How do you unlock the ability to craft Frostner, and what materials are needed?

To unlock the ability to craft Frostner, one of Valheim''s most powerful maces, you must first progress through the game''s crafting tiers and defeat specific bosses. Frostner is a late-game weapon that combines frost, spirit, and blunt damage, making it highly effective against certain enemies. The crafting process requires access to advanced materials and a Forge upgraded to at least level 3. Below is a detailed guide on how to unlock Frostner and gather the necessary materials.\n\nFirst, you must defeat Bonemass, the third boss in Valheim, located in the Swamp biome. Bonemass drops the Wishbone, a key item that allows you to locate silver veins in the Mountains biome. Silver is a critical resource for crafting Frostner, as it is used to create Silver bars. To find silver, equip the Wishbone and explore the Mountains biome. When you are near a silver vein, the Wishbone will emit a pulsing sound and green particles. Dig down to uncover the vein and mine it using an Iron pickaxe or better.\n\nOnce you have gathered enough Silver ore, smelt it into Silver bars using a Blast Furnace. The Blast Furnace requires Artisan Table access, which is unlocked by defeating Moder, the fourth boss in the Mountains biome. Moder drops Dragon Tears, a resource needed to craft the Artisan Table. This step is essential for progressing to advanced crafting tiers and unlocking Frostner.\n\nNext, you will need Ancient Bark, which is obtained by chopping down Ancient Trees in the Swamp biome. These trees are large and require a Bronze or better axe to harvest. Ancient Bark is a versatile material used in many late-game recipes, including Frostner. Additionally, you will need Ymir Flesh, a rare material sold by Haldor, the merchant found in the Black Forest biome. Haldor requires coins for his items, so ensure you have enough currency from exploring dungeons or defeating enemies.\n\nFinally, Frostner requires Freeze Glands, which are dropped by Drakes in the Mountains biome. Drakes are flying creatures that can be challenging to defeat, especially in cold environments. Equip a bow and arrows to take them down from a distance, and bring Frost Resistance Mead to survive the freezing temperatures. Once you have all the materials, head to a Forge upgraded to level 3 or higher to craft Frostner.\n\nFrostner is particularly effective against enemies weak to frost and spirit damage, such as Bonemass and Fulings. Its frost effect slows enemies, making it easier to control crowds and deal consistent damage. However, it is less effective against creatures resistant to frost, such as Wolves and Lox. Always consider your enemy''s weaknesses when choosing your weapon.\n\nFor new players, progressing to Frostner may seem daunting, but focusing on upgrading your gear and defeating bosses in order will make the process manageable. Experienced Vikings can optimize their resource gathering by setting up portals near key biomes like the Swamp and Mountains. This reduces travel time and allows for efficient farming of materials.\n\nIn summary, unlocking Frostner requires defeating Bonemass and Moder, gathering Silver, Ancient Bark, Ymir Flesh, and Freeze Glands, and upgrading your Forge. This powerful mace is a valuable addition to your arsenal, especially in late-game scenarios. Plan your resource gathering carefully, and use Frostner strategically to maximize its effectiveness in combat.
