How do you unlock the forge level 14 upgrade?

Unlocking the forge level 14 upgrade in Valheim is a significant milestone for players looking to craft the most powerful gear and weapons. The forge is essential for refining metals and crafting advanced items, and upgrading it to level 14 requires specific materials and progression through the game. To achieve this, you must first understand the mechanics of forge upgrades and the materials needed for each level.\n\nTo begin, the forge can be upgraded by placing specific items near it. These items act as upgrades and increase the forge''s level, allowing you to craft higher-tier gear. Forge level 14 requires a total of 14 upgrades, each unlocked by placing specific items nearby. These items include the forge cooler, forge bellows, anvils, and more. Each upgrade item must be crafted using materials gathered from various biomes and bosses.\n\nTo unlock forge level 14, you need to gather and craft the following upgrade items: the forge cooler (requires 25 fine wood and 10 copper), the forge bellows (requires 5 wood and 5 leather scraps), the anvils (requires 2 bronze and 5 wood), the forge tool rack (requires 15 iron and 10 wood), and the sharpening stone (requires 5 stone and 5 wood). Additionally, you will need the smelter and charcoal kiln to process raw materials like copper, tin, and iron.\n\nOne of the most challenging aspects of this process is gathering iron, which is required for the forge tool rack. Iron can only be found in the Swamp biome, inside Sunken Crypts. To access these crypts, you will need the Swamp Key, which is dropped by the second boss, The Elder. Once you have the key, explore the Swamp biome, locate Sunken Crypts, and mine muddy scrap piles inside to obtain scrap iron. Smelt the scrap iron in a smelter to produce iron bars.\n\nAnother common challenge is obtaining fine wood, which is required for the forge cooler. Fine wood is obtained by chopping down birch or oak trees in the Meadows or Plains biomes. However, these trees require a bronze axe or better to chop. To craft a bronze axe, you will need to mine copper and tin in the Black Forest biome, smelt them into bronze, and then craft the axe at a forge.\n\nOnce you have all the required materials, return to your forge and place the upgrade items nearby. Each item will increase the forge''s level by one, up to a maximum of level 14. Ensure that the items are placed within the forge''s radius, as they will not contribute to the upgrade if they are too far away. You can check the forge''s current level by interacting with it.\n\nPractical tips for this process include setting up a base near the Swamp biome to minimize travel time when farming iron. Additionally, always carry a portal with you to quickly return to your base with heavy materials like iron. For new players, focus on defeating The Elder boss early to gain access to the Swamp biome and its resources. Experienced Vikings should prioritize upgrading their forge as soon as possible to unlock advanced crafting options.\n\nIn summary, unlocking forge level 14 requires gathering materials from multiple biomes, defeating bosses, and crafting specific upgrade items. By following these steps and utilizing practical tips, you can efficiently upgrade your forge and craft the best gear in Valheim.
