How do you unlock the forge level 10 upgrade?

Unlocking the forge level 10 upgrade in Valheim is a significant milestone for players looking to craft the best gear and weapons. The forge is essential for refining metals and crafting advanced items, and upgrading it to level 10 requires specific materials and steps. This guide will walk you through the process, including the necessary items, biome exploration, and crafting requirements.\n\nTo begin, you must first build a basic forge. This requires 4 stone, 4 coal, 10 wood, and 6 copper. Once your forge is constructed, you can start upgrading it. Each upgrade level requires specific items, and reaching level 10 involves adding six different forge upgrades: the forge cooler, anvils, the tool rack, the bellows, the grindstone, and the forge tool. Each of these upgrades must be crafted and attached to the forge to increase its level.\n\nThe first upgrade, the forge cooler, requires 25 fine wood and 10 copper. Fine wood can be 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 crafted, place the forge cooler near your forge to increase its level by one.\n\nNext, you need to craft the anvils. There are two types: the small anvil and the large anvil. The small anvil requires 5 wood and 2 bronze, while the large anvil requires 20 iron and 2 wood. Bronze is crafted by combining copper and tin at the forge, and iron is obtained by smelting scrap iron found in the Swamp biome''s Sunken Crypts. Attach the anvils to your forge to further increase its level.\n\nThe tool rack is another essential upgrade, requiring 15 fine wood and 10 iron. This upgrade is particularly useful for organizing your tools and improving the forge''s functionality. Place the tool rack near your forge to unlock the next level.\n\nThe bellows upgrade requires 5 wood and 5 deer hide. Deer hide is obtained by hunting deer in the Meadows biome. The bellows increase the forge''s efficiency, allowing you to smelt metals faster. Attach the bellows to your forge to progress to the next level.\n\nThe grindstone is a critical upgrade for sharpening tools and weapons. It requires 25 wood, 1 sharpening stone, and 5 iron. Sharpening stones are crafted at the stonecutter using 5 stone. Place the grindstone near your forge to unlock the next upgrade level.\n\nFinally, the forge tool upgrade requires 10 iron and 4 fine wood. This upgrade is the last step to reaching forge level 10. Once crafted and attached, your forge will be fully upgraded, allowing you to craft the highest-tier items in the game.\n\nCommon challenges include finding enough resources, especially iron, which requires venturing into the dangerous Swamp biome. To overcome this, ensure you have adequate gear, such as bronze or iron armor, and bring plenty of healing items. Additionally, building a portal near your mining site can save time and resources.\n\nIn summary, unlocking forge level 10 requires gathering specific materials from various biomes, crafting the necessary upgrades, and attaching them to your forge. By following these steps and preparing for the challenges of resource gathering, you can fully upgrade your forge and craft the best gear in Valheim.
