Valheim Bosses in Order: All 8 Bosses and How to Summon Them

In Valheim you progress by defeating the bosses, known as the Forsaken. Each boss lives in its own biome, grants a special power and drops the material you need for the next biome. Valheim 1.0 (September 2026) added the eighth and final boss: Kall Fimbulbringer in the Deep North.

All bosses in order

To find a boss altar, look for Vegvisir stones: rune stones with a red glow. Interact with one and the boss location appears on your map.

Eikthyr (Meadows)

The first and easiest boss. Place 2 deer trophies on his altar. He attacks with lightning and charges, so keep your distance with a bow and flint arrows and dodge between his attacks.

Reward: the hard antler for the antler pickaxe, which mines copper and tin. His power reduces the stamina you use for running, jumping and swimming by 60%.

The Elder (Black Forest)

Summon him with 3 ancient seeds, which drop from greydwarf nests. He is a huge, slow tree and weak to fire: fire arrows work very well. Use the pillars in the arena as cover from his roots and ranged attacks.

Reward: the swamp key, which opens the sunken crypts in the Swamp. His power gives 60% more chopping and mining damage and 30% more health regeneration.

Bonemass (Swamp)

For many players the hardest boss of the first half of the game. You need 10 withered bones from the sunken crypts. He resists slash and pierce damage but is weak to blunt damage, so bring a mace. His poison hits hard: drink a poison resistance mead before the fight.

Reward: the Wishbone, which points you to silver veins in the Mountains. His power reduces pierce, slash and blunt damage by 25%, and blocking costs no stamina and returns 5 stamina per block.

Moder (Mountains)

Summon her with 3 dragon eggs from the mountain peaks. The eggs are heavy, so carry them one at a time. Moder flies and attacks with frost breath: drink a frost resistance mead and bring a good bow with obsidian or needle arrows.

Reward: dragon tears for the artisan table. Her power gives you a tailwind whenever you sail, plus 300 extra carry weight, 10% more movement speed and 50% frost resistance.

Yagluth (Plains)

You need 5 fuling totems from the fuling villages in the Plains. Yagluth throws fire and meteors, so bring your best gear and fire resistance. Keep moving and attack when he finishes a combo.

Reward: his power gives 50% lightning resistance, 25 extra points in the Farming skill and 10% more damage.

The Queen (Mistlands)

She waits inside the infested citadel. To get in, collect 9 Sealbreaker fragments in the infested mines, where they sit under glass on pedestals. Craft the Sealbreaker at the Galdr table and use it to open the citadel gate. The fight is long: bring Mistlands gear and plenty of healing.

Fader (Ashlands)

One of the toughest fights in the game. In the charred fortresses of the Ashlands you find 9 bell fragments, which you turn into 3 bells at the black forge. Place the bells at Fader's altar. Bring your best Ashlands gear and fire resistance.

Kall Fimbulbringer (Deep North, Valheim 1.0)

Kall Fimbulbringer arrived with Valheim 1.0 on 9 September 2026 as the boss of the Deep North. The 1.0 patch notes also list new items such as Malicious Blood, Sacrificial Blood, Crown Jewel and Intricate Key, plus the Mörkhalla dungeon and Jotun invasions. How these relate to summoning him and to his drops is not described in the patch notes, and as of 16 October 2026 the official wiki has no page on Kall yet.

What is confirmed: according to the wiki, snowstorms in the Deep North deal continuous freezing damage unless you wear frost resistant clothing or drink a Frost Resistance Mead, and according to patch 1.0.16 extra enemies spawn during the boss fight. Iron Gate recommends a new world for 1.0, because new biomes only generate properly in unexplored areas.

How to use boss powers

After a win you get the boss trophy. Hang it on its sacrificial stone in the starting area to unlock the power, then activate it with the power key (F by default). Only one power can be active at a time, and there is a cooldown after each use.

Bosses in multiplayer

Bosses are easier and more fun in a group, but they get stronger the more players are nearby. A few tips:

• Split the roles: someone with a shield draws the boss while the others attack with bows or blunt weapons.
• Prepare food and potions for everyone before you summon.
• Build a small shelter with a bed and workbench near the altar so you get back quickly after a death.

On a dedicated server the world is always online: everyone can prepare on their own time and the group meets up for the fight whenever it suits. World modifiers let you tune the difficulty to your group.
