Valheim Bosses: All Eight Forsaken, What They Resist and How to Summon Them
Valheim 1.0 has eight bosses, one per biome, from Eikthyr in the Meadows to Kall Fimbulbringer in the Deep North. Each one is summoned at its own altar with items from its biome, and each drops what you need to move on. Every number on this page, health, resistances, summon items and drops, comes from the game files of the current build, Valheim 1.0.17, so you can plan the fight around what the boss actually takes damage from.

"Weak to" means the boss takes extra damage from that type; "shrugs off" lists the types it reduces or ignores. Chop and pickaxe damage never hurt a boss. Health is the base value, as the game spawns every boss.
Each boss, and what to bring
1. Eikthyr (Meadows)
Two Deer Trophies on the Mystical Altar summon him. With 500 health and no weakness or resistance at all, any weapon works: a stack of arrows from the Crude Bow, a Flint Spear or a club all do full damage. He drops his trophy and three Hard Antlers, which make the Antler Pickaxe, your first tool for copper and tin.
2. The Elder (Black Forest)
Three Ancient Seeds, from Greydwarf nests, go into the Ancient Bowl. The Elder is weak to fire and immune to poison and spirit, so fire arrows from a Finewood Bow are the classic answer. He drops his trophy and the Swamp Key, which opens the Sunken Crypts and starts the iron age.
3. Bonemass (Swamp)
Ten Withered Bones, found in the Sunken Crypts, go into Boiling Death. Bonemass is weak to blunt and frost, resists slash, is very resistant to pierce and fire, and immune to poison: leave the bow and the sword behind and bring an iron mace, or Frostner, which is blunt and frost at once. Drink a Poison Resistance Mead for his attacks. He drops his trophy and the Wishbone, which leads you to silver and buried treasure.
4. Moder (Mountains)
Moder is summoned with three Dragon Eggs placed in the egg cups at her Sacrificial Altar, and eggs cannot go through a portal, so carry them. She is weak to fire and immune to frost and spirit: Frostner's frost does nothing to her, while fire arrows do extra. Fight her from the ground with a bow while she flies and close in when she lands. She drops her trophy and ten Dragon Tears; two of them build the Artisan Table.
5. Yagluth (Plains)
Five Fuling Totems, taken from Fuling villages, go on the five stands around the Mystical Altar. Yagluth has 10,000 health and no weakness. He is very resistant to pierce and resistant to fire, so arrows and fire arrows are the wrong tools: bring slash or blunt, a Black Metal sword or the Porcupine. He drops his trophy and three Torn Spirits, one of which builds the Wisp Fountain for the Mistlands.
6. The Queen (Mistlands)
There is no altar: the Queen waits inside the Infested Citadel, and the door opens with a Sealbreaker, made at the Galdr Table from nine Sealbreaker Fragments. She resists pierce and is immune to spirit; slash, blunt and the elemental staffs all work. She drops her trophy and five Majestic Carapaces, which build the Artisan Press.
7. Fader (Ashlands)
Three Bells, each made at the Black Forge from three Bell Fragments, go into the bell holders at the Altar of The Emerald Flame. Fader has 25,000 health, resists pierce and is immune to fire and spirit, so spirit weapons and fire do nothing to him: bring slash, blunt, frost or lightning. Fire Resistance Barley Wine halves the fire he breathes. He drops his trophy and five Kindled Ribs, which build the Eternal Pyre that makes Embers for the Deep North's Ember Charges.
8. Kall Fimbulbringer (Deep North)
The final boss sits in The Prison. Its two Strange Bowls take three Malicious Blood each: one opens the gate and the other summons him. Each Malicious Blood comes from breaking a Malicious Ice core, a 1,000-health block that keeps spawning Krigen and Hexen while it stands, so you need six cores. Kall fights in three phases. The first has 10,000 health; the second, 7,000, is immune to every damage type and calls up an aspect of each earlier boss; the third has 30,000. In his damaging phases he resists pierce, fire, frost and lightning and is immune to spirit, which leaves slash and blunt as the full-damage choices. He drops Sacrificial Blood and the Crown Jewel, which makes the Crown of Valheim. He has no trophy and no Forsaken Power.

Before any boss fight
- Sleep in a bed near the altar first. A bed sets your spawn point, so a death puts you back near the fight instead of at the world's start.
- Bring the three best foods you have. Food sets your health and stamina, and it matters more than one weapon tier.
- Read the boss's resistances above before you pick a weapon. Bringing fire arrows to Yagluth or a spirit weapon to Fader wastes the fight.
- More players make the boss tougher. For every extra player within 100 metres, up to five in all, the game cuts the damage the boss takes as if it had 30% more health and lets it hit 4% harder. Five players face a boss with effectively 2.2 times the health, so a group still wins faster, just not five times faster.
Fight them with your group on a Supercraft Valheim server, with daily backups so a lost fight never costs you the world.
