How do you use the Frostner mace to deal frost damage to Bonemass?

The Frostner mace is one of the most effective weapons for fighting Bonemass, the third boss in Valheim, due to its frost damage and knockback capabilities. Bonemass is highly resistant to most physical damage types, but it is particularly weak to frost damage, making Frostner an ideal choice. To use Frostner effectively, you must first craft it, which requires materials like Silver, Ymir Flesh, and Freeze Glands, all of which are found in specific biomes.\n\nTo craft Frostner, you need to progress to the Mountain biome, where Silver can be mined using a Wishbone obtained from defeating the second boss, The Elder. Ymir Flesh is purchased from Haldor the merchant in the Black Forest, and Freeze Glands are dropped by Drakes in the Mountain biome. Once you have these materials, craft Frostner at a level 2 Forge. This weapon deals frost damage, which slows enemies and reduces their movement speed, making it particularly useful against Bonemass.\n\nBefore engaging Bonemass, prepare thoroughly. Equip Frostner and ensure you have a strong shield, such as the Iron Buckler or Silver Shield, to block its melee attacks. Wear upgraded Iron or Wolf Armor for maximum protection, and bring healing meads like Medium Healing Mead and Poison Resistance Mead, as Bonemass deals heavy poison damage. Additionally, clear the area around the Bonemass summoning altar to avoid distractions from other enemies during the fight.\n\nDuring the fight, focus on timing your attacks and blocks. Bonemass has three main attacks: a melee swipe, a poison cloud, and a summoning ability that spawns Blobs and Skeletons. Use Frostner''s frost damage to slow Bonemass and create openings for attacks. When Bonemass raises its arm for a melee swipe, block with your shield to reduce damage. Avoid standing in the poison cloud, as it deals significant damage over time. Use Frostner''s knockback to keep summoned enemies at bay while focusing on Bonemass.\n\nA common challenge is managing stamina during the fight. Bonemass is a tanky boss, so stamina management is crucial. Avoid spamming attacks and instead focus on landing precise hits with Frostner. Use the terrain to your advantage by kiting Bonemass around trees or rocks to create distance when needed. If you run out of stamina, retreat briefly to recover before re-engaging.\n\nAfter defeating Bonemass, you will receive the Wishbone, which is essential for finding Silver in the Mountain biome. This victory also unlocks the next stage of progression, allowing you to craft better gear and prepare for future challenges. Frostner remains a valuable weapon throughout the game, especially in the Plains biome, where its frost damage is effective against Fulings and other enemies.\n\nIn summary, Frostner is a powerful weapon for defeating Bonemass due to its frost damage and knockback effects. Craft it using Silver, Ymir Flesh, and Freeze Glands, and prepare thoroughly with strong armor, shields, and healing meads. During the fight, focus on timing your attacks, blocking Bonemass''s melee swipes, and avoiding its poison cloud. Manage your stamina carefully and use the terrain to your advantage. With these strategies, you can defeat Bonemass and progress further in Valheim.
