How do I craft a portal to transport metals quickly?

In Valheim, transporting metals like Copper, Tin, and Iron can be a time-consuming process due to their weight and the inability to teleport them through portals. However, portals are still an essential tool for efficient resource management. To craft a portal, you need to unlock the recipe by obtaining Fine Wood and Surtling Cores, which are found in the Black Forest biome. Fine Wood is obtained by chopping down Birch or Oak trees using a Bronze Axe, while Surtling Cores are found in Burial Chambers or dropped by Surtlings in the Ashlands biome.\n\nTo craft a portal, you will need 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes. Once you have the materials, open your crafting menu and select the portal. Place the portal in a secure location near your base or mining site. Portals require two linked structures to function, so you must build a second portal elsewhere and assign both portals the same tag. For example, if you name one portal ''Mine,'' the other portal must also be named ''Mine'' to establish a connection.\n\nWhile portals cannot transport metals, they are invaluable for quickly moving between mining sites and your base. For example, you can set up a portal near a Copper deposit in the Black Forest and another near your smelting area. This allows you to quickly return to your base to repair tools, rest, or drop off non-metal resources. To transport metals, you will need to use a cart or ship. Carts are ideal for overland transport, while ships are better for moving large quantities of ore across water.\n\nA common challenge is managing inventory space while mining. To optimize your workflow, bring a cart to the mining site and load it with ores as you gather them. Once the cart is full, transport it back to your base. If you are mining near water, consider building a Karve or Longship to transport ores more efficiently. Always mark your mining locations on the map to avoid losing track of valuable resources.\n\nFor experienced players, consider setting up a forward base near mining sites. This base can include a smelter and forge, allowing you to process ores on-site and reduce the need for frequent trips. Additionally, always carry materials to build a workbench and portal when exploring new areas. This ensures you can quickly establish a connection to your main base and avoid long treks back.\n\nIn summary, while portals cannot transport metals, they are a crucial tool for efficient resource management in Valheim. By strategically placing portals and using carts or ships for metal transport, you can streamline your mining operations and focus on building and exploring. Always plan ahead, mark resource locations, and consider setting up forward bases to maximize efficiency.
