What’s the best way to mark the locations of surtling geysers for coal farming?

Marking the locations of surtling geysers for coal farming in Valheim is a crucial strategy for efficient resource gathering. Surtling geysers are found in the Swamp biome and are a reliable source of coal, surtling cores, and occasionally trophies. To maximize your coal farming efficiency, you need to identify, mark, and revisit these geysers systematically.\n\nFirst, you must locate surtling geysers in the Swamp biome. These geysers emit fire and are surrounded by water, making them easy to spot. When you find one, open your map (default key: M) and place a custom marker. Use a clear and consistent naming convention, such as ''Coal 1'' or ''Surtling Geyser A,'' to avoid confusion later. This step is essential for organizing multiple geysers across your world.\n\nOnce you''ve marked the geyser, consider building a small outpost nearby. This outpost can include a workbench, a portal, and a chest for storing coal and other resources. Portals are especially useful because they allow you to quickly travel between your base and the geyser location. To craft a portal, you need 20 fine wood, 10 greydwarf eyes, and 2 surtling cores. Fine wood can be obtained from birch or oak trees in the Meadows or Black Forest biomes, while greydwarf eyes drop from greydwarfs.\n\nTo farm coal efficiently, you need to clear the area around the geyser. Surtlings spawn from the geyser and drop coal and cores when killed. However, they are weak to water, so standing in the shallow water near the geyser will cause them to take damage and die quickly. This mechanic allows you to farm coal passively without engaging in combat. Make sure to clear any nearby enemies, such as draugr or leeches, to avoid interruptions.\n\nA common challenge is managing inventory space while farming coal. Since coal stacks up to 50, it can fill your inventory quickly. To address this, place a chest near the geyser to store excess coal. You can also use a cart to transport large quantities of coal back to your base. Carts require 20 wood and 10 bronze nails to craft, making them a mid-game solution for resource transportation.\n\nFor new players, it''s important to note that surtling geysers are only found in the Swamp biome, which can be dangerous due to hostile creatures and environmental hazards. Ensure you have adequate gear, such as bronze or iron armor, and bring healing items like cooked meat or mead. Experienced players can optimize their farming routes by linking multiple geysers with portals and creating a network of outposts.\n\nIn summary, the best way to mark and farm surtling geysers involves locating them in the Swamp biome, marking them on your map, building nearby outposts with portals, and using water to kill surtlings efficiently. Organize your inventory with chests or carts, and always prioritize safety when exploring the Swamp. By following these steps, you can establish a reliable coal farming system to fuel your Valheim adventures.
