How do you unlock the forge bellows for advanced forge upgrades?

Unlocking the forge bellows in Valheim is a crucial step for advancing your crafting capabilities, particularly for upgrading your forge to handle higher-tier weapons and tools. The forge bellows are part of the advanced forge upgrades, which allow you to craft and improve items like iron and silver gear. To unlock the forge bellows, you must first progress through the early stages of the game, gather specific resources, and defeat certain enemies to acquire the necessary materials.\n\nTo begin, you need to have a functional forge. The forge is unlocked after crafting a workbench and gathering basic materials like wood, stone, and copper. Once your forge is built, you can start upgrading it with various components, including the forge bellows. However, the forge bellows require specific materials that are not available in the early game. You will need to venture into the Black Forest biome to gather core wood and fine wood, as well as defeat Greydwarfs and Trolls to collect leather scraps and troll hides.\n\nThe primary materials required to craft the forge bellows are fine wood, leather scraps, and a chain. Fine wood is obtained by chopping down birch or oak trees, which are found in the Meadows and Black Forest biomes. Leather scraps are dropped by boars or found in chests, while chains are a bit more challenging to acquire. Chains are dropped by Wraiths, which are ghostly enemies found in the Swamp biome at night, or they can be obtained by defeating the Swamp''s mini-boss, the Wraith. Chains are also occasionally found in Sunken Crypts within the Swamp biome.\n\nOnce you have gathered all the necessary materials, you can craft the forge bellows at your workbench. The recipe requires 5 fine wood, 5 leather scraps, and 1 chain. After crafting, place the forge bellows near your forge to activate its functionality. The bellows increase the forge''s temperature, allowing you to craft and upgrade higher-tier items like iron and silver gear. This upgrade is essential for progressing through the mid-game and preparing for tougher biomes like the Mountains and Plains.\n\nA common challenge players face is locating chains, as they are relatively rare and require venturing into the dangerous Swamp biome. To make this process easier, ensure you are well-prepared with upgraded bronze or iron gear, poison resistance mead, and a reliable weapon. Exploring Sunken Crypts is a safer way to find chains, as they often contain chests with valuable loot. Additionally, Wraiths are easier to defeat at night when they spawn more frequently, but be cautious of other Swamp enemies like Draugr and Leeches.\n\nIn summary, unlocking the forge bellows involves gathering fine wood, leather scraps, and chains, which require exploring the Black Forest and Swamp biomes. Defeating Wraiths or looting Sunken Crypts is the most reliable way to obtain chains. Once crafted, the forge bellows significantly enhance your forge''s capabilities, enabling you to craft advanced gear and progress further in the game. Always prepare thoroughly before venturing into dangerous biomes, and prioritize upgrading your gear to handle tougher enemies.\n\nPractical tips for new players include marking birch and oak trees on your map for easy fine wood farming, taming boars for a steady supply of leather scraps, and using portals to minimize travel time between biomes. For experienced Vikings, consider building a base near the Swamp biome to streamline chain farming and reduce the risk of losing valuable resources. With the forge bellows unlocked, you''ll be well-equipped to tackle Valheim''s mid-game challenges and beyond.
