How can players use the Frostner hammer against Bonemass?

The Frostner hammer is a powerful weapon in Valheim, especially effective against Bonemass, the third boss in the game. Frostner is a silver-tier weapon crafted at the Forge, requiring 10 Ancient Bark, 30 Silver, 5 Ymir Flesh, and 5 Freeze Glands. Its unique combination of frost and spirit damage makes it particularly useful against Bonemass, who is weak to frost damage and resistant to most other types.\n\nTo craft Frostner, players must first defeat the second boss, The Elder, to obtain the Swamp Key. This key allows access to Sunken Crypts in the Swamp biome, where players can gather Iron and craft the necessary tools to mine Silver in the Mountain biome. Once Silver is obtained, players can craft Frostner at a level 3 Forge. Preparation is key, as Bonemass is a challenging boss with high health and devastating attacks.\n\nWhen fighting Bonemass, Frostner''s frost damage slows the boss, reducing its movement speed and attack frequency. This gives players more time to dodge its melee attacks and toxic AoE (Area of Effect) abilities. The spirit damage component of Frostner also helps deal additional damage to Bonemass, as it is undead. Equipping Frostner with a high-level shield, such as the Iron Buckler or Silver Shield, is recommended to block or parry Bonemass''s attacks effectively.\n\nDuring the fight, players should focus on positioning and stamina management. Bonemass summons adds, such as Blobs and Skeletons, which can overwhelm players if not dealt with quickly. Frostner''s AoE damage can help clear these adds while still damaging Bonemass. Players should also bring Poison Resistance Mead, as Bonemass''s toxic attacks can quickly drain health. Consuming stamina-boosting foods like Serpent Stew or Turnip Stew is essential to maintain mobility and attack frequency.\n\nA practical strategy is to build a small platform or treehouse near the Bonemass altar to provide a safe spot for healing and stamina recovery. This also allows ranged players to support the melee fighters using Frostner. Coordination in co-op is crucial, as one player can focus on tanking Bonemass with Frostner while others deal with adds or provide ranged support.\n\nIn summary, Frostner is an excellent weapon for the Bonemass fight due to its frost and spirit damage. Crafting it requires preparation and exploration of the Mountain biome, but the effort is well worth it. By combining Frostner with proper positioning, stamina management, and teamwork, players can overcome Bonemass and progress further in Valheim.\n\nPractical tips for using Frostner against Bonemass include upgrading it to at least level 3 for maximum damage, using a shield to block or parry attacks, and bringing plenty of healing and stamina items. Building a safe spot near the altar can also provide a tactical advantage. With these strategies, players can confidently face Bonemass and emerge victorious.
