How do I mark spawn points for cultists in the Mountains?

Marking spawn points for cultists in the Mountains biome is a crucial strategy for efficient resource gathering and preparation in Valheim. Cultists are hostile enemies found near Frost Caves, which are unique dungeon-like structures in the Mountains. These caves are the only locations where you can find Fenris Hair, a rare crafting material used for high-tier armor and gear. To effectively mark these spawn points, you need to understand the game mechanics, prepare the right tools, and follow a systematic approach.\n\nFirst, you must locate Frost Caves in the Mountains biome. These caves are identifiable by their icy entrances and are often found on steep slopes or near large rock formations. To survive in the Mountains, ensure you have Frost Resistance Mead or Wolf Armor equipped, as the cold environment will drain your health otherwise. Bring a pickaxe to mine Silver and other resources, as well as a weapon like a bow or sword to defend yourself against Wolves, Drakes, and Cultists.\n\nOnce you find a Frost Cave, enter cautiously. Cultists are aggressive and will attack on sight. They are typically found in groups, so be prepared for a fight. After clearing the area, use the in-game map to mark the cave entrance. Open your map (default key: M) and right-click to place a custom marker. Label it clearly, such as ''Cultist Cave,'' to differentiate it from other points of interest. This step is essential for future reference, especially if you plan to return for more Fenris Hair or other resources.\n\nA common challenge is navigating the Mountains biome due to its harsh terrain and weather. To mitigate this, consider building a small outpost near the Frost Cave. This outpost can serve as a respawn point and storage area for your loot. Use the Hammer tool to construct a basic shelter with a bed, fire, and chest. This setup will save you time and effort when revisiting the area.\n\nAnother practical tip is to bring a Portal with you. Craft a Portal at your main base and name it. Then, carry the materials to build a second Portal near the Frost Cave. This allows for quick travel between your base and the Mountains, reducing the risk of losing progress or resources. Portals require Fine Wood, Greydwarf Eyes, and Surtling Cores, so ensure you have these materials before venturing out.\n\nFor new players, it’s important to note that Frost Caves are not always easy to find. Explore the Mountains thoroughly, and use the Wishbone item (obtained by defeating Bonemass) to detect Silver deposits, which are often located near Frost Caves. Experienced Vikings can optimize their search by using the Moder boss power, which allows for faster travel across the biome.\n\nIn summary, marking cultist spawn points in the Mountains involves locating Frost Caves, clearing them of enemies, and using the map to mark their locations. Prepare adequately with Frost Resistance, weapons, and tools, and consider building an outpost or Portal for convenience. This strategy ensures you can efficiently farm Fenris Hair and other valuable resources while minimizing risks in this dangerous biome.
