Damage Formula

General Formula for Damage

$$\text{DMG} = (\Sigma(\text{Base DMG} \times \text{BaseDMGMultiplier}) + \text{AdditiveBaseDMGBonus}) \\ \times (1 + \text{DMGBonus} - \text{DMGReduction} {\text{Target}}) \times \text{CRIT} \\ \times \text{ EnemyDefMult} \times \text{EnemyResMult} \times \text{AmplifyingReaction} \\$$

See the sections below for the breakdown of each individual part of the formula.

Base Damage

$$\text{Base DMG} = \begin{cases} \text{Talent\%} \times \text{ATK} & \text{if, Talent scales with ATK} \\ \text{Talent\%} \times \text{DEF} & \text{if, Talent scales with DEF} \\ \text{Talent\%} \times \text{Max HP} & \text{if, Talent scales with Max HP} \\ \text{Talent\%} \times \text{EM} & \text{if, Talent scales with EM} \end{cases}$$ $$\text{ATK} = (\text{AttackCharacter} + \text{AttackWeapon}) \times (1 + \text{AttackBonus}) + \text{FlatAttack}$$ $$\text{DEF} = \text{DefenseCharacter} \times (1 + \text{DefenseBonus}) + \text{FlatDefense}$$ $$\text{Max HP} = \text{HealthCharacter} \times (1 + \text{HealthBonus}) + \text{FlatHealth}$$

$$\text{EnemyResMult} = \begin{cases} 1 - \frac{\text{Resistance}}{2} & \text{if, } \text{Resistance} \lt 0 \\ 1 - \text{Resistance} & \text{if, } 0 \le \text{Resistance} \lt 0.75 \\ \frac{1}{4 \times \text{Resistance} + 1} & \text{if, } \text{Resistance} \ge 0.75 \end{cases}$$ $$\text{Resistance} = \text{BaseResistance} - \text{ResistanceReduction}$$

Formula Variable	Explanation

ResistanceReduction	The total resistance reduction of the relevant Element from effects such as Superconduct and Viridescent Venerer.

Base DMG Multiplier

Unlike other bonuses, these are directly multiplicative with base Talent scaling. They can be considered a multiplier of the Talent motion value.

$$\text{BaseDMGMultiplier} = \begin{cases} 2 & \text{if, World-Shaker triggered} \\ 1.5 & \text{if, Evilsoother triggered} \\ \text{Talent \%} & \text{if, Niwabi Fire-Dance or Hanega: Song of the Wind triggered} \\ 1 & \text{otherwise} \end{cases}$$

Evilsoother	Xingqiu’s Constellation 4 ability applies a 1.5 buff to his Elemental Skill.
Niwabi Fire-Dance	Yoimiya's Elemental Skill applies a scaling buff to her Normal Attacks.

$$\text{AmplifyingReaction} = \text{ReactionMultiplier} \times \biggl(1 + \frac{2.78 \times \text{EM}}{1400 + \text{EM}} + \text{ReactionBonus}\biggr)$$ $$\text{ReactionMultiplier} = \begin{cases} 2 & \text{if, triggering Vaporize with {\color{4688ff}Hydro} or Melt with {\color{f68f9a}Pyro}}\\ 1.5 & \text{if, triggering Vaporize with {\color{f68f9a}Pyro} or Melt with {\color{7ba4d3}Cryo}}\end{cases}$$

EM	The character's total Elemental Mastery.
ReactionBonus	Includes reaction damage bonuses from the 4-Piece set bonuses of Thundering Fury and Viridescent Venerer, Mona's C1, and Nilou's A4.

EnemyResistanceMultiplier	Uses the Enemy Resistance formula above, but for the Element of the Transformative Reaction (Pyro for Overloaded, Physical for Shattered, Electro for Electro-Charged, Cryo for Superconduct, the Element being Swirled for Swirl, and Dendro for Bloom, Bugeon, and Hyperbloom).

Additive Reaction

$$\text{AdditiveReaction} = \text{ReactionMultiplier} \times \text{LevelMultiplier} \times \biggl(1 + \frac{5 \times \text{EM}}{1200 + \text{EM}} + \text{ReactionBonus}\biggr)$$ $$\text{ReactionMultiplier} = \begin{cases} 1.25 \ \text{if, triggering {\color{00eb50}Spread}}\\ 1.15 \ \text{if, triggering {\color{df96fe}Aggravate}} \end{cases}$$

ReactionBonus	Includes reaction damage bonus from 4-Piece set bonus of Thundering Fury.
LevelMultiplier	Player level multiplier at Lv. : 1446.85 Enemy/environment level multiplier at Lv. : 1202.81

Proc

The damage dealt by weapon and ability procs when they trigger, such as Prototype Archaic or Xiangling's constellation 2. This is dealt as a separate instance of damage from the attack that triggered it.

To calculate this damage, substitute the proc percentage (e.g. 240% for Prototype Archaic R1) for Talent in the damage formula. Note that weapon proc effects always deal Physical damage, and are therefore affected by Physical damage bonuses and Physical resistance, even if an Elemental attack is used to trigger them.

Additional Notes

Any effect that scales off of a certain stat will not count any buffs that also scale themselves off of someone else's stat in their calculation.

"In order to avoid infinite stacking of in-game bonuses, when an effect confers one attribute as a certain percentage of another attribute, this effect will not then factor into calculations of other similar percentage-based effects." - HoYoverse

Examples of such buffs:

• Sucrose's Mollis Favonius (A4): EM share
• Kaedehara Kazuha's Poetics of Fuubutsu (A4): DMG% buff
• Electro Traveler's Resounding Roar (A4): Energy Recharge buff
