Valheim Progression Guide (2026): Boss Order, Biomes & Best Gear
Checked on 14 October 2026 against the Valheim 1.0.17 game files, including the Deep North and its boss, Kall Fimbulbringer, which arrived with 1.0 on September 9, 2026. The biome itself is covered on the Deep North vs Ashlands and Deep North biome prep pages.
Valheim is gated by biomes and bosses: each biome unlocks the metal and gear you need to survive the next, and each boss you beat drops a trophy that you hang on the Sacrificial Stones at the spawn to unlock its Forsaken Power, which you swap based on what's ahead. Follow this order and you'll never be under-geared.
The full order: biome → boss → gear
| # | Biome | Boss | Key gear to craft | Forsaken Power |
| 1 | Meadows | Eikthyr | Flint tools/weapons, Leather armor | Running, jumping and swimming cost 60% less stamina |
| 2 | Black Forest | The Elder | Bronze weapons, Bronze/Troll-hide armor | 60% more chopping and mining damage, 30% faster health regeneration |
| 3 | Swamp | Bonemass | Iron weapons (mace/sword), Iron armor, Root armor (archers) | 25% less blunt, slash and pierce damage, and blocking costs no stamina |
| 4 | Mountains | Moder | Silver weapons (Frostner, Draugr Fang bow), Wolf/Fenris armor | Tailwind while sailing, 300 more carry weight, 10% faster movement, half frost damage |
| 5 | Plains | Yagluth | Black-metal weapons, Padded armor | 10% more damage of every type, 25 extra Farming skill levels, half lightning damage |
| 6 | Mistlands | The Queen | Carapace gear, or Eitr-weave robes + magic (Eitr unlocked) | Twice the Eitr regeneration, sneaking costs no stamina, half poison damage |
| 7 | Ashlands | Fader | Flametal weapons & armor (bring Fire Resistance + best food) | Half fire damage, staggered half as fast, adrenaline builds twice as fast |
| 8 | Deep North | Kall Fimbulbringer | Nord and Frostfire weapons, Protector, Vanguard and Caller armour (Bloodgold) | None: he has no stone at the spawn |
How to use this
- Don't skip biomes. Each boss hands you the way into the next stage. The Elder drops the Swamp Key, one for every player on the server, which opens the Sunken Crypts; their muddy scrap piles give iron even to an Antler Pickaxe, while silver in the Mountains needs an Iron Pickaxe.
- Swap Forsaken Powers for the task: Eikthyr for grinding/running, Moder when sailing, Yagluth/Bonemass for tough fights. Every power lasts 5 minutes, and you can use it again 20 minutes after you activated it.
- Best food matters more than gear later. Three high-tier foods (max HP + stamina) carry the Plains/Mistlands/Ashlands more than a marginal weapon upgrade.
- Ashlands needs Fire Resistance before you set foot on the lava: the Fire Resistance Barley Wine halves fire damage for 10 minutes, and Fader's power does the same once he is beaten.
Best weapon by stage (quick reference)
| Stage | Standout weapon |
| Black Forest | Bronze Atgeir / Bronze Mace |
| Swamp | Iron Mace (vs Bonemass + skeletons), Iron Sword |
| Mountains | Frostner (mace), Draugr Fang (bow) |
| Plains | Black-metal Sword / Black-metal Atgeir |
| Mistlands | Carapace weapons, or staffs (Eitr magic) |
| Ashlands | Flametal weapons |
| Deep North | Nord weapons (Nord Sword 170 slash, Nord Sledge 225 blunt), then their Frostfire or Thunderblood versions |
The Deep North and Kall Fimbulbringer
The last stage, as the 1.0.17 game files set it up:
- Bloodgold is the new metal: smelt Petrified Tissue in the Blast Furnace. Petrified Tissue comes from Bloodgold veins and frozen troll remains, and no pickaxe is strong enough for them: the veins need tool tier 5, the troll remains tier 6, and the best pickaxe, Black Metal, is tier 3. Blast them with Ember Charges, whose explosion is tier 6. A Workbench makes 10 charges from 2 Seal Pelts and 1 Embers.
- Nord weapons need a level 4 Black Forge, Bloodgold, the weapon's mould and Timberwood (a Frozen Branch for the greatsword). Each can then be upgraded at the same forge in one of two ways: Frostfire Essence swaps some of the physical damage for 88 frost and 12 fire, and Thunderblood Essence plus 20 Bloodgold adds lightning (the Thunderblood Sword hits for 180 slash and 45 lightning, against 170 slash on the Nord Sword).
- Armour: the Protector set (heavy, 44 armour per piece before upgrades) and the Vanguard set (medium, 34) come from the level 4 Black Forge; the Caller set (mage, 22) from a level 3 Galdr Table.
- The summon: Kall Fimbulbringer waits in the Deep North boss room, which has two Strange Bowls that each take 3 Malicious Blood: one breaks the gate, the other summons him. Malicious Blood drops when you destroy Malicious Ice, the dark ice cores that keep spawning Krigen and Hexen while players are within 120 m. A core has 1,000 health, takes extra damage from chopping, mining and fire, and shrugs off half of any frost or lightning.
- The fight has three phases with 10,000, 7,000 and 30,000 health. In the second he calls up aspects of the seven earlier bosses, from the Aspect of the Lightning Stag to the Aspect of the Emerald Flame. His final form drops Sacrificial Blood and the Crown Jewel, which a level 4 Black Forge turns into the Crown of Valheim (50 armour) with Bloodgold.
