Deep North

The Deep North is the frozen northern edge of every valheim world and, since the 1.0 release on September 9, 2026, the final biome and the end of progression. It is gated behind the Ashlands: you cannot make headway here until Fader is dead.

What's Here

Bloodgold, the metal every Deep North weapon and armor set is cast from, plus Frostcores and the moulds that make them usable. The roster runs Seals, Elaking, Moose, Eyeless Ones, Barka, and the 3,000 HP Gammeltroll. Nearly everything here is weak to fire.

The Bloodgold Loop

Gammeltrolls petrify into terrain when killed, so a pickaxe is useless on them. Adult Seals drop Seal Pelts, and 1 Ember plus 2 Seal Pelts crafts a stack of 10 Ember Charges at a Workbench. Those charges break the statue into Petrified Tissue, which smelts with Coal in a Blast Furnace into Bloodgold.

Dungeons and the Boss

Winding Tunnels hold Frostcores and the Mould: Intricate Key. The key opens the Gates of Mörkhalla, where three Jotun invasions yield the 3 Malicious Blood that summon Kall Fimbulbringer, the highest-health boss in the game. It resists fire, pierce, frost and lightning, so bring blunt or slash.

Full progression order, creature HP table and armor values are in the Deep North guide. The final fight has its own page: Kall Fimbulbringer.
