How do you unlock the wishbone for finding silver veins?

To unlock the wishbone in Valheim, which is essential for finding silver veins, you must first defeat the third boss, Bonemass. This boss is found in the Swamp biome and requires preparation to defeat. The wishbone is a reward for defeating Bonemass, and it allows you to detect hidden silver deposits in the Mountains biome.\n\nTo begin, you need to locate Bonemass''s summoning altar. This altar is marked by a Vegvisir runestone found in Sunken Crypts within the Swamp biome. Sunken Crypts are dungeon-like structures filled with Draugr and other enemies. You will need a Swamp Key to enter these crypts, which is obtained by defeating the second boss, The Elder. Once inside, search for the Vegvisir runestone to reveal Bonemass''s location.\n\nBefore facing Bonemass, ensure you are well-prepared. This boss is resistant to most damage types except blunt weapons, so craft a mace or similar weapon. Poison resistance is also crucial, as Bonemass uses poison attacks. Craft Poison Resistance Mead using ingredients like Honey, Thistle, and Neck Tail. Additionally, wear upgraded Iron Armor for better defense and bring healing items like Cooked Meat and Health Mead.\n\nOnce you defeat Bonemass, you will receive the wishbone as a reward. Equip the wishbone in your inventory, and it will start pulsing and making a sound when you are near buried treasure or silver veins. Silver veins are found exclusively in the Mountains biome, so head there to begin your search. The wishbone''s range is limited, so move methodically across the biome to cover more ground.\n\nWhen the wishbone activates, dig into the ground using a pickaxe to uncover the silver vein. Silver is a valuable resource used to craft high-tier weapons and armor, such as the Wolf Armor set and Draugr Fang bow. Be cautious while mining in the Mountains biome, as it is home to dangerous enemies like Wolves, Drakes, and Stone Golems. Bring Frost Resistance Mead or wear Wolf Armor to avoid freezing damage.\n\nA common challenge players face is locating Bonemass''s altar. If you struggle to find a Sunken Crypt, explore multiple Swamp biomes until you locate one. Another issue is surviving the Mountains biome. Always carry a portal with you to quickly escape if overwhelmed by enemies. Finally, ensure your pickaxe is upgraded to mine silver efficiently, as it requires a high-tier pickaxe like the Iron Pickaxe.\n\nIn summary, unlocking the wishbone involves defeating Bonemass in the Swamp biome, equipping the wishbone, and using it to locate silver veins in the Mountains biome. Prepare thoroughly for the boss fight, and take precautions when mining in the Mountains. With the wishbone, you can access valuable silver resources to enhance your gear and progress further in Valheim.
