How can you use the Bonemass power to tank damage during boss fights?

The Bonemass power is one of the most valuable tools in Valheim for tanking damage during boss fights, especially when facing high-damage enemies like Moder or Yagluth. This power, unlocked by defeating the Bonemass boss in the Swamp biome, reduces all physical damage taken by 50% for 5 minutes. This makes it an essential ability for surviving tough encounters, particularly when you''re outnumbered or facing enemies with devastating attacks.\n\nTo activate the Bonemass power, you must first defeat the Bonemass boss in the Swamp biome. This requires preparation, including crafting a Mace (Bonemass is weak to blunt damage), Poison Resistance Mead, and high-tier armor like Iron or Wolf Armor. Once defeated, you can place the Bonemass Trophy on the central stone at your spawn point to unlock the power. To use it, press F to open the power wheel and select the Bonemass icon. This will activate the damage reduction buff, which lasts for 5 minutes and has a 20-minute cooldown.\n\nDuring boss fights, timing is crucial when using the Bonemass power. Activate it just before engaging the boss or when you anticipate a heavy attack. For example, when fighting Moder, the dragon boss in the Mountains biome, use the power when she begins her frost breath attack or when she lands for melee combat. This will significantly reduce the damage you take, allowing you to focus on dealing damage without worrying about your health dropping too quickly.\n\nAnother practical use for the Bonemass power is during group fights or when dealing with multiple enemies. For instance, when exploring the Plains biome and encountering a group of Fulings or a Deathsquito swarm, activating the power can save you from being overwhelmed. The 50% damage reduction applies to all physical attacks, making it a lifesaver in chaotic situations.\n\nTo maximize the effectiveness of the Bonemass power, pair it with high-tier armor and healing items. For example, wear Wolf Armor or Padded Armor to further reduce incoming damage, and carry Healing Mead or Cooked Serpent Meat for quick health regeneration. Additionally, consider using a shield to block attacks, as the damage reduction from the Bonemass power stacks with the shield''s blocking ability, making you nearly invincible to physical damage.\n\nOne common challenge players face is managing the 20-minute cooldown of the Bonemass power. To address this, plan your engagements carefully and avoid unnecessary fights while the power is on cooldown. If you''re exploring a dangerous biome like the Plains or Mountains, wait for the cooldown to reset before venturing further. Alternatively, use other strategies like kiting enemies or building defensive structures to buy time until the power is available again.\n\nIn summary, the Bonemass power is a game-changer for tanking damage in Valheim, especially during boss fights or high-stakes encounters. By understanding its mechanics, timing its activation, and pairing it with the right gear and items, you can significantly improve your survivability. Whether you''re a new player tackling your first boss or an experienced Viking exploring the Plains, the Bonemass power is an essential tool in your arsenal.
