Important Note
The formulas listed on this page are a translation of data obtained from analyzing the game in its vanilla state. Therefore, if you use some impossible combinations that are only possible via hacking (e.g. using Twogun with ShootingMastery), the calculations may be skewed from the ingame results.
Parameter Definitions
WEA
 The attack power of the weapon you’re using, including compensation from any and all WEA Up
wWeight (Weapon Weight)
 The weight of the weapon you’re using
STR, QUI, INT, WIL, PSY, VIT, rHP (remaining HP)
 The final status of the character, including compensation from any and all stat changes (i.e. buffs and debuffs)
Weight
 The weight of the character
DEF
 The final defensive strength of the target, including compensation from any and all DEF Up/Down
 Refers to the defense of the same attribute as the tech being used
 If the tech has more than one attribute, it refers to the defense of the attribute with the lowest value
 If the attack is used after the first move of a combo, the defense is 0
PSY, VIT, mHP (maximum HP), rHP (remaining HP)
 The final status of the target, including compensation from any and all stat changes
Weight
 The weight of the target
bPow (Basic Power)
 The basic amount of damage for a tech that isn’t affected by status effects or other factors
 Related page: Technique List
Growth
 The higher this value is, the more damage you deal
 This includes combos
 Related page: Technique List
cCost (Consumption Cost)
 The WP/JP to be spent
 Reflects the actual cost, including factors increased or decreased cost (e.g. SoulRune, Overdrive)
cAmmo (Ammo Cost)
 The number of bullets consumed by the gun you’re using
 When using Twogun, the ammo consumption of the secondary gun isn’t affected
 Reflects the actual bullet consumption
 If ammo cost is 5 but bullet count is 3, ammo cost is now 3
Dist (Distance)
 The distance between the attacker and the target
 There is no way to check this directly in the game
cFacing (Orientation Correction)
 Note that the visual orientation of the character doesn’t always match the orientation parameter of said character (Sprite Facing and Real Facing)
cCombo (Combo Correction)
 If the attack is used after the first move of a combo, it takes a value of +100. Otherwise, the value is 0
Battlefield and Mystic Multipliers
 If a Battlefield Peace Divisor is enabled, then the final attack damage is multiplied by 0.25
 If both the attack and the target are Mystics (excluding Mesarthim), then the final attack damage is multiplied by 0.25
 In all other cases, the final attack damage is multiplied by 1.0
Twogun Multiplier
 If the attacker has Twogun and two or more guns equipped and the tech used corresponds to Twogun, then the final attack damage is multiplied by 1.75
 In all other cases, the final attack damage is multiplied by 1.0
ShootingMastery Multiplier
 If the attacker has ShootingMastery equipped but not Virus, then the final attack damage is multiplied by 1.5
 In all other cases, the final attack damage is multiplied by 1.0
CombatMastery Multiplier
 If the attacker has CombatMastery equipped but not Virus, then the final attack damage is multiplied by 1.5
 In all other cases, the final attack damage is multiplied by 1.0
nHits (Number of Hits)
 The number of times you successfully hit your target when using a Rapid Fire Damage I or Rapid Fire Damage II tech
 The number of hits depends on cAmmo. However, while nHits for Rapid Fire Damage II = cAmmo of all guns, nHits for Rapid Fire Damage I = cAmmo of the primary gun
 This means that nHits with CrossShot (Rapid Fire Damage II) will increase with Twogun equipped, but not for Crosshair (Rapid Fire Damage I)
 In addition, nHits is limited to 10, so even if you use CrossShot with Twogun equipped, nHits will not exceed 20
Enemy Multiplier
 If the attacker is an enemy character, then the final attack damage is multiplied by 0.33…
 If the attacker is an ally character, then the final attack damage is multiplied by 1.0
MagiSphere Multiplier
This parameter is exclusively for the Duel against Rouge in Blue’s scenario
 If the tech used does not match the MagiSphere, then the final attack damage is multiplied by 0.25
 If they do match, then the final attack damage is multiplied by 1.0
Normal RNG
 A random integer with a minimum value of 0 and a maximum value of 65535
 Related page: RNG
Calculation Rules
 In parentheses, calculations are performed in order from left to right, with priority given to modulo calculations, and any values after the decimal point are truncated before the next calculation
 All calculations that are underlined do not get truncated
 If subtraction calculations output a negative number, the output is corrected to 0
 Example: “X = (10 – 22) x 3 + 5” becomes “X = 5”
 “A (mod B)” means “mod A / B”
Tech/Spell Application: Sword Techniques
Basic Damage Formula:
BaseDamage = A + B + C + D + E + F + G

 A = bPow * 4
 B = STR² * WEA * 100 ÷ 32 * Growth ÷ (STR² + 1600)
 C = (WEA – DEF) * (50 + STR + wWeight) ÷ 32
 D = WEA * Growth
 E = (Growth – 2) * (200 – Dist) ÷ 8
 F = (Growth – 2) * Combo Correction
 G = cFacing
Final Damage Formula:
FinalDamage = N + M

