Damage Types

Damage types are a core combat mechanic in Valheim. Enemies and bosses can be resistant, immune, or weak to specific damage types, and matching your weapon to a target’s weakness can massively increase kill speed and survivability. This page covers the main damage types, common sources, and a quick boss weakness reference by biome.

🧾 How resistances work

Damage types are modified by the target’s resistances.
**Weak** targets take increased damage.
**Resistant** targets take reduced damage.
**Immune** targets take no damage of that type.
Many enemies have multiple modifiers (for example, resistant to Pierce but weak to Blunt).
Elemental and Spirit damage are especially important for certain biomes and undead enemies.

⚔️ Physical Damage Types

Type	What it’s good for	Common sources
Slash	General-purpose damage; effective vs many living enemies	Swords, Axes, Knives
Pierce	Strong on ranged weapons and spears; good vs many creatures but not all	Bows, Spears, Atgeirs, Crossbows
Blunt	Excellent vs undead and many swamp enemies	Clubs, Maces, Sledgehammers

✨ Elemental & Special Damage Types

Type	What it does	Common sources
Fire	Damage over time effect; strong pressure tool and crowd control	Fire arrows, Staff of Embers, some late-game weapons
Frost	Slows targets and reduces movement speed; strong control tool	Frost arrows, Staff of Frost, some biome weapons
Poison	Damage over time; great vs high-health targets that aren’t resistant	Poison arrows, certain weapons and effects
Lightning	High burst elemental damage (late-game)	Ashlands-tier weapons and effects
Spirit	Bonus damage vs undead and certain supernatural enemies	Silver weapons, some special items

🛡 Quick tips for weapon choice

Carry at least **two** melee options if possible:

 * One general-purpose (often Slash or Pierce)
 * One for counters (often Blunt or Spirit)

In the Swamp, having a strong **Blunt** weapon is a huge difficulty reducer.
In late biomes, elemental effects (Fire, Frost, Lightning) become more valuable for control and burst.

👑 Boss Weakness Quick Reference

This table is designed for fast lookup while progressing biome to biome.

Boss	Biome	Generally strong against	Generally weak to	Notes
Eikthyr	Meadows	Pierce (often resisted)	Fire	Early boss; fire arrows help new players a lot
The Elder	Black Forest	Pierce (often resisted)	Fire	Fire damage is a consistent advantage for this fight
Bonemass	Swamp	Slash, Pierce, Poison	Blunt	Blunt weapons are the most reliable counter; bring a mace
Moder	Mountains	—	Pierce	Ranged Pierce pressure is strong; stay mobile
Yagluth	Plains	Fire	Frost	Frost damage tends to outperform fire-based approaches here
The Queen	Mistlands	—	Fire	Fire-based magic and sustained DPS approaches perform well
Fader	Ashlands	Fire	Frost	Fire-heavy builds lose value; frost control is helpful
