How do you unlock and use the black forge for black metal upgrades?

Unlocking and using the Black Forge in Valheim is essential for crafting and upgrading high-tier gear, particularly black metal items. The Black Forge is a late-game crafting station that allows you to work with black metal, a resource obtained from the Plains biome. To unlock and use the Black Forge, you must first progress through the game, defeat key bosses, and gather specific materials.\n\nTo begin, you must defeat Moder, the fourth boss located in the Mountains biome. Moder drops Dragon Tears, a critical item required to craft the Artisan Table. The Artisan Table is a prerequisite for building the Black Forge. Once you have Dragon Tears, craft the Artisan Table using 10 Wood, 2 Dragon Tears, and 4 Iron. Place the Artisan Table in your base to unlock advanced crafting options, including the Black Forge.\n\nNext, gather the materials needed to build the Black Forge. You will need 10 Fine Wood, 20 Iron, 5 Chain, and 5 Surtling Cores. Fine Wood is obtained by chopping down birch or oak trees in the Meadows or Black Forest biomes. Iron is mined from Muddy Scrap Piles in the Swamp biome, and Chains are dropped by Wraiths in the Swamp or found in Sunken Crypts. Surtling Cores are commonly found in Burial Chambers in the Black Forest or dropped by Surtlings in the Ashlands biome.\n\nOnce you have the materials, interact with the Artisan Table to craft the Black Forge. Place it in your base near other crafting stations for convenience. The Black Forge allows you to craft and upgrade black metal weapons, tools, and armor. Black metal is obtained by defeating Fulings, the goblin-like enemies in the Plains biome. Fulings drop black metal scraps, which can be smelted into black metal bars using a Blast Furnace.\n\nTo use the Black Forge, ensure you have a Blast Furnace nearby. The Blast Furnace is crafted using 20 Fine Wood, 10 Iron, 5 Surtling Cores, and 20 Stone. Smelt black metal scraps into bars, then interact with the Black Forge to craft items like the Black Metal Sword, Black Metal Shield, or Black Metal Atgeir. You can also upgrade these items using additional black metal bars and other resources.\n\nA common challenge is surviving in the Plains biome to farm black metal scraps. Fulings are aggressive and travel in groups, making them dangerous for unprepared players. To mitigate this, equip yourself with high-tier armor, such as Wolf Armor from the Mountains biome, and bring powerful weapons like the Frostner or Draugr Fang bow. Use terrain to your advantage, such as kiting enemies around rocks or trees, and consider building a small outpost near the Plains for quick respawns and storage.\n\nIn summary, unlocking and using the Black Forge requires defeating Moder, crafting the Artisan Table, gathering materials, and smelting black metal. Focus on upgrading your gear and preparing for the dangers of the Plains biome to efficiently farm black metal scraps. With the Black Forge, you can craft some of the strongest gear in Valheim, ensuring your survival in the game''s toughest challenges.\n\nPractical tips: Always carry a portal when exploring the Plains biome to quickly return to your base. Build a Blast Furnace near your Black Forge to streamline the smelting process. Consider farming Surtling Cores early in the game to avoid shortages later. Finally, team up with friends to tackle Fuling camps more effectively and share resources.
