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

Portals in Valheim are one of the most powerful tools for efficient resource farming across multiple biomes. They allow you to quickly travel between locations, saving time and effort when gathering materials. To use portals effectively, you must first craft them using resources like Fine Wood, Greydwarf Eyes, and Surtling Cores. Each portal requires a pair of matching tags to function, so planning your portal network is essential.\n\nTo start, gather the necessary materials: 20 Fine Wood, 2 Surtling Cores, and 10 Greydwarf Eyes. Fine Wood can be obtained by chopping Birch or Oak trees, while Greydwarf Eyes drop from Greydwarfs in the Black Forest. Surtling Cores are found in Burial Chambers or by defeating Surtlings in the Ashlands biome. Once you have the materials, craft a portal at your base and another at your desired farming location.\n\nWhen setting up portals, always assign unique tags to each pair. For example, if you''re farming Copper in the Black Forest, name one portal ''Forest1'' and its pair ''Forest1'' as well. This ensures they connect properly. Place the second portal near a resource-rich area, such as a Copper node or a dense patch of Thistle. Repeat this process for other biomes, such as the Mountains for Silver or the Plains for Black Metal.\n\nOne common challenge is transporting metal ores, as they cannot be carried through portals. To overcome this, set up a temporary base near the resource site. Smelt the ores into bars on-site, then transport the bars through the portal. For example, if you''re mining Iron in the Swamp, build a Forge and Smelter nearby to process the ore before returning to your main base.\n\nAnother tip is to use portals for quick escapes during dangerous farming trips. If you''re gathering Obsidian in the Mountains, place a portal near the resource but in a safe location. This allows you to retreat quickly if a pack of Wolves or a Stone Golem appears. Always carry portal materials with you when exploring new biomes to establish quick travel points.\n\nFor advanced players, consider creating a central hub with multiple portals. Label each portal clearly with its destination, such as ''SwampIron'' or ''PlainsFarming.'' This organized approach saves time and ensures you can access any biome quickly. Additionally, always carry extra portal materials in case you need to set up a new pair while exploring.\n\nFinally, remember that portals are not indestructible. Enemies can destroy them if left unprotected. Build a small shelter or fence around your portals to keep them safe. This is especially important in hostile biomes like the Plains or Mountains, where enemies are more aggressive.\n\nBy using portals strategically, you can efficiently farm resources across multiple biomes without wasting time traveling long distances. Plan your portal network carefully, protect your portals, and always be prepared with backup materials. This approach will make your resource-gathering expeditions faster and safer, allowing you to focus on building and progressing in Valheim.
