Kall Fimbulbringer is the final boss of Valheim — added with the Deep North biome in the 1.0 release. Beating it ends the Viking journey that started with Eikthyr and rolls the credits. It’s a long, three-phase fight with a very specific damage profile, so going in with the wrong weapons will get you nowhere. Here’s exactly how the fight works and what to bring, with numbers pulled straight from the 1.0 game data.
Before you go: you need to have beaten Fader
The Deep North sits after the Ashlands in progression. Unlike the Ashlands, it isn’t walled off by a boiling ocean — it gates you by sheer creature difficulty. You’ll want to have defeated Fader (the Ashlands boss) and be geared in Flametal or, ideally, the new Deep North gear before you attempt Kall Fimbulbringer. You reach the boss through the Deep North’s Jotun invasion event — activating the Orb of Fimbulvinter.
Kall Fimbulbringer HP: a three-phase fight
This is one of the longest boss fights in Valheim. Kall Fimbulbringer has three phases with separate health pools:
| Phase | Health |
|---|---|
| Phase 1 | 10,000 HP |
| Phase 2 | 7,000 HP |
| Phase 3 | 30,000 HP |
| Total | ~47,000 HP |
For comparison, that’s nearly double Fader’s 25,000 and more than twice The Queen’s 18,000 — so bring plenty of food and stamina meads and be ready for a marathon.
The key to the fight: use BLUNT or SLASH — not elemental
This is the mistake that wrecks most first attempts. Kall Fimbulbringer resists nearly every damage type:
- Resistant to: pierce, fire, frost, and lightning
- Immune to: spirit
- Takes full damage from: blunt and slash only
That means your shiny new Frostfire and Thunderblood weapons — which pile on fire, frost and lightning — are actually a worse choice here, because the elemental portion of their damage is resisted. Your best options are pure physical:
- Nord Sledge (200 blunt) or Thunderblood Sledge (235 blunt) — blunt lands in full
- Nord Greatsword / Nord Sword — high slash
- Nord Mace (170 blunt)
Check the full damage breakdown for every option in our Valheim weapons database — filter to the Deep North tier and sort by blunt/slash.
What to bring
- Weapon: a high-blunt Sledge or a slash Greatsword (see above)
- Food: the best 3-food loadout you can cook — use our Valheim food calculator and pick the Tank preset for max HP, plus the new Deep North dishes (Seal Meat Soup, Smoked Moose Meat)
- Meads: stamina and healing meads — 47,000 HP takes time, and you’ll be swinging heavy weapons constantly
- Armor: the new Deep North armor sets, or Flametal as a fallback
Beating it: the ending of Valheim
When Kall Fimbulbringer falls it drops Sacrificial Blood. Take it back to the Sacrificial Stones — the very first altar in the Meadows where your journey began — and offer it to complete the game and roll the credits. It’s the intended finale of Valheim’s whole progression arc, complete with new end-game cinematics.
