Valheim Deep North: Creatures, Resources and Hazards
Deep North biome reference: creature drops, Bloodgold and Frostcore uses, crafting stations, Winding Tunnels, Mörkhalla, and the route to Kall Fimbulbringer.
Reviewed 2026-09-19
Deep North is the final biome in Valheim's boss progression. This reference covers its creatures, material uses, dungeons, and survival preparation. For the workshop sequence and an expedition checklist, follow the Deep North guide.
Details below are cross-checked against community guides where Iron Gate's notes do not supply the mechanics.
Where Deep North fits
Deep North follows Ashlands and Fader. His Relic makes the Eternal Pyre that supplies Embers, used in the charges needed to harvest Petrified Tissue for Bloodgold. Bring that supply chain with you rather than expecting every ingredient to come from northern dungeons.
| Stage | Main destination |
|---|---|
| Previous | Ashlands and Fader |
| Current | Deep North: surface materials → Winding Tunnels → Mörkhalla |
| Finale | Jotun invasions → Aesir Passage → Kall Fimbulbringer |
See the progression roadmap for the earlier biomes.
Creatures
| Creature | Encounter and useful drops |
|---|---|
| Seal | Coastal wildlife; Seal Pelt and Seal Blubber |
| Moose | Tameable, rideable animal; Moose Meat, Hide, and Sinew |
| Gammeltroll | Large surface troll; its petrified remains yield Petrified Tissue when broken with an Ember Charge |
| Barka | Frozen tree-like enemy; Frozen Branch |
| Elaking | Winding Tunnels enemy; Intricate Key mould and Elaking Hair Bundle |
| Eyeless One | Winding Tunnels enemy; Long Claws |
| Krigen | Mörkhalla enemy; Leather Straps, Memorial Coal, and Vanguard armor moulds |
| Hexen | Mörkhalla enemy; Nornathread and Caller armor moulds |
| Fallen Warrior | Ancient Altar encounter; can drop Frostfire Essence and Thunderblood Essence |
These are the material drops most relevant to progression, not exhaustive loot tables. The official update also names several Pulp variants and Writhan; they are not assigned unverified drop tables here.
Resources
| Resource | Acquisition and use |
|---|---|
| Bloodgold | Smelt Petrified Tissue in a Blast Furnace; used in equipment and key casts |
| Frostcore | Gather in Winding Tunnels; needed to construct the Frigid Kiln and Frost Foundry |
| Ice / Liquid Frost | The Frigid Kiln converts 5 Ice to 1 Liquid Frost; the latter fuels the Frost Foundry |
| Frostfire Essence / Thunderblood Essence | Fallen Warrior rewards from Ancient Altars; used for the respective weapon upgrades |
| Memorial Coal | Collected from Krigen in Mörkhalla; offered at Ancient Altars to summon Fallen Warriors |
| Nornathread | Hexen drop; used in Caller armor and magical equipment |
| Seal Pelt / Embers | Combined into Ember Charges for breaking petrified Gammeltroll remains; Embers come from the Eternal Pyre |
| Frozen Branch | Barka drop; used in equipment such as the Nord Greatsword and Spirit Caller |
| Lingonberries | Harvestable food ingredient |
| Timberwood, Kale, Oats, Poteitr | Plantable resources listed in the 1.0 release |
The Black Forge makes casts from moulds and recipe materials. The Frost Foundry turns those casts into finished equipment or keys, using Liquid Frost from the Frigid Kiln. Smith's Aprons, Standing Loom, and Smoker extend the Black Forge, Galdr Table, and Cauldron respectively.
Boss: Kall Fimbulbringer
- Summon: offer 3 Malicious Blood in the Strange Bowl at the Aesir Passage to enter The Prison.
- Blood route: unlock Mörkhalla with Intricate Keys, break its Malicious Ice, then complete the resulting Jotun Invasion for one Blood. Repeat for three.
- Fight: three phases, including a middle gauntlet of earlier Forsaken Aspects while Kall is immune.
- Rewards: Sacrificial Blood and Crown Jewel; no Forsaken Power.

Building and survival tips
- Clear deep snow with a Snow Shovel before laying out an outpost.
- Watch slippery ice and frozen water. Keep a retreat route and stamina reserve when exploring the shoreline.
- Establish storage and a protected portal before long dungeon trips; keep a supply of Liquid Frost at your workshop so returning with a mould can lead straight to an upgrade.
- Check hotfix 1.0.10 if Deep North heavy armor cannot be repaired.
- For older saves, new biome generation requires unexplored terrain. Read the world migration guidance before heading north.
Points of interest
Winding Tunnels, reached beneath abandoned villages, provide Frostcores and key moulds. They are the preparation dungeon for your workshop and the next dungeon tier.
Mörkhalla requires an Intricate Key. Its enemies supply armor materials and moulds; its Vegvisir marks the Aesir Passage. Destroying the Malicious Ice at the bottom starts a Jotun Invasion elsewhere in the world. Breaking the invasion core yields Malicious Blood for the boss offering.
Ancient Altars turn Memorial Coal into Fallen Warrior encounters and a chance at weapon essences. Aesir Passage is the final destination once your three Blood and boss loadout are ready.
