Genshin Impact Damage Formula Explained

The Genshin Impact damage formula uses a multiplicative stacking system where each component amplifies the final output. Understanding how ATK, CRIT, DMG Bonus, DEF, RES, and reactions interact is essential for optimizing your character builds.

Total DMG = ATK × (Skill Multiplier% ÷ 100) × (1 + DMG Bonus%) × CRIT Factor × DEF Multiplier × RES Multiplier × Reaction Multiplier

Reaction MultiplierDepends on reaction type1.0 – 2.0

RES Multiplier Rules

If RES < 0: multiplier = 1 − RES/2. If 0 ≤ RES < 0.75: multiplier = 1 − RES. If RES ≥ 0.75: multiplier = 1/(1 + 4×RES).

How Genshin Impact Damage Calculation Works

Genshin Impact damage follows a structured multiplicative formula. Each component stacks independently, meaning balanced investment across ATK, CRIT, and DMG Bonus yields the highest total output. Follow this framework to understand your damage:

  1. Start with Base DMG — Multiply your total ATK by the skill's talent multiplier percentage to get the raw base damage value.
  2. Apply DMG Bonus — Add all sources of DMG bonus (Elemental Goblet, set bonuses, weapon passives) as a single multiplier: 1 + total DMG Bonus%.
  3. Factor CRIT — For average damage, use 1 + CRIT Rate% × CRIT DMG%. For max crit hit damage, use 1 + CRIT DMG%.
  4. Apply DEF reduction — The DEF multiplier depends on your character level vs. enemy level. Same-level enemies halve your damage.
  5. Apply RES reduction — Enemy elemental resistance further reduces or (when negative) amplifies damage based on the RES formula.
  6. Apply reaction multiplier — Vaporize, Melt, and additive reactions like Aggravate apply final multipliers or flat bonuses.

Elemental Reaction Mechanics in Genshin Impact

Elemental reactions are a core combat mechanic that can dramatically increase damage output. Amplifying reactions like Vaporize and Melt multiply total damage, while additive reactions like Aggravate and Spread add flat bonus damage that scales with Elemental Mastery and character level.

Amplifying Reaction Multipliers

ReactionForward TriggerReverse Trigger
VaporizeHydro → Pyro: 2.0×Pyro → Hydro: 1.5×
MeltPyro → Cryo: 2.0×Cryo → Pyro: 1.5×

Additive Reaction Scaling

Aggravate and Spread add flat damage calculated as: Bonus DMG = Base_Reaction_DMG × (1 + EM_Bonus% + Reaction_Bonus%) × CRIT Factor × DEF × RES. The base reaction damage scales with character level, making level 90 significantly stronger than level 80 for these reactions.

People Also Ask About Genshin Damage Calculation

Genshin Impact damage follows a multiplicative formula: Total DMG = ATK × Skill Multiplier% × (1 + DMG Bonus%) × CRIT Factor × DEF Multiplier × RES Multiplier × Reaction Multiplier. Each factor stacks multiplicatively, meaning optimizing multiple stats yields exponentially better results than stacking a single stat like ATK alone.
The DEF multiplier reduces damage based on the level difference between your character and the enemy. The formula is: (Character Level + 100) / ((Enemy Level + 100) + (Character Level + 100)). Against same-level enemies this is exactly 0.5, meaning half of your damage passes through. Higher-level enemies reduce damage further.
Elemental reactions provide damage multipliers: Vaporize and Melt multiply total damage (1.5× or 2× depending on trigger order), while Aggravate and Spread add flat bonus damage that scales with Elemental Mastery and character level. The calculator supports all major reaction types with their standard multipliers for accurate total DMG estimation.
A widely recommended CRIT ratio is 1:2 (CRIT Rate to CRIT DMG). For example, 70% CRIT Rate with 140% CRIT DMG provides mathematically optimal average damage output. The calculator displays both average damage (accounting for CRIT Rate) and maximum critical hit damage so you can evaluate both scenarios side by side.
Yes, character level directly affects the DEF multiplier when fighting enemies of different levels. A level 90 character deals more damage to a level 90 enemy than a level 80 character would. Level also affects reaction bonus damage for additive reactions like Aggravate and Spread, making level 90 significantly more impactful for reaction-focused teams.

Frequently Asked Genshin Damage Calculator Questions

Yes. The calculator includes ATK, skill multiplier, CRIT Rate, CRIT DMG, elemental DMG bonus, DEF multiplier (based on character and enemy levels), RES multiplier, and reaction multiplier. It covers all major components of the official Genshin Impact damage formula for accurate estimates.
Absolutely. The calculator displays both average damage (which factors your CRIT Rate into the expected output) and maximum critical hit damage (which assumes every hit crits). This dual display helps you understand your damage floor and ceiling for better build planning.
Enter the enemy's base RES percentage in the Enemy RES field. If you have RES shred from artifacts (like Viridescent Venerer), subtract that value from the enemy's base RES before entering. For example, a 10% RES enemy with 40% VV shred becomes -30% RES, which you would enter as -30.
Vaporize uses 1.5× when Pyro triggers on Hydro (reverse Vaporize, most common for Hu Tao, Xiangling) and 2.0× when Hydro triggers on Pyro (forward Vaporize, used by Childe, Mona nuke setups). Select the appropriate multiplier based on your team's trigger order.
Yes. The calculator supports Aggravate and Spread, which are additive reactions that add flat bonus damage scaling with Elemental Mastery and character level. When you select Aggravate or Spread, the EM field appears so you can enter your Elemental Mastery for accurate bonus damage calculation.
Yes. By adjusting the ATK, CRIT stats, and DMG Bonus values, you can simulate different artifact configurations. Run the calculator with one set of values, note the result, then change the inputs to match a different build and compare the outputs to find your optimal setup.

Genshin Impact Damage Glossary

Base DMG

The raw damage value calculated by multiplying total ATK by the skill's talent multiplier percentage, before any bonuses are applied.

CRIT Factor

The multiplier representing critical hit contribution. Average CRIT factor = 1 + CRIT Rate × CRIT DMG. Max crit factor = 1 + CRIT DMG.

DMG Bonus

The sum of all percentage damage bonuses including Elemental DMG Bonus, Normal/Charged/Burst DMG Bonus, and set effects, applied as 1 + total bonus%.

DEF Multiplier

A reduction factor based on the level ratio between character and enemy. Same-level: 0.5. Higher enemy level reduces damage further.

RES Multiplier

Enemy elemental resistance adjustment. RES below 0 amplifies damage (1 − RES/2), RES between 0–75% reduces linearly, RES above 75% uses diminishing formula.

Amplifying Reaction

Vaporize and Melt reactions that multiply total damage by a fixed multiplier (1.5× or 2.0×) depending on the elemental trigger order.

Additive Reaction

Aggravate and Spread reactions that add flat bonus damage calculated from base reaction damage, Elemental Mastery scaling, and character level.

Elemental Mastery

A stat that amplifies reaction damage. For Vaporize/Melt it provides a percentage bonus to the reaction multiplier. For Aggravate/Spread it directly increases flat bonus damage.
