What is the best way to farm Surtling Cores for crafting portals?

Farming Surtling Cores in Valheim is essential for crafting portals, which allow you to fast-travel between locations. Surtling Cores are primarily found in Burial Chambers in the Black Forest biome or by defeating Surtlings in the Ashlands or Swamp biomes. For new players, Burial Chambers are the most accessible source, while experienced Vikings can farm Surtlings more efficiently in the Swamp or Ashlands.\n\nTo begin farming Surtling Cores in Burial Chambers, you’ll need to explore the Black Forest biome. Look for stone structures with green torches outside, as these mark the entrance to Burial Chambers. Bring a weapon, shield, and some food for stamina and health regeneration. Inside, you’ll encounter Skeletons and Ghosts, so be prepared for combat. Surtling Cores are found in chests or lying on the ground in these chambers. Clear the area of enemies and loot thoroughly to maximize your yield.\n\nFor experienced players, farming Surtlings in the Swamp biome is a faster method. Surtlings spawn naturally in the Swamp, often near Fire Geysers. These geysers are small, bubbling pools of fire that continuously spawn Surtlings. To farm efficiently, dig around the Fire Geyser to lower the ground level until it’s submerged in water. This will instantly kill any Surtlings that spawn, allowing you to collect their drops, including Surtling Cores, without engaging in combat. This method is highly effective and requires minimal effort once the geyser is submerged.\n\nAnother option is to venture into the Ashlands biome, where Surtlings are abundant. However, this biome is dangerous and only recommended for well-equipped players. Bring fire-resistant gear and powerful weapons to handle the high-level enemies in this area. Surtlings in the Ashlands drop Surtling Cores frequently, making it a viable farming spot for late-game players.\n\nWhen farming Surtling Cores, always bring a pickaxe to clear obstacles in Burial Chambers or modify terrain in the Swamp. Additionally, carry a portal with you to quickly return to your base and unload your loot. This saves time and reduces the risk of losing your items if you die. If you’re farming in the Swamp, consider building a small outpost nearby to store resources and rest.\n\nA common challenge is dealing with the high number of enemies in Burial Chambers or the Swamp. To mitigate this, use a bow to pick off enemies from a distance or bring a friend for co-op play. In the Swamp, watch out for Leeches and Draugr, which can overwhelm you if you’re not careful. Always keep an eye on your stamina and health, and avoid fighting multiple enemies at once.\n\nIn summary, the best way to farm Surtling Cores depends on your progression in the game. New players should focus on Burial Chambers in the Black Forest, while experienced players can efficiently farm Surtlings in the Swamp or Ashlands. Use terrain manipulation in the Swamp to automate Surtling kills, and always prepare adequately for combat. With these strategies, you’ll have plenty of Surtling Cores for crafting portals and other essential items.
