How do you unlock the forge bellows for increased temperature?

Unlocking the forge bellows in Valheim is a crucial step for upgrading your forge and increasing its temperature, which is necessary for crafting higher-tier items like iron and silver gear. The forge bellows allow you to smelt and refine metals more efficiently, making it an essential upgrade for mid-to-late-game progression. To unlock the forge bellows, you must first progress through the game''s early stages, gather specific resources, and defeat certain enemies to acquire the required materials.\n\nTo begin, you need to craft a forge, which requires 6 copper, 4 wood, 4 stone, and 10 coal. Copper is obtained by mining copper deposits in the Black Forest biome, while coal can be acquired by burning wood in a charcoal kiln or defeating surtlings in the Swamp biome. Once your forge is built, you can start upgrading it with various components, including the forge bellows. However, the bellows require specific materials that are not available in the early game.\n\nThe forge bellows require 5 fine wood, 4 bronze nails, and 4 leather scraps to craft. Fine wood is obtained by chopping down birch or oak trees in the Meadows or Black Forest biomes using a bronze axe or better. Bronze nails are crafted at a forge using bronze, which is made by combining copper and tin at a smelter. Leather scraps are dropped by boars or found in chests throughout the world. Gathering these materials may take some time, especially if you are new to the game, but they are essential for progressing your crafting capabilities.\n\nOne common challenge players face is locating birch trees for fine wood. Birch trees are tall, white-barked trees found in the Meadows biome, but they require a bronze axe or higher to chop down. If you are struggling to find birch trees, explore the edges of the Black Forest biome, as they often spawn near the border. Additionally, bronze nails require tin, which is found near water sources in the Black Forest. Use a pickaxe to mine tin deposits, then combine it with copper at a smelter to create bronze.\n\nOnce you have gathered all the required materials, open your crafting menu at the forge and select the forge bellows. Place the bellows near your forge to increase its temperature, allowing you to smelt higher-tier metals like iron and silver. The bellows are a permanent upgrade, so you only need to craft them once. However, you may want to build additional forges in different locations to streamline your crafting process.\n\nIn summary, unlocking the forge bellows requires gathering fine wood, bronze nails, and leather scraps. These materials are obtained by exploring the Meadows and Black Forest biomes, defeating enemies, and refining resources at a smelter. Once crafted, the forge bellows significantly improve your forge''s capabilities, enabling you to craft advanced gear and progress further in the game. For new players, focus on upgrading your tools and exploring thoroughly to gather the necessary resources. Experienced Vikings can optimize their resource gathering by setting up efficient mining and farming operations in key biomes.\n\nPractical tips: Always carry a bronze axe when exploring the Meadows to harvest fine wood on the go. Build a portal near your mining operations in the Black Forest to quickly transport copper and tin back to your base. Finally, consider taming boars in a pen near your base to farm leather scraps passively. These strategies will save time and ensure you have the resources needed for forge upgrades.
