With the Deep North, Valheim’s map is now complete. But a new biome also means a new boss. In this frosty region you must face Valheim’s very last boss: Kall Fimbulbringer. This fight is a true test and will demand everything from you! You need to be extremely well prepared to prove yourself against the Frozen King. First, though, you have to summon him, which isn’t easy either. In this guide, we’ve summed up everything you need to know for Valheim’s finale. Naturally, this contains spoilers—if you want to experience it yourself, play it first.
Valheim Final Boss Kall Fimbulbringer: Location, Summoning, and Preparation
Before you can take on the fight, you first need to find and summon the boss. You need two things. First, you must find the Aesir Passage to reach the prison where Kall Fimbulbringer is being held. Second, you must open this passage by offering three Malicious Blood.
Both require thoroughly exploring the new biome. You might stumble upon the passage and mark it on your map, but it’s even easier to visit the Mörkhalla dungeon. Alternatively, you can search the memorials in the Deep North. At both places you’ll find signposts that point to the location of the Aesir Passage and mark it on your map.
In front of the passage stands a strange bowl into which you must place three Malicious Blood. You can only obtain this item by triggering Jotunn invasions and destroying the black crystals there. First, break a Malicious Ice in the Mörkhalla dungeon to start an invasion at a random spot on your map. There, increased numbers of warriors and witches will spawn, and you’ll have to hold your ground. Destroy the black ice in the center to receive Malicious Blood. You must repeat this three times.
You don’t have to fight alone, because you’re stronger together! Rent a Valheim server and defeat the final boss together and face the game’s last boss with friends.
Best Gear for the Fight Against Kall Fimbulbringer
Now you can summon Kall Fimbulbringer—but how do you tackle the fight itself? After all, it’s the final boss and will push you to your limits. You’ll want to have all the essentials lined up to make it through.
- Armor: We recommend the Vanguard armor, as you should be agile and light.
- Weapon: A combo of North Shield and a sword, club, or knife. You need mobility and the ability to block damage.
- Weapon upgrade: As an upgrade we suggest Thunderblood, since the Frostfire upgrade offers little. Kall resists both elements. He also resists lightning, but the 0.2% extra damage based on missing HP is worth its weight in gold.
- Food: Ideally two dishes for more HP (Meat in Bread, Elk Meat, Seal Meat Soup) and one for more stamina (Oat Milk, Oatmeal, Pancakes).
- Mead: Both fire and frost resistance are extremely important.
- Forsaken Power: Depending on your playstyle, use Fader, Yagluth, or Eikthyr.
In the end, the build is up to you—use whatever you feel best with. You can also go with heavy weapons or even magic. Valheim offers many approaches.
Fight Against Kall Fimbulbringer: Tips, Phases, and Strategies
As soon as you pass through the Aesir Gate, you’ll face the boss. The key is to stay calm and not panic. The fight will take some time; it’s better to avoid unnecessary damage than to be overly aggressive. You’ll battle through three phases that get tougher each time. Kall Fimbulbringer has a total of 47,000 HP—almost twice as much as Fader.
Phase 1: Chain Attacks and Melee at Kall Fimbulbringer (10,000 HP)
In the first phase, Kall attacks directly, primarily with his chains. They have quite a long reach, so sidestep smartly. You’re best off staying close to him and circling. This phase lets you study his general behavior and learn his attacks.
Phase 2: All Valheim Bosses as Spirits in a Duel (7,000 HP)
Phase 2 is very different, as you can’t attack Kall directly at first. Instead, he summons spirits of all previous bosses, starting with Eikthyr and then the others in pairs. With two bosses at once, things can get chaotic, since they bring their regular move sets. Always focus first on the one you find harder.
Phase 3: Mastering AOE, Frost, and Fire Damage (30,000 HP)
In the final phase, Kall returns to the fight, stronger and more powerful than before. With 30,000 HP, the battle can drag on, so fight strategically. His phase-1 attacks are joined by new ones, such as a ground slam with AOE damage. He also deals frost and fire damage, where your meads come into play. He can even summon vines from the ground to attack you.
The best strategy is to wait for a clear opening, get a few hits in, then create distance again. Repeat until the battle ends. You should also have enough food left to heal up in between. This fight is a marathon that will ask everything of you.
Rewards After Victory: Crown of Valheim and Ending
After defeating Kall Fimbulbringer, you receive two items you’ve truly earned. He doesn’t grant a new Forsaken Power—he is the final boss, after all. You can, however, challenge him again by using three more Malicious Blood, this time in the bowl inside the prison.
Two items from Kall Fimbulbringer:
- Crown Jewel: Craft the Crown of Valheim from this and Bloodgold. It makes all enemies flee before you (except bosses) and reduces stamina consumption by 20%.
- Sacrificial Blood: Kall’s unique drop. Bring it back to where your adventure began. After that, you can complete Valheim’s story.
Conclusion: A Demanding Finale Against Kall Fimbulbringer in Valheim
The fight against Kall Fimbulbringer is a major challenge that tests all your knowledge in a final showdown. You must prepare thoroughly and master your own combat style to prevail. It’s vital to stay mobile so you can dodge his attacks. Protect yourself with mead and plenty of food. In the end, only players who proceed strategically and don’t rush will triumph. The reward is well worth it.
