron tools and weapons. With proper planning and execution, you can efficiently gather the iron needed to dominate the mid-game and beyond.
