Damage & Combat Calculator

Compare builds by expected damage per hit, including crits and mitigation.

Estimate normal, critical, and expected damage per hit from attack, crit rate, crit multiplier, and a flat damage reduction.

Inputs

Pre-mitigation attack stat.
Flat % reduction from defense/armor.

Result

Expected 77.0 dmg/hit
Normal hit70.0
Critical hit105.0
Expected per hit77.0

Expected damage blends the normal and crit outcomes by your crit rate after the flat reduction. This is a generic model — real games add penetration, buffs, and conditional multipliers not included here.

Generic formula for comparing builds; game-specific mechanics (penetration, buffs, conditional damage) are not modeled.
Why expected damage beats eyeballing crits

Scenario: you are choosing between +10% attack and +15% crit damage. Which raises your real output more? The calculator blends both outcomes by your crit rate so you can compare apples to apples.

Example: 100 base attack, 20% crit at 150% crit multiplier, 30% reduction → normal hit 70, crit 105, expected ≈ 76 per hit. Bump crit multiplier to 200% and expected rises to 84.

Boundaries: this is a generic model. It ignores penetration, conditional multipliers, buffs, and enemy-specific resistances that real games apply on top.

FAQ: is higher crit rate always better than higher attack? Not always — at low crit multiplier, raw attack scales both outcomes, while crit rate only helps the crit portion. Compare both through expected damage, not a single stat.
