To calculate the Minimum Damage as shown in the figure above:
+
As mentioned earlier in [[#Damage Variance|Damage Variance]], weapons are divided into groups based on the formula used in the calculation:
 +
* '''Non-rare''' group consists of the following:
 +
** Weapons with {{rarity|1}} through {{rarity|6}} rarity.
 +
** Crafted weapons using less than Silver tier recipes.
 +
** Blue and Red Series of weapons.
 +
** Any weapon when using a non-primary ATK stat (e.g. Vibrace weapon's T-ATK).
 +
* '''Silver Craft''' group consists of any weapon crafted using Silver tier recipe.
 +
* '''Invade OT & Val''' group consists of said weapon series.
 +
* '''Rare''' group consists of other weapons not mentioned above.
  
* Non-rare weapons are defined as {{rarity|1}} through {{rarity|6}}, normal crafted weapons, and the Blue and Red Series of weapons.
+
Note that not all weapons have been thoroughly tested and there may be exceptions to the grouping and formula not yet discovered.
Weapons that were not mentioned are defined as Rare Weapons. Although Striking/Ranged Weapons and Techniques share a similar damage formula to that of non-rare weapons,
 
there's a growing number of differences that split them apart. However, not all weapons however have been thoroughly tested and may yield different exceptions to the formula.
 
  
* After the update on Oct 08, 2014, it was found that:
+
* As of Oct 08, 2014, it was found that:
** The weapons that shared the same formula as non-rare weapons were: [[Till Traitor]], [[Falclaw]], the Vibrace Weapon Series, [[Neidaryl]]. [[Dalz Varley]], and [[Helen Tramer]].
+
** The following weapons shared the same formula as '''Non-rare''' group: [[Till Traitor]], [[Falclaw]], Vibrace Weapon series, [[Neidaryl]]. [[Dalz Varley]], and [[Helen Tramer]].
** The weapons that shared the same forumla as rare weapons were: [[Rikauteri]], [[Biskedrop]], [[Madullard Varis]], and the Orbit Weapon Series.
+
** The following weapons shared the same formula as '''Rare''' group: [[Rikauteri]], [[Biskedrop]], [[Madullard Varis]], and Orbit Weapon series.
** The weapon that shared the same forumla as either Rare or Silver-crafted weapons was: [[Soul of Wopal]]. (Due to the Attack Power being so low, they were unable to verify what category the weapon followed)
+
** The following weapons shared the same formula as either '''Rare''' or '''Silver Craft''' group:: [[Soul of Wopal]]. (Due to the Attack Power being so low, they were unable to verify which group it was supposed to be.)
** Skills and other offensive abilities that are not bound by main-class usage include: Techniques, Snatch Step, Tool-related skills (Gravity Bomb, traps, etc), Ignition Skills (Such as Freeze Ignition), Mag Auto Actions, and Photon Blasts.
 
  
* The Invade OT and Val weapon series have their own damage modifiers.
+
* '''Grind Modifier''' is defined as the growth rate of weapon stats based on the current grind level of the weapon. For instance, a weapon of {{rarity|4}} at +10 has 160% of its original ATK, which is equal to 1.60 in decimal format. In this case, the Grind Modifier used in the formula becomes 1.60.
 
+
* As a reference, the following Weapon Modifier values can be calculated using the formula:  
* The Grind Level is defined as the current Grind Level of the weapon. For instance, a weapon of {{rarity|4}} at +10 is written as 160% of its original attack power. Thus 160% becomes 1.60 in decimal format.
+
** {{rarity|4}} - {{rarity|6}} +10 (Non-rare, Grind Modifier = 1.60): 30.0
 
+
** {{rarity|7}} - {{rarity|9}} +10 (Non-rare, Grind Modifier = 1.75): 37.5
* Weapon Modifier reference:  
+
** {{rarity|10}} Ex8 craft +10 (Silver Craft, Grind modifier = 1.90): 235.0
**DEX modifiers: {{rarity|4}} through {{rarity|6}} +10 is 30.0,  ★7-9 +10 is 37.5, and ★10 Ex8 +10 is 235.0
 
 
 
* It was often confusing to use the term "Minimum Attack Power" in the formula, so this variable was changed to "Effective Attack Power".