 N = n * CombatMastery Multiplier * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * CombatMastery Multiplier * Enemy Multiplier
Additional Explanation:
Damage is increased by WEA and STR with this formula
Tech/Spell Application: Gun Techniques and Specific AmmoBased Heavy Weapon Techniques
Basic Damage Formula:
BaseDamage = A + B + C + D + E + F

 A = bPow * (1 + cAmmo) * 4
 B = WIL² * WEA * 100 ÷ 32 * Growth ÷ (WIL² + 1600)
 C = (WEA – DEF) * (100 + WIL) ÷ 32
 D = WEA * Growth
 E = (Growth – 2) * Combo Correction
 F = cFacing
Final Damage Formula:
FinalDamage = N + M

 N = n * Twogun Multiplier * ShootingMastery Multiplier * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * Twogun Multiplier * ShootingMastery Multiplier * Enemy Multiplier
Tech/Spell Application: FocusShot and CrossHair (Rapid Fire Damage I)
Basic Damage Formula:
BaseDamage = A + B + C + D

 A = bPow * 4
 B = WIL² * WEA * 100 ÷ 32 * Growth ÷ (WIL² + 1600)
 C = (WEA – DEF) * (100 + WIL) ÷ 32
 D = (Growth – 2) * Combo Correction
Final Damage Formula:
FinalDamage = N + M

 N = n * nHits * ShootingMastery Multiplier * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * nHits * ShootingMastery Multiplier * Enemy Multiplier
Additional Explanation:
Compared to the formula described below, this one has higher potential because it takes Combo Correction into account. However, this does not get a multiplier from Twogun, so it’s very inferior in terms of general strength.
Tech/Spell Application: CrossShot (Rapid Fire Damage II)
Basic Damage Formula:
BaseDamage = A + B + C

 A = bPow * 4
 B = STR² * WEA * 100 ÷ 32 * Growth ÷ (STR² + 1600)
 C = (WEA – DEF) * (50 + STR + wWeight) ÷ 32
Final Damage Formula:
FinalDamage = N + M

 N = n * nHits * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * nHits * Enemy Multiplier
Supplementary Explanation:
Even though this is a gun technique, its damage depends on STR, so it’s a bit troublesome in terms of growth. In addition, since there’s no Combo Correction, the benefits of using this in a combo are limited.
Tech/Spell Application: Specific RayBased Heavy Weapon Techniques
Basic Damage Formula:
BaseDamage = A + B + C + D

 A = bPow * (1 + cAmmo) * 4
 B = WIL² * WEA * 100 ÷ 32 * (Growth + b) ÷ (WIL² + 1600)
 b = 2 if the attacker is a mec; otherwise, b = 0
 C = (WEA – DEF) * (100 + WIL) ÷ 32
 D = WEA * (Growth – 1)
Final Damage Formula:
FinalDamage = N + M

 N = n * ShootingMastery Multiplier * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * ShootingMastery Multiplier * Enemy Multiplier
Additional Explanation:
Damage is slightly increased if the attacker is a mec. In addition, since there’s no Combo Correction, the benefits of using this in a combo are limited.
Tech/Spell Application: Martial Arts (excluding throwing techs), and Others
Basic Damage Formula:
BaseDamage = A + B + C + D + E + F

 A = bPow * 4
 B = STR² * b * 100 ÷ 32 * Growth ÷ (STR² + 1600)
 b = (STR + QUI + VIT + 50) ÷ 4
 C = QUI² ÷ 16
 D = (Growth – 2) * (220 – Dist) ÷ 8
 E = (Growth – 2) * Combo Correction
 F = cFacing
Final Damage Formula:
FinalDamage = N + M

 N = n * CombatMastery Multiplier * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * CombatMastery Multiplier * Enemy Multiplier
Tech/Spell Application: Martial Arts (throwing techs), MightyCyclone, SwingDDT, Vandal Flip, PowerBomb
Basic Damage Formula:
BaseDamage = A + B + C + D + E + F

 A = bPow * 4
 B = STR² * b * 100 ÷ 32 * Growth ÷ (STR² + 1600)
 b = (STR + QUI + VIT + 50) ÷ 4
 C = QUI² ÷ 16
 D = (Weight + VIT) * Growth
 E = (Growth – 2) * Combo Correction
 F = cFacing
Final Damage Formula:
FinalDamage = N + M

 N = n * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * Enemy Multiplier
Tech/Spell Application: DSC
Basic Damage Formula:
BaseDamage = A + B + C + D

 A = bPow * nHits²
 B = STR² * b * 100 ÷ 32 * Growth ÷ (STR² + 1600)
 b = (STR + QUI + VIT + 50) ÷ 4
 C = QUI² ÷ 16
 D = (Weight + VIT) * Growth
※BaseDamage should be ≦ 10,000
Final Damage Formula:
FinalDamage = N + M

