How do you use the Bonemass power against Yagluth?

Using the Bonemass power against Yagluth, the final boss in Valheim, is a highly effective strategy due to its damage reduction capabilities. The Bonemass power reduces all physical damage taken by 75% for 5 minutes, which is invaluable during Yagluth''s intense combat. To activate this power, you must first defeat Bonemass in the Swamp biome and place its trophy on the sacrificial stone at your spawn point. Once activated, the power can be used once every 20 minutes, so timing is crucial.\n\nBefore engaging Yagluth, ensure you are fully prepared. Craft the best armor available, such as Padded Armor, and upgrade it to the highest level. Equip a strong melee weapon like the Blackmetal Sword or Frostner, as well as a powerful bow like the Draugr Fang for ranged attacks. Stock up on healing meads, stamina meads, and fire resistance barley wine, as Yagluth deals heavy fire damage. Fire resistance is particularly important because Yagluth''s attacks include fire-based AoE (area of effect) damage.\n\nWhen you arrive at Yagluth''s summoning altar in the Plains biome, clear the area of Fulings, Deathsquitos, and other hostile creatures to avoid distractions during the fight. Place a portal nearby for quick access in case you need to retreat or resupply. Summon Yagluth by placing five Fuling Totems on the altar, and immediately activate the Bonemass power as the fight begins. This will give you the damage reduction buff for the first critical phase of the battle.\n\nDuring the fight, Yagluth uses a combination of melee attacks, fire breath, and meteor showers. The Bonemass power will significantly reduce the damage from his melee strikes, allowing you to focus on dodging his fire-based attacks. Stay mobile and avoid standing in fire patches or meteor impact zones. Use your bow to deal damage from a distance when Yagluth is using his fire breath, and switch to melee when he pauses between attacks.\n\nOne common challenge is managing stamina during the fight. Yagluth''s attacks are relentless, and running out of stamina can leave you vulnerable. To mitigate this, use stamina meads and avoid unnecessary sprinting. Focus on timed dodges and blocks to conserve stamina while maintaining pressure on Yagluth. If you run low on health, retreat to a safe distance and use healing meads or food like Serpent Stew or Lox Meat Pie to recover.\n\nAfter the Bonemass power expires, you will need to rely on your armor and fire resistance to survive. Keep an eye on the cooldown timer for the Bonemass power, and reactivate it as soon as it becomes available. This will ensure you have consistent damage reduction throughout the fight. If you die during the battle, use your nearby portal to return quickly and continue the fight without losing progress.\n\nIn summary, the Bonemass power is a game-changer when fighting Yagluth. Its damage reduction allows you to withstand his powerful attacks, giving you the edge needed to defeat the final boss. Combine this with proper preparation, fire resistance, and strategic use of meads to maximize your chances of success. With patience and persistence, you can conquer Yagluth and complete your Valheim journey.
