Damage

Damage formula:

damage for this card =
(01)    servantAtk
(02)    * npDamageMultiplier
(03)    * {firstCardBonus + [cardDamageValue * max(1 + cardMod, 0)]}
(04)    * classAtkBonus
(05)    * triangleModifier
(06)    * attributeModifier
(07)    * randomModifier
(08)    * 0.23
(09)    * max(1 + atkMod - defMod, 0)
(10)    * criticalModifier
(11)    * extraCardModifier
(12)    * max(1 - specialDefMod, 0)
(13)    * max([1 + powerMod + selfDamageMod + (critDamageMod * isCrit) + (npDamageMod * isNP)], 0.001)
(18)    * max(1 + damageSpecialMod, 0.001)
(14)    * [1 + ((superEffectiveModifier - 1) * isSuperEffective)]
(15)    + dmgPlusAdd
(16)    + selfDmgCutAdd
(17)    + (servantAtk * busterChainMod)

damage = Math.Floor(Math.Max(damage, 0))

Mapping of damage formula terms to buff actions:

• cardMod = actor.commandAtk - target.commandDef
• atkMod = actor.atk
• defMod = target.defence or target.defencePierce if it's a defence piercing NP
• specialDefMod = target.specialdefence
• powerMod = actor.damage + actor.damageIndividuality + actor.damageIndividualityActiveonly + actor.damageEventPoint
• selfDamageMod = target.selfdamage
• critDamageMod = actor.criticalDamage
• npDamageMod = actor.npdamage
• damageSpecialMod = actor.damageSpecial
• superEffectiveModifier = function Correction value
• dmgPlusAdd = actor.givenDamage
• selfDmgCutAdd = target.receiveDamage

Other constants lookup:

• npDamageMultiplier: only applies to NP card, 1 otherwise
• firstCardBonus, cardDamageValue:
  • firstCardBonus: NiceCard.card.order.addAtk
  • cardDamageValue: NiceCard.card.order.adjustAtk
• classAtkBonus: NiceClassAttackRate.class
• triangleModifier: NiceClassRelation.actor.target
• attributeModifier: NiceAttributeRelation.actor.target
• criticalModifier: NiceConstant.CRITICAL_ATTACK_RATE = 2 (only applies if critical, 1 otherwise)
• busterChainModifier: NiceConstant.CHAINBONUS_BUSTER_RATE = 0.2 if buster card in buster chain, 0 otherwise
• extraCardModifier:
  • NiceConstant.EXTRA_ATTACK_RATE_GRAND = 3.5 if it's a color brave chain
  • NiceConstant.EXTRA_ATTACK_RATE_SINGLE = 2 otherwise
  • 1 if not extra card
