How do I link two portals together for fast travel?

Linking portals in Valheim is a crucial mechanic for fast travel, allowing you to move quickly between distant locations. To link two portals, you must first craft them using specific materials and ensure they share the same unique tag. Portals require Fine Wood, Greydwarf Eyes, and Surtling Cores, which can be found in the Black Forest biome. Fine Wood is obtained by chopping down birch or oak trees, Greydwarf Eyes drop from Greydwarf enemies, and Surtling Cores are found in Burial Chambers or dropped by Surtlings in the Ashlands biome.\n\nTo craft a portal, you need to unlock the recipe by obtaining at least one Surtling Core. Once crafted, place the portal in your desired location. Each portal has a tag field, which is a customizable name. To link two portals, both must have the exact same tag. For example, if you name one portal ''Home'' and another ''Base,'' they will not connect. However, if both are named ''Home,'' they will link and allow instant travel between them.\n\nWhen placing portals, consider their surroundings. Portals require a flat, open area and cannot be placed too close to other structures or terrain obstacles. If you encounter placement issues, clear the area of rocks, trees, or other objects. Additionally, portals cannot be used to transport certain items, such as metals (e.g., copper, iron, or silver). This limitation encourages exploration and resource management, as you must manually transport these materials.\n\nA common challenge is managing multiple portals in a single location. To avoid confusion, use descriptive tags like ''SwampOutpost'' or ''MountainMine.'' This naming convention helps you quickly identify the destination of each portal. If you accidentally misname a portal, you can rename it by interacting with the tag field and updating it to match the desired destination.\n\nFor new players, it’s recommended to establish a central hub with multiple portals. This hub can serve as your main base, connecting to various biomes like the Meadows, Black Forest, Swamp, and Mountains. Experienced Vikings can optimize portal networks by creating temporary portals for resource gathering or exploration. For example, when mining in the Mountains, place a portal near your mining site and link it to your base for quick ore transport.\n\nIn summary, linking portals in Valheim involves crafting them with Fine Wood, Greydwarf Eyes, and Surtling Cores, ensuring they share the same tag, and placing them in accessible locations. Use descriptive tags to manage multiple portals and plan your network strategically to maximize efficiency. Remember that portals cannot transport metals, so plan your resource trips accordingly. With a well-organized portal system, you can explore Valheim’s vast world with ease and efficiency.
