What is the best way to gather surtling cores for portals?

Gathering Surtling Cores in Valheim is essential for crafting portals, which allow fast travel between locations. Surtling Cores are primarily found in Burial Chambers within the Black Forest biome. These dungeons are scattered throughout the biome and are identifiable by their stone entrances with green torches. To begin your search, equip yourself with basic tools like a club, shield, and a torch, as the chambers are dark and filled with hostile skeletons.\n\nTo locate Burial Chambers, explore the Black Forest biome thoroughly. Look for stone structures with green torches outside, as these mark the entrance. Once inside, you’ll encounter skeletons and other enemies, so be prepared for combat. Surtling Cores are typically found in chests or lying on the ground in these chambers. Each Burial Chamber can yield 2-6 cores, so exploring multiple chambers is recommended.\n\nA common challenge is dealing with the skeletons inside Burial Chambers. They are fast and deal significant damage, especially to new players. To counter this, use a shield to block their attacks and strike back with a club or axe. Bringing healing items like cooked meat or berries is also advisable. If you’re struggling, consider upgrading your gear before venturing into the Black Forest.\n\nAnother method to obtain Surtling Cores is by defeating Surtlings, fiery creatures found in the Ashlands biome or near Fire Geysers in the Swamp biome. However, these methods are more advanced and require better gear and preparation. For new players, focusing on Burial Chambers is the safest and most efficient way to gather cores.\n\nOnce you’ve collected enough Surtling Cores, you can craft portals at a workbench. Each portal requires 10 Greydwarf Eyes, 20 Fine Wood, and 2 Surtling Cores. Fine Wood can be obtained by chopping down birch or oak trees in the Meadows or Black Forest biomes. Greydwarf Eyes drop from Greydwarfs, common enemies in the Black Forest.\n\nTo maximize efficiency, mark the locations of Burial Chambers on your map as you explore. This allows you to revisit them later or share their locations with friends in multiplayer. Additionally, consider bringing a pickaxe to mine any valuable resources like tin or copper you might find in the Black Forest while searching for chambers.\n\nIn summary, the best way to gather Surtling Cores for portals is by exploring Burial Chambers in the Black Forest biome. Equip yourself with basic combat gear, bring healing items, and mark dungeon locations on your map. For advanced players, Surtlings in the Ashlands or Swamp biomes can also provide cores, but Burial Chambers remain the most reliable source for new Vikings.
