Valheim's bosses gate your progression. The first seven are the Forsaken: each one drops a trophy that unlocks a Forsaken power at the Sacrificial Stones, plus a material you need for the next step. Valheim 1.0, released on 9 September 2026, added an eighth and final boss in the Deep North, Kall Fimbulbringer (Iron Gate lists him in the 1.0 patch notes). Here is every boss in order, how to summon it, and how to win.
Boss Order
| # | Boss | Biome | Summon Item |
|---|---|---|---|
| 1 | Eikthyr | Meadows | 2 Deer Trophies |
| 2 | The Elder | Black Forest | 3 Ancient Seeds |
| 3 | Bonemass | Swamp | 10 Withered Bones |
| 4 | Moder | Mountains | 3 Dragon Eggs |
| 5 | Yagluth | Plains | 5 Fuling Totems |
| 6 | The Queen | Mistlands | Sealbreaker to open her citadel, then 3 Seeker Soldier Trophies for a rematch |
| 7 | Fader | Ashlands | 3 Bells |
| 8 | Kall Fimbulbringer | Deep North | 3 Malicious Blood |
1. Eikthyr (Meadows)
A stag with lightning attacks. Summon him at his altar in the Meadows with 2 Deer Trophies. Use a bow and dodge his lightning AoE. Drop: Hard Antler (lets you craft the Antler Pickaxe) and a power that reduces stamina drain while running, jumping and swimming.
2. The Elder (Black Forest)
A giant tree creature. Find his location with Vegvisir runestones in Burial Chambers. Summon with 3 Ancient Seeds from Greydwarf nests. Use fire arrows, he is weak to fire. Dodge his root attacks and stomp. Drop: Swamp Key (opens Sunken Crypts) and a power that boosts wood chopping.
3. Bonemass (Swamp)
A blob of poison. Summon with 10 Withered Bones from Sunken Crypts. Use a blunt weapon (Iron Mace), he resists most damage but is weak to blunt. Bring poison resistance mead. Drop: Wishbone (finds buried treasure) and a power for physical damage resistance. Our Bonemass guide covers his altar, attacks and the gear to bring.
4. Moder (Mountains)
A dragon. Summon with 3 Dragon Eggs from the Mountains. Fight on open ground, use frost-resistance mead, and shoot her with arrows when she lands. Drop: Dragon Tears (craft the Artisan Table) and a power for tailwind sailing. Our Moder guide covers finding her altar, carrying the eggs and each attack.
5. Yagluth (Plains)
A giant undead. Summon with 5 Fuling Totems from Fuling villages. Dodge his meteor and fire-beam attacks. Drop: three Torn Spirits and his trophy. You need a Torn Spirit to build the Wisp Fountain, which is how you get the Wisplight for the Mistlands. His power gives lightning resistance, +25 Farming and 10% more damage. Our Yagluth guide covers finding his altar, each attack and the gear to bring.
6. The Queen (Mistlands)
She lives inside the Infested Citadel, a sealed Dvergr vault in the Mistlands. Vegvisirs in Infested Mines point you to it. Collect 9 Sealbreaker Fragments from the glass displays in Infested Mines and craft the Sealbreaker at the Galdr Table. It opens the vault door and is not used up.
The first fight needs no offering, because she is already inside. For a rematch, offer 3 Seeker Soldier Trophies at the hive seat at the top of the citadel. She teleports around the arena, calls in Seekers and broods, and spits poison, so bring poison resistance and your Mistlands gear. The covered area at the entrance is out of reach of her own attacks (her broods can still follow you in), which makes it the place to heal. Drop: Majestic Carapace (for the Artisan Press) and her trophy. Her power speeds up Eitr regeneration and gives poison resistance.
7. Fader (Ashlands)
The Ashlands boss. You summon him by placing 3 Bells around his altar, a coliseum-like structure in the Ashlands. Each Bell is crafted at the Black Forge from 3 Bell Fragments, which sit on altars in the towers of Charred Fortresses, and the Vegvisirs in those fortresses point to his altar. Bring Flametal-tier gear and fire resistance. Drop: Kindled Ribs and his trophy. Kindled Ribs build the Eternal Pyre, whose Embers you craft into Ember Charges and the Snow Shovel for the Deep North. That makes Fader the real gate to the last biome. His power gives fire resistance and doubles the adrenaline that powers your trinkets.
8. Kall Fimbulbringer (Deep North)
The last boss, added in Valheim 1.0. Getting to him is a small quest of its own:
- Make an Intricate Key (a Bloodgold cast hardened in the Frost Foundry) and use it to open a Mörkhalla dungeon.
- Destroy the Malicious Ice on Mörkhalla's bottom floor. That starts a Jotun Invasion somewhere in the earlier biomes.
- Find the invasion and destroy the Malicious Ice at its centre for one Malicious Blood. You need three.
- Find an Aesir Passage in the Deep North (Vegvisirs at Memorial Sites and in Mörkhalla show the way) and offer the three Malicious Blood at the Strange Bowl there.
The fight has three phases. In the first he swings his chains at you. In the second he hides in a block of ice that nothing can damage, while spirits of the seven earlier bosses come after you; every spirit you kill takes a chunk off his health. In the third he fights you directly again with stronger attacks, and summons tendrils that shoot lightning. He resists pierce, fire, frost and lightning, is immune to spirit damage and cannot be staggered, so arrows and elemental staves do less than you are used to.
Drop: Sacrificial Blood, which you need for the game's ending, and a Crown Jewel for the Crown of Valheim. Sacrificial Blood cannot go through any portal, so plan a last boat trip. Unlike the seven Forsaken, he gives no Forsaken power. The Valheim Wiki's Kall Fimbulbringer page has the full numbers for every attack.
Multiplayer Boss Fights
Bosses scale in difficulty and are much easier with friends. Running a dedicated Valheim server, for example with our Valheim server hosting, lets your group progress together without one person needing to host. Allocate at least 4 GB RAM for a small group.
