Valheim Damage Calculator | Weapon Effectiveness & TTK Tool

The Ultimate Valheim Damage Guide

Welcome to the most advanced Valheim Damage Calculator. Valheim’s combat system relies on hidden math involving skill scaling modifiers, randomized damage ranges, stagger bonuses, and intricate enemy resistances. This tool removes the guesswork, allowing you to optimize your weapon choices before heading into the Ashlands or Mistlands.

How Valheim Damage is Calculated

When you strike an enemy, your final damage isn't just the number on the tooltip. The calculation goes through several layers:

• Base Range & Skill Scaling: The yellow number in brackets on your weapon is your current guaranteed damage range based on your skill level. At Level 0 skill, your damage rolls between 25% to 55% of the weapon's base damage. At Level 100, it rolls between 85% to 100%.
• Enemy Resistances: Every creature in Valheim has a resistance profile. 'Weak' enemies take 1.5x damage from a specific type. 'Very Weak' take 2x. 'Resistant' enemies take 0.5x, 'Very Resistant' take 0.25x, and 'Immune' take 0 damage.
• Combat Modifiers: Hitting a staggered enemy applies a 2x multiplier to all incoming damage. A successful sneak attack applies the weapon's backstab multiplier (usually 3x or 6x).

How to Use This Calculator

This SaaS-grade tool simulates the exact in-game combat engine. Follow these steps to determine your Time-to-Kill (TTK):

1. Input your Skill: Use the slider to set your current skill level for the weapon you are testing (e.g., Swords, Bows).
2. Set Base Damage: Look at your weapon's raw stats (the white numbers, not the yellow ones in brackets) and input them into the grid. Include physical and elemental splits (like the Silver Sword's Slash + Spirit).
3. Select your Target: Choose an enemy from the dropdown list. The tool automatically pulls their maximum HP and hidden resistance multipliers.
4. Toggle Modifiers: Check the boxes if you plan to sneak attack or if you consistently stagger enemies (like with a parry).
5. Review the Dashboard: Watch the Hits-to-Kill and the Damage Penetration meter. The Weapon Effectiveness Grade (S to F) will tell you instantly if you are using the right tool for the job.

Tips & Best Practices for Combat Strategy

To dominate Valheim, you must match your weapon to the biome:

• The Swamp Rule (Blunt Damage): Maces are king in the Swamp. Blobs, Oozers, and Bonemass are heavily resistant to Pierce and Slash, but Weak to Blunt. Our calculator will show your "Efficiency Meter" drop to 50% if you use a Sword, but stay at 150% with a Mace.
• Spirit Damage Limitations: Spirit damage is incredibly potent against undead (Skeletons, Draugr, Growths), but completely useless against living creatures like Trolls or Fulings. The Damage Distribution Chart will visually show your Spirit damage disappearing if you select an immune target.
• Parry to Win: The Stagger modifier (2x damage) is the most powerful mechanic in the game. A parry followed by a secondary attack (which usually has its own hidden damage multiplier) can one-shot most elite enemies.

Frequently Asked Questions (FAQ)

How is Valheim damage calculated?

Valheim damage is a range determined by your weapon's base stats and your skill level. At skill level 0, you deal 25% to 55% of the weapon's base damage. At level 100, you deal 85% to 100% of the base damage.

How do enemy resistances work in Valheim?

Resistances multiply incoming damage of specific types. 'Weak' multiplies damage by 1.5x, 'Very Weak' by 2x, 'Resistant' cuts damage in half (0.5x), 'Very Resistant' cuts it to 0.25x, and 'Immune' reduces it to 0.

Does the stagger modifier double all damage?

Yes, when an enemy's stagger bar is filled (often by parrying), they take 2x damage from all incoming sources for the duration of the stagger animation. This applies to both physical and elemental damage types.