Shifta, Drinks, Team Tree Buffs, etc can only be applied to the "Base Stats + Mag + Attack Stat Ups, etc" section on the figure above.
+
Fraction of stats caused by calculations from buffs are kept in calculation, even if numbers are rounded before being displayed in-game. Thus, when calculating damage, do not round off decimal values, as they can become significant under very high multipliers.
This includes the Player's Base Stats, Mag Stats and Skills, and Stat Up skills (Such as S-ATK Up or R-ATK Up).
 
"Stat Up" does not include skills that give you a dynamic stat bonus such as Photon Flare.
 
  
A fraction of the stats caused by Buffs are preserved, even if you cannot view them in-game. Under very high multiplier conditions, damage cannot be reproduced without taking this fractional part into account.
+
Based on the figure above, '''Base Stats, Mag, Stat Ups, etc.''' includes:
 +
* The player's base stats.
 +
* Mag stats.
 +
* Stat Up skills (e.g. S-ATK Up, R-ATK Up, T-ATK Up).
 +
** Mag-based stats skills such as Braver Mag are also included.
 +
** Skills which increase stats dynamically such as Photon Flare are not included.
  
Additionally, not only does Shifta increase a pet's attack power, but it also affects the affixed special abilities and set bonus (if available) of your units, as well as a Pet Bonus Stats.
+
Stat buffs e.g. Shifta, Drinks, Team Tree Buffs can only be applied to the "Base Stats, Mag, Stat Ups, etc." section.
 +
As an exception, Shifta can affect Special Abilities on Units, Set Bonuses, and Pet Bonus Stats (Stats acquired from feeding, AKA Plus Values/プラス値).
 +
It is not known whether Timed Abilities Stat Bonuses are affected by Shifta.
  
Thus the formula calculation for Shifta is <code>{ (Base Stats + Mag + Attack Stat Ups) × Team Tree × Shiftaride + Unit Affixes + Pet Bonus Stats } × Shifta</code>.
+
To put it simply, the formula to calculate Attack Power with Shifta is:
 +
 
 +
<code>{ (Base Stats + Mag + Stat Ups) × Photon Tree Buff × Shifta Drink + Special Abilities on Units + Set Bonuses + Pet Bonus Stats } × Shifta</code>

=== The Effect of Shifta on Pets ===
The effects of Shifta on Pets works differently than it does on normal players, thus it's insufficient to just multiply a Pet's Attack Power by Shifta's multiplier.

The effects of Shifta on Pets have certain specific exceptions compared to non-Pet scenarios.
 +
 
 +

 +
* The player's increased Attack Power from Shifta <span class="text-danger">has no effect on the Pet's damage output. Shifta must be applied on the Pet to take effect.</span>
 +
 
 +
Thus, expanding from the above section, the formula for Shifta becomes:

+
<code>{ (Base Stats + Mag + Stat Ups) × Photon Tree Buff × Shifta Drink + Special Abilities on Units + Set Bonuses + Pet Bonus Stats + Support Roll bonus } × Shifta</code>
** A Pet's base stats (not the Pet Bonus Stats) <strong>are not affected by Shifta.</strong>
 
** The Attack Boost granted by Cookies <strong>are not affected by Shifta.</strong>
 
** A Takt's Attack Power is <strong>not affected by Shifta.</strong>
 
** It is not known whether Timed Abilities Stat Bonuses are affected by Shifta.
 
* Using Switch Skills will cause the Attack Power type to change on Units, as noted by the above section [[Damage_Calculation#Damage_Type_Reference|Damage Type Reference]]. For instance, if one were to have Switch Shoot active, not only will the Attack Power change from T-ATK to R-ATK, but the if the Unit equipped has any R-ATK affixes or a set bonus with R-ATK, it will use those values instead of the T-ATK values.
 
* A Player's Attack Power Boost from Shifta <strong>has no effect on the Pet itself. Must be applied on to the Pet.</strong>

Damage Composition and Variance

Damage Composition

PSO2's damage is divided into the following:

  • Player Damage (Base Stats, Mag Stats, Special Abilities, etc.)
  • Weapon Element Damage
  • Weapon Damage

In the case of Techniques, "Weapon Element damage" is not applicable.

