Damage Calculation

==Types==
Each damaging attack has multiple types that determine how the damage is calculated.
===Element type===
Element type is one of
* physical: white damage numbers,
** critical hit: gold damage numbers
* lightning: yellow damage numbers,
* fire: red damage numbers,
* ice: blue damage numbers.
The last three are collectively called elemental damage. Damage calculation is very different for physical and elemental damage:
* Resistance: enemies can have different resistance values for each element type.
* Criticals: physical attacks can crit, elemental attacks cannot.
* Defense: physical attacks are mitigated by enemy defense, elemental attacks are not.
* Shields: physical damage is mitigated by elite/boss passive shields, elemental damage is not.
Notably, Q-Singularis bleed, poison mist and reflected damage from shields are physical damage.
===Attack type===
Attack type is one of
Attack type 	Example skill 	Example modifier
Basic attack 	White Comet's basic skill 	Otto Apocalypse T
Combo attack 	White Comet's special skill Comet Fall 	Jixuanyuan Aqua T
Charge attack 	Swallowtail Phantasm's special skill 	Jixuanyuan M
Dash attack 	Battle Storm's special skillJust3c, Honkai Impact 3 Attack Types Explained, 2018. Available online, 2021.	
Switch skill/QTE	White Comet's special skill Neko Stomp is a switch skill and Aerial Helix is a QTE 	Jixuanyuan T
Weapon skill 	Cross 	Jixuanyuan B
Ultimate 	Ultimate skills 	
No tag 	Lier Scarlet M 	
Notably, certain ultimates (e.g. White Comet's Neko-Charm! and Shadow Knight's Raging Tiger) transform basic attacks into ultimate type during their burst mode. Consequently, effects such as Planck M will not work during the burst mode.Just3c, Honkai Impact 3 Damage/Bonuses Explained, 2018. Available online, 2021.
===Range type===
Attacks are melee, ranged or neither.
For example, Valkyrie Chariot's basic and charged attack are ranged but her QTE is melee. The second hit of White Comet's basic attack string is ranged, other hits are melee. Lier Scarlet M, 5th Sacred Relic's shrapnel and Rinaldo T are neither melee nor ranged.
Jun-Ninja can block melee attacks. Joyo-Ninja can deflect and dodge ranged attacks.
==Damage==
Damage values are computed using the formula:
\text{Final damage} = \text{Base damage} \times \text{Character damage multiplier} \times \text{Target damage receive multiplier} \times \text{Type multiplier}
The used variables are explained in more depth below.
===Base damage===
\text{Base damage} = \text{Skill ATK multiplier}\times\text{ATK}+\text{Skill DMG},
where
* \text{Skill ATK multiplier} is the percentage listed in the used skill's description.
* \text{ATK} is the sum of ATK stats of the attacking battlesuit and her weapon and stigmata.
* \text{Skill DMG} is the flat damage listed on certain skills.
For example, consider White Comet's basic attack Meteor Kata. The first sequence deals "100% ATK of Physical DMG", so \text{Skill ATK multiplier}=1. Furthermore, Comet Kata reads "Physical DMG dealt by each sequence of the 4-sequence Basic ATK increases by 143.0", so \text{Skill DMG}=143.
===Character damage multiplier===
For summons, this is equal to 1. For players,
\text{Character damage multiplier} = (1+\text{Total DMG Multiplier})\times (1+\text{Element DMG Multiplier})\times \text{Critical multiplier},
where
* \text{Total DMG Multiplier} is the sum of the battlesuit's Total DMG multiplier stats, e.g., from stigmata.
* \text{Element DMG Multiplier} is the sum of the battlesuit's DMG stats that match the attack's element, e.g., Physical DMG for physical attacks.
* \text{Critical multiplier} is 1 for noncrits and 2+\text{Crit damage} for crits.
===Target damage receive multiplier===
\text{Target damage receive multiplier} = (1 + \text{Target Total DMG Multiplier})\times(1 + \text{Target element multiplier}) \times \text{Target element resistance multiplier}\times\text{Target defense multiplier},
* \text{Target Total DMG Multiplier} is the sum of Total DMG multiplier stats applied on the target by debuffs.
* \text{Target element multiplier} is the sum of element DMG bonuses applied on the target by debuffs, e.g., Blood Dance's Blood Drake.
* \text{Target element resistance multiplier} is determined by enemy type and cannot be affected by the player.
* \text{Target defense multiplier}=\begin{cases}1\text{ for elemental}\\\frac{1}{1+\frac{\text{DEF}}{20\times(\text{AttackerLevel}+15)}}\text{ for physical}\end{cases}, whereDmitry221060, A detailed look at the damage calculation in Honkai Impact 3rd, 2021. Available online, 2021.
** \text{DEF} is the target's DEF stat. Defense can be reduced with impair.
===Type multiplier===
Type multiplier is determined by the attacker's and target's types, which are either mecha, biologic, psychic or quantum. Mecha is strong against biologic, biologic is strong against psychic, and psychic is strong against mecha. Conversely, biologic is weak against mecha and so on. With this in mind, the type multiplier is given by
\text{Type multiplier}=\begin{cases}1.3\text{ if strong} \\ 0.7\text{ if weak} \\ 1\text{ otherwise} \end{cases} 
Quantum is neither strong nor weak against all types and hence has multiplier 1.
==Hidden damage stats==
Attacks can deal extra damage to shields or have force power.
===Shield Damage===
Shield Damage is based on at least 3 stats: Final Character Damage, Hit weight and Shield Damage Multiplier
\text{Shield Damage Multiplier} = (1 + \text{Damage to shield})
===Force Power===
Force Power depends on character attack velocity and weight.
Yamabuki and Divine Pray tag-in have highest force power in the game.
==Critical strike chance==
\text{Crit rate}=\frac{\text{CRT}}{\text{Level}\times5+75}\times 100%+\text{Bonus rate},
where:
* \text{CRT} is the sum of CRT stats of the attacking battlesuit and her weapon and stigmata.
* \text{Level} is the attacking battlesuit's level.
* \text{Bonus rate} is CRT added by skills (including leader skills) and buffs (e.g. Rowland 3 set).
For example, a level 80 battlesuit with 70 CRT from equipment will have 14.7% chance to crit.
