How can players use the hammer’s secondary attack in boss fights?

The hammer’s secondary attack in Valheim is a powerful tool during boss fights, especially when used strategically in co-op play. This attack, known as the ''slam,'' deals area-of-effect (AoE) damage and can stagger enemies, making it invaluable for crowd control and supporting teammates. To perform the secondary attack, players must equip a hammer (such as the Iron Sledge or Stagbreaker) and hold down the right mouse button to charge the attack, then release it to unleash a powerful slam.\n\nIn boss fights, the hammer’s secondary attack shines when dealing with adds—smaller enemies that spawn during the fight. For example, during the Bonemass fight in the Swamp biome, the boss summons Blobs and Skeletons. A well-timed hammer slam can clear these adds, allowing your team to focus on the boss. This is particularly useful for melee players who can protect ranged teammates from being overwhelmed.\n\nTo maximize the hammer’s effectiveness, players should position themselves strategically. Stand near teammates who are drawing the boss’s attention, and wait for adds to cluster together before using the slam. This ensures maximum damage and stagger potential. Additionally, the hammer’s AoE damage can hit multiple targets, making it ideal for fights like Moder in the Mountains, where Drakes and Wolves often swarm players.\n\nCrafting the right hammer is crucial for success. The Iron Sledge, for example, requires a Forge, 10 Iron, 4 Ancient Bark, and 1 Ymir Flesh. This weapon has high knockback and stagger potential, making it a top choice for boss fights. Alternatively, the Stagbreaker, crafted with 20 Core Wood, 5 Deer Trophies, and 2 Leather Scraps, is an early-game option that still provides decent AoE damage.\n\nOne common challenge during boss fights is managing stamina. The hammer’s secondary attack consumes a significant amount of stamina, so players should always carry stamina-boosting foods like Serpent Stew or Turnip Stew. Additionally, timing is key—use the slam when you have a clear opportunity, and avoid spamming it to prevent running out of stamina at critical moments.\n\nFor co-op teams, communication is essential. Designate one player as the hammer user to focus on adds, while others handle the boss. This division of labor ensures that the team remains organized and efficient. For example, during the Elder fight in the Black Forest, the hammer user can clear Greydwarfs while archers and melee fighters focus on the boss.\n\nFinally, practice makes perfect. Before engaging in a boss fight, test the hammer’s secondary attack on smaller enemies to get a feel for its range and timing. This will help you anticipate when and where to use it during the actual fight. With the right strategy and teamwork, the hammer’s secondary attack can turn the tide of any boss battle in Valheim.\n\nPractical tips: Always carry stamina food, position yourself near adds, and communicate with your team. Craft the Iron Sledge or Stagbreaker for optimal performance, and practice your timing to maximize the hammer’s potential.