Damage variance only applies to Weapon Damage. For this reason, there is no damage variance when attacking without a weapon equipped (AKA bare-handed). The minimum value of Weapon Damage always ranges between 10% and 90%. When under conditions which are too good or too bad outside the range of 10-90%, the resulting minimum Weapon Damage will always be capped within 10%-90%. A critical hit removes this variance, resulting in 100% of Weapon Damage being applied.

Maximum damage on a critical hit (Criticals are shown as blue numbers in-game):

Player Damage
Weapon Element Damage
Weapon Damage 100%

Non-critical damage under the best conditions:

Player Damage
Weapon Element Damage
Minimum Weapon Damage 90%
Variance

Non-critical damage under the worst conditions:

Player Damage
Weapon Element Damage
Min. 10%
Variance

As shown above, the damage variance only applies to Weapon Damage, thus it is less evident when observing only the total damage. Since Techniques do not have Weapon Element Damage, it is slightly easier to notice the damage variance compared to other types of attacks.

It should also be noted that Summoner Pets have a wide damage variance. The exact reasoning is unknown, but it's presumed they follow the non-rare OT damage formula. More on that later in this page.

Damage Variance

The above section can be summarized as the following table:

Maximum Damage
Player Damage Weapon Element Damage Weapon Damage 100%
Minimum Weapon Damage Damage Variance

To determine the minimum weapon damage, there are two broad categories.

  • Rare weapons (7 and above) → fixed 90%
    • Note that while it was previously possible to have less than 90%, it is no longer the case currently.
    • The Invade OTs and Val series have the minimum weapon damage formula similar to that of "Non-rare Crafted Weapons".
  • Non-rare, crafted weapons, Invade OTs, Val series → calculated based on the difference in DEX between the player and the enemy, weapon rarity, and weapon grind.
    • Silver tier or higher crafts, Invade OTs, Val series → calculated minimum weapon damage has a large modifier, resulting in generally higher minimum weapon damage.
    • Crafts that are below Silver tier, common, uncommon, Red and Blue weapons, non-primary ATK stats (e.g. Vibrace weapon's T-ATK) → calculated minimum weapon damage has a small modifier, resulting in generally less minimum weapon damage.

In the case of non-rare, the value of minimum weapon damage is not dependent on weapon attack. If we were to compare between a weapon with 500 attack and another weapon with 1000 attack, under the same surrounding conditions (same difference in DEX between the player and the enemy, same weapon rarity, same level of weapon grind), the calculated minimum weapon damage of both weapons would still be the same.

See Minimum Damage for more details on minimum weapon damage calculation.

Damage Calculation Formula

Damage Type Reference

When calculating damage, there is an implied understanding to what the damage type an attack is. There are many different attacks with varying properties affecting how damage is calculated.

Key:

Attack Power
The ATK stat from which the damage is calculated. Increasing the specified ATK stat will increase damage. Other ATK stats have no effect.
Defense Power
The enemy's DEF stat against which the damage is calculated. The higher the specified DEF stat, the less damage can be dealt to the enemy. Similarly, other DEF stats have no effect.
Weapon Element Damage
The ATK stat from which the Weapon Element Damage is calculated. This is dealt as elemental damage and is affected by elemental Part Boost multiplier. For example, when attacking an enemy with fire weakness with a fire element weapon, the Weapon Element Damage is increased by the enemy's fire Part Boost multiplier.
Part Boost
The specific type of Part Boost multiplier used. This differs for each part on the body of the enemy hit by the attack. If the Part Boost is specified as "Ranged", the damage will be affected by headshot multiplier when attacking the head of an enemy. If the Part Boost is specified as "Elemental Attribute", the damage is considered as elemental attribute damage and is affected by elemental Part Boost multiplier. Note that this is independent from Weapon Element Damage which is always affected by elemental Part Boost multiplier.
Final Attack Type
The final damage type of the attack. This is used to determine the effects of class skills, Skill Rings, Potentials, etc. For example, if the Final Attack Type is "Ranged", the damage will be boosted by Ranger's skill "Weak Hit Advance".

