How do I set up a portal for farming resources in the Mountains?

Setting up a portal for farming resources in the Mountains biome in Valheim is a strategic way to save time and ensure efficient resource gathering. Portals allow you to fast travel between two linked points, making it easier to transport heavy or valuable items like Silver, Obsidian, and Dragon Tears. To begin, you must first unlock the ability to craft portals by defeating the second boss, The Elder, and obtaining the Swamp Key. This key grants access to Sunken Crypts, where you can find Surtling Cores, a critical component for crafting portals.\n\nTo craft a portal, you will need 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes. Fine Wood can be obtained by chopping down Birch or Oak trees in the Meadows or Black Forest biomes. Surtling Cores are found in Burial Chambers, Sunken Crypts, or by defeating Surtlings in the Ashlands or Swamp biomes. Greydwarf Eyes drop from Greydwarfs, which are common enemies in the Black Forest. Once you have the materials, craft a portal at a Workbench and place it in a secure location near your base or another strategic point.\n\nWhen setting up a portal in the Mountains biome, choose a location that is safe from enemy attacks and close to the resources you want to farm. For example, place the portal near a Silver vein or a Draugr village for easy access to valuable loot. Ensure the area is cleared of Wolves, Drakes, and Stone Golems, as these enemies can destroy your portal if left unchecked. Building a small shelter around the portal can protect it from weather and enemies, ensuring it remains functional.\n\nTo link two portals, you must give them the same tag. When placing a portal, you will see an option to name it. Use a simple, memorable tag like ''Mountains'' or ''SilverFarm'' to avoid confusion. Once both portals are named identically, they will automatically connect, allowing you to fast travel between them. This is particularly useful for transporting heavy resources like Silver Ore, which cannot be carried through portals unless smelted into Silver Ingots.\n\nOne common challenge when farming in the Mountains is the cold weather, which drains your health unless you have Frost Resistance. To counter this, craft a Wolf Fur Cape or Frost Resistance Mead. The Wolf Fur Cape requires Silver and Wolf Pelts, while Frost Resistance Mead is brewed using Honey, Thistle, Bloodbags, and Greydwarf Eyes at a Fermenter. Always carry these items when venturing into the Mountains to avoid freezing to death.\n\nAnother practical tip is to set up a secondary portal at your base for emergencies. If your primary portal in the Mountains is destroyed or you need to quickly return home, having a backup ensures you don''t lose progress. Additionally, consider building a small outpost near your Mountain portal with a bed, chests, and a Workbench. This allows you to respawn nearby if you die and provides storage for excess resources.\n\nIn summary, setting up a portal for farming resources in the Mountains biome requires careful planning and preparation. Gather the necessary materials, choose a safe location, and link your portals with a unique tag. Protect your portal from enemies and the cold, and always have a backup plan in case of emergencies. By following these steps, you can efficiently farm valuable resources and make the most of your time in Valheim''s challenging Mountain biome.
