Frostner is one of the most powerful weapons in Valheim. The combination of Frost and Spirit damage makes Frostner effective against most enemies. Even players that don’t use clubs may find it worthwhile to make Frostner because it’s one of the most effective weapons against Yagluth.
You will need to make a trip to Haldor the Trader to purchase the Ymir Flesh needed to craft Frostner. It’s one of the few items in the game that requires Ymir Flesh.

The spirit damage applied by Frostner burns enemies with spirit fire which is particularly effective against undead such as Skeletons, Draugr, Wraiths, etc.
Frostner will surround you with a frosty aura. These are simply particle effects and are only aesthetic.
