What’s the best way to calculate the amount of greydwarf eyes for portal networks?

Calculating the number of greydwarf eyes needed for portal networks in Valheim is essential for efficient travel and resource management. Greydwarf eyes are a key crafting material used to create portals, which allow players to instantly travel between two connected points. Each portal requires 10 greydwarf eyes, 20 fine wood, and 2 surtling cores. To determine how many eyes you need, you must first decide how many portals you plan to build and how many connections you want to establish.\n\nTo start, identify the locations where you want to place portals. Common portal destinations include your main base, resource-rich biomes like the Black Forest or Swamp, and boss arenas. Each portal pair requires two portals, one at the starting point and one at the destination. For example, if you want to connect your base to a Black Forest mining outpost, you’ll need two portals, totaling 20 greydwarf eyes (10 per portal).\n\nNext, consider the number of portal pairs you need. If you plan to connect multiple locations, multiply the number of portal pairs by 20 greydwarf eyes. For instance, connecting your base to three different locations (e.g., a swamp, a mountain, and a plains biome) would require six portals and 60 greydwarf eyes. Always account for extra portals in case you discover new areas or need to relocate existing ones.\n\nGreydwarf eyes are primarily obtained by defeating greydwarfs, which are common enemies in the Black Forest biome. These creatures drop 1-2 eyes per kill, so farming them is relatively straightforward. To maximize efficiency, equip a bow or melee weapon and hunt greydwarfs at night when they spawn more frequently. Alternatively, you can set up a greydwarf farm by creating a spawner trap using a greydwarf nest and a pit or enclosed area.\n\nOne common challenge is running out of greydwarf eyes mid-project. To avoid this, always gather more eyes than you think you’ll need. A good rule of thumb is to collect at least 50% more than your initial calculation. For example, if you need 60 eyes for three portal pairs, aim to collect 90. This buffer ensures you have enough materials for unexpected needs or future expansions.\n\nAnother tip is to prioritize portal placement in high-traffic areas. For example, placing a portal near a copper or tin deposit in the Black Forest can save significant travel time. Similarly, having a portal near a swamp crypt or mountain silver vein can streamline resource gathering. Always mark portal locations on your map to avoid confusion and ensure easy navigation.\n\nFinally, remember that portals cannot transport certain items, such as metals. Plan your resource transportation accordingly, and consider building temporary portals for specific tasks. For example, if you’re mining silver in the mountains, you can set up a temporary portal to quickly return to your base for repairs or storage.\n\nIn summary, calculating greydwarf eyes for portal networks involves determining the number of portal pairs you need, multiplying by 20 eyes per pair, and gathering extra eyes as a buffer. Farm greydwarfs in the Black Forest biome, prioritize high-traffic portal locations, and plan for item transportation restrictions. With these strategies, you can create an efficient portal network that enhances your Valheim experience.
