What’s the fastest way to upgrade your forge to level 4?

Upgrading your forge to level 4 in Valheim is essential for crafting advanced gear and progressing through the game. The forge is a critical workstation for refining metals and crafting weapons, tools, and armor. To reach level 4, you need to build and place specific upgrades around the forge. Each upgrade increases the forge''s level by one, and you need three upgrades to go from level 1 to level 4.\n\nFirst, you need to craft a forge. This requires 4 stone, 4 coal, 10 wood, and 6 copper. Once built, you can start upgrading it. The three upgrades required for level 4 are the Forge Cooler, Forge Bellows, and Forge Toolrack. Each of these requires specific materials and access to different biomes.\n\nThe Forge Cooler requires 25 fine wood and 10 copper. Fine wood is obtained by chopping down birch or oak trees in the Meadows or Black Forest biomes. Copper is mined from copper deposits in the Black Forest. Once you have the materials, craft the Forge Cooler and place it near the forge to increase its level by one.\n\nThe Forge Bellows requires 5 fine wood, 4 leather scraps, and 4 chain. Fine wood is gathered as described earlier. Leather scraps are obtained by hunting boars in the Meadows or killing draugr in the Swamp biome. Chains are a bit trickier to acquire; they can be found in chests in the Swamp biome or dropped by Wraiths, which spawn at night in the Swamp. Once you have the materials, craft the Forge Bellows and place it near the forge to increase its level by another one.\n\nThe Forge Toolrack requires 15 fine wood and 10 iron. Fine wood is gathered as before. Iron is obtained by smelting scrap iron, which is found in Muddy Scrap Piles in the Swamp biome. You need a Wishbone to locate these piles, which is dropped by Bonemass, the third boss. Once you have the materials, craft the Forge Toolrack and place it near the forge to reach level 4.\n\nA common challenge is acquiring chains early in the game. If you''re struggling to find chains, focus on exploring the Swamp biome at night to encounter Wraiths. Alternatively, you can find chains in Sunken Crypts, which are scattered throughout the Swamp. Another challenge is gathering enough fine wood. If you''re having trouble, prioritize upgrading your axe to bronze or iron to make chopping birch and oak trees easier.\n\nTo speed up the process, plan your resource gathering efficiently. Start by mining copper and tin in the Black Forest to craft bronze tools, which will make gathering fine wood and other materials faster. Next, venture into the Swamp biome to collect iron and chains. Always carry a portal with you to quickly return to your base and deposit materials. This minimizes downtime and keeps you focused on upgrading your forge.\n\nIn summary, upgrading your forge to level 4 requires gathering fine wood, copper, leather scraps, chains, and iron. Focus on exploring the Meadows, Black Forest, and Swamp biomes to collect these materials. Use efficient resource-gathering strategies and prioritize crafting upgrades to speed up the process. With a level 4 forge, you''ll be well-equipped to tackle Valheim''s toughest challenges.
