Valheim Enemy Weaknesses & Resistances by Damage Type

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.

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.

Deep North (1.0)

Enemy	Weak to	Resistant	Immune

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.
