How do I use portals to farm resources in different biomes?

Portals are one of the most powerful tools in Valheim for efficient resource gathering and exploration. They allow you to fast travel between two linked portals, making it easier to farm resources in different biomes without spending hours traveling. To use portals effectively, you must first craft them using Surtling Cores, Fine Wood, and Greydwarf Eyes. Each portal requires 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes, which can be gathered from dungeons, Greydwarf enemies, and Birch or Oak trees.\n\nTo set up a portal network for resource farming, start by building a portal at your base. Name it something simple like ''Base'' or ''Home.'' Then, venture into the biome where you want to gather resources, such as the Black Forest for Copper and Tin or the Plains for Black Metal and Flax. Once you arrive, place a second portal and give it the same name as the one at your base. This will link the two portals, allowing you to travel instantly between them. Always carry portal materials with you to set up new portals on the fly.\n\nOne common challenge is transporting metal ores, such as Copper, Iron, or Silver, through portals. Unfortunately, Valheim''s game mechanics prevent metal ores and bars from being teleported. To work around this, you can smelt the ores into bars at the resource location and transport the bars back to your base via a Longship or Cart. Alternatively, you can set up a secondary base near the resource-rich area to process materials locally before transporting the final products.\n\nFor example, if you''re farming Iron in the Swamp biome, you can set up a portal near the Crypts for quick access. Use the portal to bring back non-metal resources like Ancient Bark, Guck, or Withered Bones. Then, use a Longship to transport the Iron back to your main base. This strategy saves time and minimizes the risk of losing valuable resources to enemies or storms.\n\nAnother practical tip is to create a dedicated portal hub at your base. This hub should include multiple portals, each named for a specific biome or resource location. For instance, you could have portals labeled ''Swamp,'' ''Mountain,'' and ''Plains'' for quick access to these areas. This setup ensures you can easily switch between biomes without needing to rename portals constantly.\n\nWhen farming in dangerous biomes like the Mountains or Plains, always prepare for combat. Bring healing items, stamina potions, and high-tier weapons. Portals can serve as a quick escape route if you''re overwhelmed by enemies. Additionally, consider building small outposts near your portals in these biomes. These outposts can include a bed, workbench, and storage chests to make resource gathering more efficient.\n\nFinally, remember that portals require a clear path to function. Avoid placing them in cramped spaces or near obstacles that could block their activation. Always test your portals immediately after setting them up to ensure they work correctly. By mastering portal usage, you can streamline your resource farming and exploration, making your Valheim journey more enjoyable and efficient.
