Damage Formula

Explanation on how damage is calculated in Tower of Fantasy (WIP).

Datamined Damage Formula

This is the formula found in the game files by Afrodiy#9769 and Sova#0618, but it isn't fully understood.

"GMExecutionInfo": "Skill ID: {0}, Current Stat Conversion: {1}, Target's Current HP: {2}, Target's HP Left: {16}, Attacker: {18}, Target: {19}

Formula: Max (Base ATK {7} × Skill Ratio {3} + Fixed Skill Value {4}) ×0.1, Base ATK {7} × revised Skill Ratio {5} + revised Fixed Skill Value {6}), Max Sum ({8}) × Crit Damage Ratio {11} × True DEF Conversion {9} × Module Ratio {10} × (1 + Damage Fluctuation {12}) × Headshot Ratio {14} × Final Module Ratio {15} = {17}",

Adapted Damage Formula

This still stays questionable as this is a topic yet to be properly understood.

​​Damage=BaseDamage×Crit×EnemyDefMult×DamageBonusDamage=BaseDamage×Crit×EnemyDefMult× DamageBonus×(1+DamageFluctuation)×HeadshotMult×(1+DamageFluctuation)×HeadshotMult

Base Damage

BaseDamage=ATK×SkillPercent+FlatSkillBaseDamage = ATK × SkillPercent + FlatSkill

ATK=FlatATK×(1+ATKBonus)ATK = FlatATK × (1 + ATKBonus)

Formula VariableExplanation

SkillPercent

The scaling percentage-based number of a specific attack.

FlatSkill

The scaling non-percentage-based number of a specific attack.

FlatATK

Sum of all non-percentage-based attack from character, suppressor, weapons, equipment, matrices.

ATKBonus

Sum off all percentage-based attack from buffs and other sources.

DamageBonus

All percentage-based damage buffs multiplied to each other.

Critical Hits

Crit={1+CritDamage1Crit =\begin{cases}1 + CritDamage\\1\end{cases} first option if Critical Hit, second otherwise

AverageCrit=1+TotalCritRate×CritDamageAverageCrit = 1 + TotalCritRate × CritDamage

​Crit Rate

TotalCritRate=FlatCritCritLevelMultiplier+CritRateTotalCritRate = \frac{FlatCrit}{CritLevelMultiplier} + CritRate

CritLevelMultiplier=a×Level2+b×Level+cCritLevelMultiplier = a×Level^{2}+b×Level+c

Formula VariableExplanation

TotalCritRate

The total Crit Rate from all possible sources.

FlatCrit

Sum of non-percentage-based Crit from suppressor, weapons, equipment, matrices.

CritRate

Percentage-based Crit Rate already present before Flat Crit conversion.

Enemy Defense Multiplier

Complete formula is currently unknown.

Damage Fluctuation

Random multiplier which ranges between -0.05 and 0.05. This changes the damage slightly resulting in seeing minor differences in damage numbers despite having the same stats.

Headshot Multiplier

Currently unknown.
