How do you craft and use the Frostner hammer effectively?

The Frostner hammer is one of the most powerful weapons in Valheim, combining frost, spirit, and blunt damage to dominate enemies in the Mountain and Plains biomes. To craft Frostner, you need to unlock the Forge upgrade to level 3 and gather specific materials: 10 Ancient Bark, 30 Silver, 5 Ymir Flesh, and 5 Freeze Glands. Ancient Bark is obtained from Ancient Trees in the Swamp biome, Silver is mined in the Mountains using a Wishbone, Ymir Flesh is purchased from Haldor the merchant in the Black Forest, and Freeze Glands are dropped by Drakes in the Mountains.\n\nOnce crafted, Frostner excels in both melee combat and crowd control. Its frost damage slows enemies, making it easier to manage groups or kite tougher foes. The spirit damage is particularly effective against undead enemies like Skeletons and Draugr, while the blunt damage is ideal for dealing with heavily armored enemies such as Stone Golems or Fulings in the Plains. To use Frostner effectively, pair it with a strong shield like the Black Metal Shield to block incoming attacks while countering with Frostner''s powerful strikes.\n\nFrostner''s special ability, the frost effect, is a game-changer in combat. When you hit an enemy, it applies a slowing debuff, reducing their movement and attack speed. This makes Frostner especially useful against fast-moving enemies like Wolves in the Mountains or Fuling Berserkers in the Plains. For example, when fighting a pack of Wolves, Frostner''s slowing effect allows you to control the battlefield, preventing them from overwhelming you. Similarly, against Fuling Berserkers, the frost effect gives you time to dodge their heavy attacks and retaliate.\n\nTo maximize Frostner''s potential, upgrade it at the Forge using Silver and Ancient Bark. Each upgrade increases its damage and durability, making it even more effective in late-game scenarios. Additionally, consider pairing Frostner with food that boosts stamina, such as Serpent Stew or Bread, as its attacks consume stamina quickly. This ensures you can maintain a steady rhythm in combat without running out of energy.\n\nOne common challenge players face is managing stamina while using Frostner. To address this, practice timing your attacks and blocks efficiently. For example, against a Stone Golem, block its initial attack, then follow up with two or three Frostner strikes before retreating to regain stamina. This hit-and-run strategy minimizes risk while maximizing damage output.\n\nIn summary, Frostner is a versatile weapon that shines in the Mountains and Plains biomes. Its frost and spirit damage make it a top choice for dealing with undead and heavily armored enemies, while its slowing effect provides excellent crowd control. Craft it as soon as you have access to Silver and Ymir Flesh, and upgrade it to dominate late-game challenges. Pair it with a strong shield and stamina-boosting food to ensure you can handle any threat Valheim throws your way.
