How do you unlock the ability to craft the black metal atgeir?

To unlock the ability to craft the black metal atgeir in Valheim, you must progress through the game''s crafting tiers and gather specific resources. The black metal atgeir is a powerful two-handed polearm weapon that excels in crowd control and high damage output. However, crafting it requires access to black metal, which is only obtainable after defeating Yagluth, the fifth boss, and exploring the Plains biome.\n\nFirst, you need to defeat Yagluth, the Fuling boss, to unlock the ability to smelt black metal. Yagluth is found in the Plains biome, and summoning him requires placing five Fuling totems at his altar. These totems are dropped by Fuling shamans, brutes, and regular Fulings in the Plains. Once Yagluth is defeated, you gain access to the Artisan Table, which is essential for crafting advanced items like the black metal atgeir.\n\nNext, you must gather black metal scraps, which are dropped by Fulings in the Plains biome. Fulings are aggressive humanoid enemies that patrol the area, so be prepared for combat. Equip strong armor, such as padded armor, and bring a reliable weapon like a silver sword or frostner to handle these foes. Black metal scraps are not smelted directly; instead, they are refined into black metal bars at the blast furnace, which requires unlocking the Artisan Table.\n\nTo build a blast furnace, you need 20 fine wood, 10 iron, 4 chains, and 5 surtling cores. Fine wood is obtained from birch and oak trees in the Meadows or Plains biomes. Iron is mined from muddy scrap piles in the Swamp biome, and chains are found in chests in the Swamp or dropped by Wraiths. Surtling cores are collected from burial chambers in the Black Forest or by killing Surtlings in the Ashlands biome. Once you have the blast furnace, place it near your forge and smelt black metal scraps into bars.\n\nAfter obtaining black metal bars, you need to craft the black metal atgeir at the forge. The recipe requires 10 black metal bars, 10 fine wood, and 5 linen thread. Fine wood is gathered as mentioned earlier, and linen thread is crafted from flax, which grows in the Plains biome. Flax can only be harvested after defeating Yagluth, as Fuling villages often have flax plants. Use a cultivator to plant and grow flax in your base, then process it into linen thread at the spinning wheel.\n\nOnce you have all the materials, head to your forge and craft the black metal atgeir. This weapon is excellent for dealing with groups of enemies due to its wide sweeping attack. It also has a secondary attack that staggers enemies, making it useful for crowd control. However, it consumes a lot of stamina, so manage your stamina carefully during combat.\n\nA common challenge players face is surviving in the Plains biome while gathering black metal scraps. To mitigate this, bring healing meads, stamina meads, and poison resistance meads. Additionally, avoid engaging large groups of Fulings at once; use terrain to your advantage and pick off enemies one by one. Building a small outpost near the Plains biome can also help you store resources and recover quickly.\n\nIn summary, unlocking the black metal atgeir requires defeating Yagluth, gathering black metal scraps from Fulings, refining them into bars, and crafting the weapon at the forge. Focus on preparing for the Plains biome by upgrading your gear and stocking up on essential supplies. With the black metal atgeir, you''ll have a powerful weapon to tackle even the toughest enemies in Valheim.
