How to use this page

Scroll to the biome you are currently in, find the enemy you are fighting, and check the Weak to column. That is the damage type you should prioritize — everything else is either reduced or zero damage. The table is grouped by biome so you can look up your whole run at once.

Verified (1.0): the “weak / resistant / immune” labels below are directional and confirmed against valheim.wiki (1.0), cross-checked with gamecore.wiki and allthings.how. The exact per-tier multipliers (2.0x down to 0.0x) are published on the damage types guide. See our verification workflow.

Damage type key

Damage type Source
Blunt Clubs, maces, sledges
Slash Swords, axes, atgeirs
Pierce Spears, bows, crossbows
Fire Fire arrows, Staff of Embers, some gem-socket weapons
Frost Frost arrows, Staff of Frost, Frostner
Poison Poison arrows, Draugr Fang, Staff of the Wild
Spirit Silver weapons, spirit arrows
Lightning Gem-socket lightning weapons, Dundr

Bosses

Boss Weak to Resistant Immune
Eikthyr — (no real weakness) — Stagger (unique — not a damage type)
The Elder Fire — Poison, Spirit, Stagger
Bonemass Blunt, Frost Fire, Pierce, Slash Poison, Stagger
Moder Fire — Frost, Spirit, Stagger
Yagluth — (no real weakness) Fire, Pierce (very) Poison, Stagger
The Queen — (no real weakness) Pierce Spirit
Fader — (no real weakness) Pierce Fire, Spirit, Stagger
Kall Fimbulbringer — (no real weakness) Pierce, Fire, Frost, Lightning Spirit

Note: A “no real weakness” boss takes full (×1) damage from every physical type (blunt, slash, pierce, frost), so “weak to —” means no damage type out-damages the others — just bring a strong blunt or slash weapon and the right resistance. Kall Fimbulbringer (Deep North) is the 1.0 final boss; unlike the other Forsaken he has no trophy and no Forsaken Power.

Enemy Weak to Resistant Immune
Seal Fire — —
Moose Fire — —
Elaking Fire — —
Barka Fire All other damage types —
Eyeless One Blunt, Slash — —
Gammeltroll Head (very weak) Most physical damage types —

Note: The Deep North is the final 1.0 biome. Moose can be tamed with Lingonberries and ridden with a Moose Saddle. Gammeltrolls are resistant to most physical damage types, but their head is a very weak point — aim strikes there or throw Ember Charges (crafted from Embers at an Eternal Pyre) to deal meaningful damage. When defeated, a Gammeltroll petrifies into a statue that is blown up with Ember Charges to harvest Petrified Tissue. The biome’s boss, Kall Fimbulbringer, is listed in the Bosses table above: resistant to pierce, fire, frost and lightning, immune to spirit, so blunt and slash are your reliable damage.

What this means for your weapon

  • Heading into the Swamp? Iron Mace (blunt) for Blobs, Oozers and Bonemass — one weapon solves most of the biome.
  • About to enter a cave full of skeletons? Bronze Mace or Iron Mace — blunt is the universal skeleton answer.
  • Fighting Moder? Fire arrows or a fire weapon — leave frost arrows at camp.
  • Going into the Ashlands? Frost or Lightning weapons make Charred enemies easy; fire does nothing.

Frequently asked questions

Why do damage-type mismatches feel so punishing?
Because resistances halve (or quarter) your damage and immunities reduce it to zero. A frost weapon against Moder lands nothing — she is immune to frost. A weapon with the right damage type, or a strong blunt/slash weapon against a boss with no real weakness, ends fights in half the time with no extra stamina cost.
Is the Damage multiplier always 2x for weak targets?
No. The six resistance tiers run from 2.0x (Very Weak) down to 0.0x (Immune) — published on the [damage types guide](/gear/damage-types-guide/). This page lists *directional* weaknesses and immunities (weak to X, resistant to Y, immune to Z) so you can pick the right weapon; the per-boss multipliers are on that page. See our [verification workflow](/about/).
Can a single enemy have both a weakness and an immunity?
Yes, very commonly. Bonemass is weak to blunt and frost, resistant to fire/pierce/slash, and immune to poison and stagger. Yagluth has no real weakness but is very resistant to pierce, resistant to fire, and immune to poison. Matching the right damage type matters even when there is one weakness and one immunity.
What weapon should I use against Moder?
Fire. Moder is immune to frost and spirit, so leave frost arrows at camp and bring fire arrows or a fire weapon. She has no other real weakness, so a strong fire option ends the fight fastest.
What is Bonemass weak to?
Bonemass is weak to blunt and frost, resistant to fire, pierce and slash, and immune to poison and stagger. An Iron Mace (blunt) solves most of the Swamp, including Bonemass himself.
What are Deathsquitos weak to?
Deathsquitos are weak to pierce and resistant to blunt, immune to poison — and they hit for about 90 pierce damage each. Carry a shield and a piercing weapon, and kill them before they swarm you in the Plains.
