How do you unlock the forge level 13 upgrade?

Unlocking the forge level 13 upgrade in Valheim is a significant milestone for players looking to craft high-tier gear and weapons. The forge is essential for smelting and crafting advanced items, and upgrading it to level 13 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 have a fully upgraded forge at level 12. This requires all previous forge upgrades, such as the forge cooler, bellows, and anvils. Once your forge is at level 12, the next step is to craft the forge tool rack, which is the final upgrade needed to reach level 13. The forge tool rack requires specific materials that can only be found in the Mistlands biome, making this upgrade one of the most challenging to achieve.\n\nThe Mistlands biome is a late-game area filled with dangerous enemies and unique resources. To craft the forge tool rack, you will need 10 iron, 4 black marble, and 1 Yggdrasil wood. Iron can be obtained by smelting scrap iron found in the Swamp biome, while black marble is mined from ancient structures in the Mistlands. Yggdrasil wood is harvested from the massive, glowing trees scattered throughout the Mistlands. Be prepared for tough battles, as the Mistlands is home to powerful foes like Seekers and Gjalls.\n\nOnce you have gathered the required materials, return to your forge and craft the forge tool rack. This item must be placed near the forge to activate the upgrade. Once placed, your forge will reach level 13, unlocking the ability to craft the highest-tier weapons and armor, such as the Carapace set and Mistwalker sword. This upgrade is crucial for players aiming to tackle the game''s toughest challenges, including the Queen boss in the Mistlands.\n\nA common challenge players face is locating black marble and Yggdrasil wood in the Mistlands. To efficiently gather these resources, bring a pickaxe for mining black marble and a high-level axe for chopping Yggdrasil wood. Additionally, consider bringing a portal to quickly transport materials back to your base. The Mistlands is a dangerous biome, so ensure you have strong armor, weapons, and plenty of healing items before venturing in.\n\nIn summary, unlocking the forge level 13 upgrade requires careful preparation, exploration of the Mistlands biome, and gathering rare materials. By following these steps and overcoming the challenges of the Mistlands, you can upgrade your forge to its maximum level and craft the best gear in Valheim. This upgrade is a testament to your progress and readiness for the game''s most demanding content.
