What is the best way to use the Bonemass power for survivability?

The Bonemass power is one of the most effective tools for survivability in Valheim, especially when facing the final boss, Yagluth. This power reduces all physical damage by 50% for 5 minutes, making it invaluable during intense combat scenarios. To unlock the Bonemass power, you must defeat the Bonemass boss in the Swamp biome and place its trophy on the corresponding altar at spawn. Once activated, the power can be used once every 20 minutes, so timing is crucial.\n\nTo maximize the Bonemass power''s effectiveness against Yagluth, you should activate it just before engaging the boss. Yagluth deals significant physical damage with his melee attacks and meteor strikes, so the damage reduction is critical. Pair this power with high-tier armor, such as Padded Armor, which is crafted using Linen Thread and Iron. This combination ensures you can withstand Yagluth''s relentless assaults while dealing consistent damage.\n\nPreparation is key when using the Bonemass power. Before the fight, stock up on healing items like Medium Healing Mead and stamina-boosting foods such as Serpent Stew or Lox Meat Pie. These consumables will help you maintain your health and stamina during the prolonged battle. Additionally, bring a strong melee weapon like the Blackmetal Sword or Frostner, as Yagluth is resistant to fire and poison but vulnerable to frost damage.\n\nDuring the fight, stay mobile to avoid Yagluth''s area-of-effect attacks. Use the Bonemass power to tank his melee strikes, but don''t rely solely on it. Keep an eye on the power''s cooldown timer and retreat to a safe distance if it expires. Use this time to heal and reposition yourself. If you''re playing with a group, coordinate with your teammates to stagger the use of Bonemass powers, ensuring continuous damage reduction throughout the fight.\n\nOne common challenge is managing stamina while using the Bonemass power. Since Yagluth''s attacks are relentless, you may find yourself running low on stamina. To counter this, use stamina-boosting foods and avoid unnecessary sprinting. Focus on blocking and parrying his attacks to conserve stamina while dealing damage. A well-timed parry can stagger Yagluth, giving you a window to unleash a flurry of attacks.\n\nFinally, consider the environment when fighting Yagluth. The Plains biome is open, but you can use natural terrain features like rocks and hills to block his line of sight or create temporary cover. Building a small outpost nearby with a portal and workbench can also provide a quick escape or resupply point if needed. Remember, the Bonemass power is a tool, not a crutch—use it strategically to turn the tide in your favor.\n\nIn summary, the Bonemass power is a game-changer for survivability against Yagluth. Combine it with high-tier armor, frost-based weapons, and stamina-boosting foods to maximize its effectiveness. Stay mobile, manage your stamina, and use the environment to your advantage. With proper preparation and timing, you can overcome Yagluth and claim victory in Valheim.
