What is the best strategy for defeating Bonemass in the Swamp biome?

Defeating Bonemass, the third boss in Valheim, requires careful preparation and strategy. Bonemass is located in the Swamp biome and is resistant to most damage types except blunt weapons. To begin, ensure you have the best gear available before engaging. This includes upgrading your armor to at least Iron-tier, crafting a Mace (blunt weapon), and preparing healing meads and poison resistance meads. Bonemass is weak to blunt damage, so a fully upgraded Iron Mace is highly recommended.\n\nBefore heading to the Swamp, gather resources to craft Poison Resistance Mead. Bonemass uses poison attacks that can quickly drain your health, and the mead will significantly reduce this damage. To craft Poison Resistance Mead, you need Honey, Thistle, Coal, and Neck Tails. Brew these at a Fermenter, which requires Bronze and Fine Wood to craft. Additionally, stock up on Healing Mead and Stamina Mead to sustain yourself during the fight.\n\nWhen you arrive at the Swamp, locate Bonemass''s summoning altar. Clear the area around the altar of enemies and obstacles to create a safe fighting space. Bonemass will spawn a large number of adds during the fight, so having a clear area to maneuver is crucial. Build a small base nearby with a portal to your main base for quick resupply if needed. This base should include a bed for respawning, a workbench for repairs, and chests for storing extra supplies.\n\nDuring the fight, focus on using your Mace for maximum damage. Bonemass has three main attacks: a melee swipe, a poison cloud, and a vomit attack that spawns adds. Dodge his melee attacks by rolling or moving out of range. When he uses his poison cloud, retreat and wait for it to dissipate while using your Poison Resistance Mead. When he vomits, quickly kill the spawned adds to avoid being overwhelmed. Use your Healing Mead to recover health and Stamina Mead to maintain mobility.\n\nA common mistake is underestimating Bonemass''s adds. They can quickly overwhelm you if not dealt with promptly. Use area-of-effect (AoE) attacks like the Iron Sledge or secondary Mace attacks to clear them efficiently. If you''re playing with friends, assign roles such as tanking Bonemass and clearing adds to make the fight more manageable. Communication and coordination are key in multiplayer.\n\nAfter defeating Bonemass, you will receive the Wishbone, which allows you to locate hidden treasures like Silver in the Mountains biome. This is a significant upgrade for your gear progression. Use the Wishbone to find Silver Ore and craft Wolf Armor and Frostner, a powerful blunt weapon for future challenges.\n\nIn summary, defeating Bonemass requires preparation, the right gear, and a solid strategy. Focus on blunt damage, use Poison Resistance Mead, and clear adds quickly. With these tips, you''ll be ready to take on this challenging boss and progress further in Valheim.
