How do I build a portal and what resources are needed?

Building a portal in Valheim is a crucial step for efficient travel across the vast world. Portals allow you to instantly teleport between two linked locations, saving time and resources. To build a portal, you must first unlock the recipe by obtaining Surtling Cores, which are found in Burial Chambers in the Black Forest biome or dropped by Surtlings in the Ashlands biome. Once you have the recipe, you can craft a portal at a Workbench using 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes.\n\nTo begin, gather the required resources. Fine Wood is obtained by chopping down Birch or Oak trees, which are found in the Meadows and Black Forest biomes. Surtling Cores are rare but essential; explore Burial Chambers thoroughly to collect them. Greydwarf Eyes are dropped by Greydwarfs, common enemies in the Black Forest. Once you have all the materials, craft the portal at a Workbench.\n\nNext, place the portal in your desired location. Portals require a flat surface and enough space to function properly. Once placed, you must name the portal by interacting with it. The name is case-sensitive and must match the name of the portal you wish to link to. For example, if you name a portal ''Home,'' the other portal must also be named ''Home'' to establish a connection.\n\nA common challenge is running out of Surtling Cores early in the game. To overcome this, prioritize exploring Burial Chambers in the Black Forest. These dungeons often contain multiple Surtling Cores, making them a reliable source. Additionally, avoid using portals for transporting metals like Copper or Iron, as these items cannot be teleported. Instead, use a cart or ship to transport metals manually.\n\nPortals are especially useful for connecting distant bases or resource-rich areas. For example, if you establish a base in the Meadows and find a valuable resource in the Mountains, you can build a portal to quickly travel between the two locations. This saves time and reduces the risk of losing valuable items during long journeys.\n\nIn summary, building a portal in Valheim requires 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes. Gather these resources, craft the portal at a Workbench, and place it in a suitable location. Name the portal carefully to ensure proper linking. Use portals strategically to enhance your survival and exploration efficiency in the game.
