How do you craft a forge cooler, and what does it do?

The Forge Cooler is a crucial upgrade for your Forge in Valheim, allowing you to craft advanced items and improve your gear. It is one of the six Forge upgrades required to unlock the Forge''s full potential. The Forge Cooler specifically enables you to craft items like the Draugr Fang bow, Frostner, and other high-tier weapons and tools that require cooling during the forging process. Without it, you cannot progress to crafting some of the best gear in the game.\n\nTo craft a Forge Cooler, you need to gather specific materials and have access to a Workbench. The required materials are 25 Fine Wood, 10 Copper, and 2 Leather Scraps. 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, and Leather Scraps are crafted from Deer Hides, which are dropped by Deer in the Meadows. Once you have these materials, approach your Workbench and craft the Forge Cooler.\n\nAfter crafting the Forge Cooler, you need to place it near your Forge. The Forge Cooler must be within the Forge''s radius to function. To check if it is properly placed, interact with the Forge and look at the upgrades tab. If the Forge Cooler is correctly positioned, it will appear as an active upgrade. This upgrade is essential for crafting advanced items, so ensure it is always placed correctly.\n\nOne common challenge players face is locating Copper Deposits in the Black Forest. Copper Deposits are large, dark rocks with greenish veins. They are often partially buried, so you may need to dig around them using a pickaxe to fully uncover and mine them. Another challenge is finding Birch trees, as they are less common than other trees in the Meadows. Look for tall, white-barked trees, and use a Bronze Axe or better to chop them down for Fine Wood.\n\nThe Forge Cooler is part of a larger system of Forge upgrades, which include the Forge Bellows, Anvils, and Tool Rack. Each upgrade enhances the Forge''s capabilities, allowing you to craft more advanced items. For example, the Forge Bellows increases the Forge''s temperature, enabling you to smelt higher-tier metals like Silver and Black Metal. The Anvils and Tool Rack improve the Forge''s efficiency and unlock additional crafting recipes. Together, these upgrades make your Forge a powerful tool for crafting and upgrading gear.\n\nFor new players, it is important to prioritize gathering materials for Forge upgrades early in the game. Focus on exploring the Black Forest biome to mine Copper and Tin, which are essential for crafting Bronze tools and weapons. Experienced players should ensure their Forge is fully upgraded before venturing into more dangerous biomes like the Swamp or Mountains, as the advanced gear unlocked by the Forge Cooler will be crucial for survival.\n\nIn summary, the Forge Cooler is a vital upgrade for your Forge in Valheim, enabling you to craft advanced items and improve your gear. Gather 25 Fine Wood, 10 Copper, and 2 Leather Scraps to craft it at a Workbench, and place it near your Forge to activate its benefits. Prioritize exploring the Black Forest for Copper and the Meadows for Fine Wood and Deer Hides. With the Forge Cooler and other upgrades, your Forge will become a cornerstone of your Viking survival journey.
