How do you handle Bonemass’s poison attacks in co-op?

Bonemass, the third boss in Valheim, is notorious for its devastating poison attacks, which can quickly overwhelm unprepared players, especially in co-op. To handle Bonemass’s poison effectively, you need to prepare thoroughly, coordinate with your team, and use specific strategies to mitigate the damage. This guide will walk you through the mechanics of Bonemass’s poison attacks and provide step-by-step instructions for surviving and defeating this challenging boss in co-op mode.\n\nFirst, understand Bonemass’s poison mechanics. Bonemass has two primary poison-based attacks: a close-range poison cloud and a ranged poison projectile. The poison cloud is emitted when Bonemass slams the ground, creating a toxic area that lingers for several seconds. The ranged attack is a lobbed poison blob that explodes on impact, spreading poison in a small radius. Both attacks deal significant damage over time and can stack, making them deadly if not managed properly.\n\nPreparation is key to surviving Bonemass’s poison. Before the fight, ensure all players have Poison Resistance Mead, crafted at a Fermenter using Honey, Thistle, Neck Tail, and Coal. This mead reduces poison damage by 75% for 10 minutes, making it essential for the fight. Additionally, equip armor with high poison resistance, such as the Root Mask from the Swamp biome, which provides a passive poison resistance bonus. Stock up on healing items like Cooked Meat, Sausages, and Health Mead to sustain yourself during the battle.\n\nDuring the fight, positioning and teamwork are critical. Assign roles to each player, such as a tank to draw Bonemass’s attention and ranged attackers to deal damage from a safe distance. The tank should stay close to Bonemass to bait its melee attacks, while ranged players should avoid standing in the poison cloud or near the poison blobs. Use the terrain to your advantage by fighting near large trees or rocks, which can block the poison projectiles.\n\nTo counter the poison cloud, always move out of the area immediately after Bonemass slams the ground. If you’re caught in the cloud, use your Poison Resistance Mead and healing items to mitigate the damage. For the poison blobs, keep an eye on Bonemass’s animation—it raises its arm before throwing the projectile. When you see this, dodge roll or move out of the way to avoid the explosion.\n\nCommunication is vital in co-op. Use voice chat or text to alert your team when Bonemass is about to use a poison attack. For example, call out “Poison cloud incoming!” or “Dodge the blob!” to ensure everyone reacts quickly. If a teammate is poisoned, prioritize healing them with Health Mead or other items to prevent them from being overwhelmed by the damage over time.\n\nFinally, focus on dealing consistent damage while managing the poison. Use Frostner, a powerful mace crafted with Silver, Ymir Flesh, and Ancient Bark, as it deals bonus damage to Bonemass and slows its movement. Alternatively, use arrows or other blunt weapons if Frostner isn’t available. Keep the fight organized and avoid panicking, as Bonemass’s attacks are predictable once you understand its patterns.\n\nIn summary, handling Bonemass’s poison attacks in co-op requires preparation, coordination, and quick reactions. Equip Poison Resistance Mead, assign roles, use the terrain, and communicate effectively to minimize poison damage. With these strategies, you and your team can overcome Bonemass and claim its trophy, unlocking the next stage of your Valheim adventure.