 N = n * nHits
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * nHits
DSC’s nHits Formula:
NumberOfMoves = Normal RNG (mod N) + 2

 N = (mHP – rHP) * 3 ÷ (mHP + 1) + {(STR + QUI + VIT + 60) ÷ 4 – VIT} ÷ 20 + 2
※nHits must be ≦ 4
Additional Explanation:
DSC is often referred to as a “Single Person Combo” attack, but in reality it’s just a single attack. This means that it doesn’t ignore defensive values and can’t be combo’d into other moves, making it difficult to deal damage to enemies with high Blunt resistance.
The following gives a rough idea of nHits’ probability based on the enemy’s stats:
Tech/Spell Application: Monster Techs (breath), and Others
Basic Damage Formula:
BaseDamage = A + B + C

 A = bPow * 4
 B = (b + VIT / 2 + Weight) * Growth
 b = rHP ÷ 8 is attacker is an ally; b = rHP ÷ 16 if attacker is an enemy. However, b ≤ 80
 C = Normal RNG (mod Number of Learned Techniques)
Final Damage Formula:
FinalDamage = N * Enemy Multiplier

 N = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
Additional Explanation:
The less rHP you have, the less damage you will deal. The most influential variable is Weight, but since the limit is 99, there’s no point in making the character excessively heavy. Also, since there’s no Combo Correction, there’s little benefit from using this in a combo.
Tech/Spell Application: Spells, and Others
Basic Damage Formula:
BaseDamage = A + B + C + D + E

 A = bPow * 4
 B = WIL² * b * 100 ÷ 32 * Growth ÷ (WIL² + 1600)
 b = (INT + WIL + PSY + 40) ÷ 4
 C = PSY² ÷ 16
 D = (INT + WIL + PSY + 100) ÷ 4 * 2 * cCost
 E = (Growth – 2) * Combo Correction
Final Damage Formula:
FinalDamage = N + M

 N = n * Enemy Multiplier * MagiSphere Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * Enemy Multiplier * MagiSphere Multiplier
Additional Explanation:
WIL is the most important factor in tech damage, but the effects of PSY and INT cannot be ignored. It’s worth noting that variable D increases with cCost. This is where the strength of Tower lies. Due to space limitations, I didn’t include it in the list of techs, but techs that deal damage based on cCost have a chance of “FinalDamage/11” to remove the damagereducing Heavenly Peace Divisor effect caused by Fool. (Since the damage is rarely less than 11, it’s almost guaranteed to be removed)
Tech/Spell Application: Bloodsucker, Grasp, GhostTouch, FireKiss, HPDrain, BloodSucker, and Lord’sDinner
Basic Damage Formula:
BaseDamage = A + B + C + D + E

 A = bPow * 4
 B = WIL² * b * 100 ÷ 32 * Growth ÷ (WIL² + 1600)
 b = (INT + WIL + PSY + 40) ÷ 4
 C = PSY² ÷ 16
 D = cCost² ÷ 2
Final Damage Formula:
FinalDamage = N + M

 N = n * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 11)
 N = n * Enemy Multiplier
Additional Explanation:
There are some differences, such as the lack of Combo Correction, but it’s roughly the same as magic spell damage. The amount of damage you deal will be the amount of HP you restore.
Tech/Spell Application: RavaShot
Basic Damage Formula:
BaseDamage = A + B + C

 A = bPow * 4
 B = WIL² * PSY * 100 ÷ 32 * Growth ÷ (WIL² + 1600)
 C = PSY² ÷ 16
Final Damage Formula:
FinalDamage = N + M

 N = n * Enemy Multiplier
 n = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques)
 N = n * Enemy Multiplier
Additional Explanation:
Damage is increased if the target’s PSY is high. The only technique that this applies to is RavaShot. Despite the fact that there’s a special formula just for RavaShot, it can only be used by Arachne, a boss exclusive to Red’s scenario.
Tech/Spell Application: ChaosStream
Basic Damage Formula:
BaseDamage = A if attacker is an ally
BaseDamage = B if attacker is an enemy

 A = (bPow + PSY) * {Normal RNG (mod Growth + 1) + 1} * P * Q
 B = PSY * {Normal RNG (mod 5) + 1} * Q
 P = 1 if MagiSphere is Time; otherwise, P = 2
 Q = 2 if attacker is in OverDrive; otherwise, Q = 1
Final Damage Formula:
FinalDamage = N + M

 N = {BaseDamage * (128 – VIT ÷ 4 – DEF) ÷ 128 – DEF} * Battlefield and Mystic Multipliers
 M = Normal RNG (mod Number of Learned Techniques + 101)
Additional Explanation:
This formula is very different when used by an ally and when used by an enemy. Either way, the damage isn’t consistent. It also has a hidden feature that doubles damage when used in OverDrive.
