How do you use the Hammer to build a portal on a remote island?

Building a portal on a remote island in Valheim is a crucial strategy for efficient exploration and resource management. To begin, you must first unlock the ability to craft portals by defeating the first boss, Eikthyr, and obtaining Hard Antlers. These are used to craft an Antler Pickaxe, which allows you to mine Tin and Copper in the Black Forest biome. Once you have these materials, you can craft a Forge and smelt Bronze, which is required to craft the Hammer and other essential tools.\n\nTo build a portal, you need two key items: a Hammer and the required portal materials. The Hammer is crafted at a Workbench using 3 Wood and 2 Stone. Once you have the Hammer, you can use it to place structures, including portals. Portals require 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes. Fine Wood is obtained by chopping down Birch or Oak trees in the Meadows or Black Forest biomes, while Surtling Cores are found in Burial Chambers or by defeating Surtlings in the Ashlands biome. Greydwarf Eyes are dropped by Greydwarfs, common enemies in the Black Forest.\n\nBefore setting sail to a remote island, ensure you have all the necessary materials for building a portal. This includes the Hammer, Fine Wood, Surtling Cores, and Greydwarf Eyes. It’s also wise to bring extra materials in case of mistakes or unexpected challenges. Once you arrive at the remote island, find a safe and flat area to build your portal. Use the Hammer to open the build menu, navigate to the Misc tab, and select the Portal structure. Place the portal frame and interact with it to name it. The name must match the portal you plan to connect it to back at your base.\n\nOne common challenge is running out of materials or forgetting to bring a key item. To avoid this, double-check your inventory before leaving your base. Another issue is finding a safe location on the remote island. Avoid building near hostile creatures or in areas prone to raids. If you encounter enemies while building, use your weapons to clear the area before continuing. Additionally, always carry a Workbench with you, as it is required to repair your Hammer and other tools.\n\nPortals are a game-changing mechanic in Valheim, allowing you to quickly travel between distant locations. However, they do not transport metals or ores, so plan accordingly when gathering resources. For example, if you’re mining Copper or Iron on a remote island, you’ll need to transport these materials back to your base via a Longship or Karve. Portals are best used for quick access to exploration points, boss arenas, or resource-rich areas.\n\nIn summary, building a portal on a remote island requires careful preparation and resource management. Gather all necessary materials, choose a safe location, and ensure your portal names match. By following these steps, you can create a reliable network of portals to streamline your exploration and survival in Valheim. Remember to always carry extra materials and a Workbench to handle unexpected challenges. With these tips, you’ll be well-equipped to conquer the oceans and beyond.
