How can I use Frostner effectively against Bonemass?

Frostner is one of the most effective weapons to use against Bonemass in Valheim due to its frost and spirit damage, which are highly effective against this boss. Bonemass is weak to frost damage, and Frostner''s secondary attack can slow it down, making the fight more manageable. To craft Frostner, you need to progress to the Mountain biome, gather silver ore, and craft it at a level 3 Forge. You will also need Ymir Flesh, which is purchased from Haldor the merchant in the Black Forest, and Ancient Bark from the Swamp biome.\n\nBefore engaging Bonemass, ensure you are well-prepared. Equip a full set of Iron Armor or better, as Bonemass deals heavy melee damage. Bring healing meads, stamina meads, and poison resistance meads, as Bonemass uses poison attacks that can quickly drain your health. Additionally, clear the area around the Bonemass summoning altar to avoid distractions from other enemies in the Swamp biome.\n\nDuring the fight, focus on Frostner''s secondary attack, which deals frost damage and slows Bonemass. This attack has a wide arc, making it easier to hit Bonemass while maintaining distance. Use the terrain to your advantage by kiting Bonemass around trees, rocks, or the altar itself. This will help you avoid its melee attacks and give you time to recover stamina.\n\nBonemass will periodically summon adds, such as skeletons and blobs. Use Frostner''s primary attack to quickly dispatch these enemies, as they can overwhelm you if left unchecked. Frostner''s spirit damage is particularly effective against skeletons, making it a versatile weapon for this fight. Keep an eye on your stamina and health, and use meads as needed to stay in the fight.\n\nOne common challenge is managing stamina while using Frostner''s secondary attack, as it consumes a significant amount. To mitigate this, use stamina meads and avoid spamming the attack. Instead, time your attacks carefully, focusing on hitting Bonemass when it is close and retreating when it prepares to attack. This hit-and-run strategy will help you conserve stamina and avoid unnecessary damage.\n\nAnother tip is to use a shield alongside Frostner. While Frostner is a two-handed weapon, you can quickly switch to a shield to block Bonemass''s melee attacks if you find yourself in a tight spot. This can be a lifesaver if you misjudge your positioning or run out of stamina.\n\nFinally, consider bringing a bow and frost arrows as a backup. While Frostner is your primary weapon, frost arrows can deal additional frost damage from a distance, allowing you to chip away at Bonemass''s health while staying safe. This is especially useful if you need to create distance or deal with adds without getting too close.\n\nIn summary, Frostner is an excellent choice for the Bonemass fight due to its frost and spirit damage. Prepare thoroughly with the right gear, meads, and terrain knowledge. Use Frostner''s secondary attack to slow Bonemass and manage adds efficiently. With careful stamina management and strategic positioning, you can defeat Bonemass and progress further in Valheim.
