How do you use the Bonemass power to reduce physical damage during fights?

The Bonemass power in Valheim is one of the most valuable abilities for surviving tough combat encounters, especially when facing enemies that deal heavy physical damage. To unlock this power, you must defeat Bonemass, the third boss in the game, located in the Swamp biome. Once defeated, you can activate the Bonemass power at any Forsaken Altar, which grants you a temporary buff that reduces physical damage by 50% for 5 minutes. This ability is particularly useful in boss fights, raids, or when exploring dangerous biomes like the Plains or Mountains.\n\nTo use the Bonemass power effectively, you must first ensure it is equipped. Open your inventory and navigate to the power selection menu, which is located near the top-right corner of the screen. Select the Bonemass icon to make it your active power. Once equipped, you can activate it by pressing the corresponding key (default is ''F''). Keep in mind that the power has a cooldown of 20 minutes, so timing is crucial. Use it strategically during intense battles or when you anticipate taking significant physical damage.\n\nOne of the best ways to maximize the Bonemass power is to combine it with high-tier armor and food buffs. For example, wearing Wolf Armor or Padded Armor from the Mountains and Plains biomes, respectively, will further reduce incoming damage. Pair this with high-health foods like Serpent Stew, Lox Meat Pie, or Blood Pudding to increase your survivability. This combination ensures you can withstand even the toughest enemies, such as Fulings or Stone Golems, while the Bonemass power is active.\n\nDuring boss fights, the Bonemass power can be a game-changer. For instance, when fighting Moder, the Mountain biome boss, her physical attacks can deal massive damage. Activating the Bonemass power before engaging her will significantly reduce the damage you take, allowing you to focus on dodging her frost attacks and dealing damage. Similarly, when facing Yagluth, the Plains biome boss, his melee strikes and meteor showers can be mitigated with the Bonemass power, giving you more time to heal or reposition.\n\nAnother practical use for the Bonemass power is during raids on your base. Events like the ''Fuling Horde'' or ''The Ground is Shaking'' can overwhelm unprepared players. By activating the Bonemass power, you can tank hits from multiple enemies while defending your structures. This is especially helpful if you are caught off guard or need to buy time to repair walls or heal.\n\nFor new players, it’s important to note that the Bonemass power requires a Trophy from the boss and 10 Withered Bones to summon. Withered Bones are found in Sunken Crypts within the Swamp biome, so be prepared to explore these dangerous areas. Bring Poison Resistance Mead and a strong weapon like an Iron Mace to deal with the Draugr and Blobs that inhabit the crypts.\n\nIn summary, the Bonemass power is a versatile tool for reducing physical damage in Valheim. Equip it before engaging in tough fights, pair it with strong armor and food buffs, and use it strategically during boss battles or raids. By mastering this power, you’ll significantly improve your chances of survival in the game’s most challenging encounters.
