How the Genshin damage calculator works
This Genshin damage calculator follows the major layers used by a single outgoing hit: the character's final scaling stat, talent percentage, applicable damage bonuses, critical stats, enemy defense, enemy resistance, and any selected elemental reaction. Enter values from the in-game details and talent screens, then compare the non-critical hit, guaranteed critical hit, and probability-weighted average. The result is an estimate, because some character kits add special multipliers or damage instances that a generic formula cannot identify automatically.
The calculator keeps direct, additive, amplifying, and transformative reactions separate. That distinction matters: Vaporize multiplies a triggering hit, Aggravate adds damage before normal hit multipliers, and Hyperbloom creates an independent reaction hit based mainly on character level and Elemental Mastery.
Genshin direct damage formula explained
A normal talent begins with a scaling value such as ATK, Max HP, or DEF multiplied by the talent percentage. Flat base damage is added at the same stage. The applicable DMG Bonus then multiplies that base, followed by critical damage when the hit crits and the enemy's defense and resistance multipliers. Bonuses that do not apply to the selected attack should not be included.
| Layer | Formula | What it changes |
|---|---|---|
| Talent base | Scaling stat × Talent % + Flat damage | The raw hit before multipliers |
| Average crit | 1 + Crit Rate × Crit DMG | Probability-weighted average over many hits |
| Defense | Attacker term ÷ (attacker + enemy terms) | Level-based enemy mitigation |
| Resistance | Piecewise multiplier from final resistance | Element-specific or Physical mitigation |
| Amplifying EM | 2.78 × EM ÷ (EM + 1400) | Vaporize and Melt multiplier bonus |
| Transformative EM | 16 × EM ÷ (EM + 2000) | Independent reaction damage bonus |

The upper path represents a direct talent hit. Aggravate and Spread enter near the base; Vaporize and Melt multiply the triggering hit. The lower path is independent, so transformative reactions ignore talent scaling, ordinary DMG Bonus, critical stats, and enemy defense.
Crit Rate, Crit Damage, and average damage
A critical-hit result assumes the hit crits and multiplies the non-crit result by one plus Crit Damage. Expected average damage instead weights the two outcomes by Crit Rate. At 70% Crit Rate and 140% Crit Damage, the average crit factor is 1.98. Crit Rate above 100% cannot increase ordinary hit probability further, so the tool caps only the expected-value calculation and displays a warning.
The familiar 1:2 Crit Rate to Crit Damage ratio is a useful allocation guideline, not a universal target. Buff uptime, guaranteed crit mechanics, reaction ownership, and the amount of ATK or Elemental Mastery sacrificed can change the best build.
Enemy defense and resistance multipliers
Enemy defense compares attacker and enemy levels. Against an equal-level enemy with no reduction or ignore, the standard multiplier is 0.5. DEF reduction and DEF ignore are separate multiplicative terms in the enemy portion of the equation, so adding their percentages together produces the wrong answer.
Resistance uses three branches. Normal resistance below 75% subtracts directly from one. Negative resistance is only half as effective beyond zero, while resistance of at least 75% follows a stronger diminishing formula. Enter the final resistance after any shred that applies to the damage element.
Vaporize, Melt, Aggravate, and Spread damage
Hydro triggering Vaporize on Pyro and Pyro triggering Melt on Cryo use a 2.0 base multiplier. The opposite directions use 1.5. Elemental Mastery and reaction-specific bonuses increase that multiplier before the normal damage layers finish the hit.
Aggravate and Spread behave differently. They add a level-scaled amount to the attack's base before applicable DMG Bonus, critical, defense, and resistance multipliers. Aggravate uses a 1.15 coefficient and Spread uses 1.25, with Elemental Mastery following the additive-reaction curve.
Transformative reaction damage and Elemental Mastery
Overloaded, Electro-Charged, Superconduct, Swirl, Shattered, Burning, Bloom, Burgeon, and Hyperbloom create separate reaction damage. Their main inputs are the triggering character's level, reaction coefficient, Elemental Mastery, reaction-specific bonuses, and target resistance.
These reactions ordinarily do not use the trigger's ATK, talent percentage, regular elemental DMG Bonus, Crit Rate, Crit Damage, or enemy defense. The game can introduce named exceptions through character or reaction mechanics, so compare special kit text before treating a generic estimate as exact.
Frequently asked questions
How do I calculate damage in Genshin Impact?
Multiply the final scaling stat by the talent percentage, add eligible flat and additive damage, then apply DMG Bonus, reaction, critical, defense, and resistance factors in their correct layers. This calculator performs those steps without rounding intermediate values.
What is a good Crit Rate to Crit Damage ratio?
A 1:2 ratio is a practical starting point when comparing equal amounts of Crit Rate and Crit Damage. Actual build quality also depends on ATK, HP or DEF scaling, reaction stats, set bonuses, buffs, and whether a character has conditional crit effects.
Does Elemental Mastery increase Vaporize and Melt damage?
Yes. Elemental Mastery increases the reaction multiplier through a diminishing-return curve, and reaction-specific bonuses are added in the same reaction bonus group. The underlying hit still uses its normal talent, damage, crit, defense, and resistance layers.
Can transformative reactions crit in Genshin Impact?
Ordinary transformative reactions do not use the triggering character's Crit Rate or Crit Damage. A named game mechanic may create an exception, but it should not be assumed or applied to every reaction.
How does enemy resistance affect damage?
Resistance reduces damage of the corresponding element or Physical type. Shredding resistance below zero continues to increase damage at half effectiveness, while very high resistance uses a separate diminishing formula.
Why does the calculator differ from my in-game damage?
Common causes are an incorrect final buffed stat, a missing passive, the wrong enemy resistance, a special character multiplier, reaction ownership, or display rounding. Test on the same enemy and confirm every buff is active before comparing values.
