Example Data Table

Weapon	Infusion	Upgrade	Stats	Motion	Enemy Setup	Use Case
Longsword	Refined	+10	40 STR, 40 DEX	100%	120 defense, 15% absorption	Quality build check
Lothric Knight Sword	Sharp	+10	18 STR, 60 DEX	110%	130 defense, 18% absorption	Dexterity duel test

Formula Used

This calculator uses an estimate model for build comparison. It is designed for planning, not exact internal game replication.

Effective Strength:

Effective Strength = Strength × 1.5 when two handed. The value is capped at 99.

Upgrade Multiplier:

Upgrade Multiplier = 1 + Upgrade Level × 0.09

Scaling Bonus:

Scaling Total = Grade Value × Stat Factor × Infusion Modifier

Attack Rating:

Attack Rating = Base AR × Upgrade Multiplier × Infusion Base Modifier × Scaling Multiplier

Pre Defense Damage:

Pre Defense = Attack Rating × Motion Value × Buff Multiplier × Counter Multiplier

Final Split Damage:

Final Split = Pre Defense × 100 / (100 + Defense × 0.72) × (1 - Absorption)

Statistical Range:

Low = Combo Damage × (1 - Variance Band)

High = Combo Damage × (1 + Variance Band)

About This DS3 Weapon Damage Calculator

This calculator helps compare Dark Souls 3 weapon plans before a respec or upgrade. It combines attack rating, scaling, upgrade level, buffs, motion value, enemy defense, and absorption. The result is not a hidden game engine clone. It is a clear planning model for build testing.

Why Damage Varies

Weapon damage changes because many parts interact. Base attack gives the starting number. Scaling adds value from Strength, Dexterity, Intelligence, Faith, or Luck. Infusion changes both base attack and scaling strength. Upgrade level multiplies the weapon's listed power. Buffs add flat damage or percentage gains. A two handed stance can raise effective Strength. Motion value explains why a light hit and charged hit deal different damage.

Statistical Use

The tool also adds a small statistical view. It estimates low, average, and high damage by applying a variance band. This helps when you want a safe expectation instead of one exact number. Damage per stamina shows efficiency. Damage per second helps compare fast and slow weapons. Total combo damage helps plan punish windows.

Best Use Cases

Use this calculator when comparing two weapons with the same build. It is also useful when testing infusions, rings, spell buffs, or enemy defenses. You can save the results as CSV or PDF. That makes it easy to keep build notes or share findings with other players.

Interpreting Results

Treat the output as a practical estimate. Real in game damage can differ because of hidden modifiers, split defense behavior, counter frames, critical hits, armor rules, and patch details. Still, the method gives a consistent baseline. It shows how one change affects the final result. Enter honest weapon values. Compare builds using the same enemy settings. That keeps every result fair and useful.

Input Tips

Use listed weapon attack after upgrades when possible. Add only active buffs. Put enemy absorption as a percentage. Choose one handed or two handed before comparing.

Limits

The calculator is best for planning, not frame perfect testing. It does not read save files or game memory. It cannot know every special weapon effect. Use repeated entries to compare choices, then test your favorite setup in game. Small changes often reveal the strongest practical build choice quickly.

FAQs

Is this calculator exact to the game engine?

No. It is an estimate tool for build planning. Dark Souls 3 has hidden rules, split defense behavior, and special modifiers. Use it for fair comparisons between setups.

What is motion value?

Motion value is the attack modifier for a move. A quick light attack may use a lower value. A charged heavy attack usually uses a higher value.

Does two handing change the result?

Yes. Two handing increases effective Strength in this calculator. That can improve scaling damage for weapons that benefit from Strength.

Can I test split damage weapons?

Yes. Enter physical, magic, fire, lightning, and dark attack values. Each damage type is reduced by its matching enemy defense and absorption.

What should I enter for buffs?

Use flat buff for added attack rating. Use percent buff for general multipliers. Select the damage type that receives the flat bonus.

Why include variance?

Variance gives a practical low and high estimate. It helps compare builds without trusting one exact number too much.

Can I export my results?

Yes. Use Download CSV for spreadsheet notes. Use Download PDF to save a readable report of the current result.

Why is this listed under Statistics?

The calculator includes ranges, variance, standard deviation, damage efficiency, and damage per second. These outputs help compare weapons statistically.