Maximum Damage

Maximum Damage
Player Damage Weapon Element Damage Weapon Damage 100%
Minimum Weapon Damage Damage Variance

To calculate the Maximum Damage as shown in the figure above:

  • Replace Attack Power, Defense Power, and Part Boost in the formula with their respective values.
  • Weapon Attack Power refers to the relevant Attack Power of the weapon, excluding Special Abilities (affixes).
  • 1.05 is from the latent 5%, colloquially referred to as the "Mystery Multiplier" in the Japanese community.
    • This multiplier did not exist during PSO2's intial Japanese launch, however its existence was confirmed with the release of subclasses.
    • With the exception of a few attacks, all damage is eventually affected by it. The only exception currently confirmed is the direct damage from Zonde.
    • On a side note, when calculating enemy's attack multiplier based on red damage numbers when hit by an enemy's attack. Dividing the damage by 1.05 reveals a rounder value, suggesting that there is a high probability that even the enemies themselves are affected by this multiplier.
  • Total Multiplier is the product of all the relevant damage multipliers except Part Boost. This includes the 1.05, PA notation, Skills, Potential Abilities, etc.
  • For Pets, use Pet's Attack Power instead of weapon's.
    • Pet's default base ATK → Weapon Attack Power
    • Pet's Bonus Stats → Special Abilities (affected by Shifta).
    • Stats from Candies → Special Abilities (unaffected by Shifta).
    • Interactions between Pet stats and Shifta will be explained in detail later in Applying Buffs.
Damage Source = (Total Attack Power - Defense Power) x Part Boost

Weapon Element Damage = Weapon Attack Power x Element Percentage x Elemental Part Boost
(If Technique: Weapon Element Damage = 0)

Total Multiplier = 1.05 x PA Notation x Skill Multiplier x Potential Multiplier etc.

Maximum Damage = (Damage Source + Weapon Element Damage) ÷ 5 × Total Multiplier

Advanced Calculation (same formula but distributed into parts): Show/Hide

Player Damage = (Total Attack Power from Base Stats, Units, Mag, Special Abilities, etc. ÷ 5) × Part Boost × Total Multiplier

Weapon Attack Damage = (Weapon Attack Power ÷ 5) x Part Boost x Total Multiplier

Weapon Element Damage = (Weapon Attack Power x Element Percentage ÷ 5) x Elemental Part Boost x Total Multiplier
(If Technique: Weapon Element Damage = 0)

Defense Damage Reduction = (Defense Power ÷ 5) × Part Boost × Total Multiplier
		
Maximum Damage = Player Damage + Weapon Attack Damage + Weapon Element Damage - Defense Damage Reduction

Minimum Damage

Minimum Weapon Damage Damage Variance

As mentioned earlier in Damage Variance, weapons are divided into groups based on the formula used in the calculation:

  • Non-rare group consists of the following:
    • Weapons with 1 through 6 rarity.
    • Crafted weapons using less than Silver tier recipes.
    • Blue and Red Series of weapons.
    • Any weapon when using a non-primary ATK stat (e.g. Vibrace weapon's T-ATK).
  • Silver Craft group consists of any weapon crafted using Silver tier recipe.
  • Invade OT & Val group consists of said weapon series.
  • Rare group consists of other weapons not mentioned above.

Note that not all weapons have been thoroughly tested and there may be exceptions to the grouping and formula not yet discovered.

  • As of Oct 08, 2014, it was found that:
  • Grind Modifier is defined as the growth rate of weapon stats based on the current grind level of the weapon. For instance, a weapon of 4 at +10 has 160% of its original ATK, which is equal to 1.60 in decimal format. In this case, the Grind Modifier used in the formula becomes 1.60.
  • As a reference, the following Weapon Modifier values can be calculated using the formula:
    • 4 - 6 +10 (Non-rare, Grind Modifier = 1.60): 30.0
    • 7 - 9 +10 (Non-rare, Grind Modifier = 1.75): 37.5
    • 10 Ex8 craft +10 (Silver Craft, Grind modifier = 1.90): 235.0
Weapon Modifier =
        Non-rare group:
                50 × (Grind Modifier - 1)
        Silver Craft group (Twin Daggers, Double Sabers, Gunslashes):
                50 + 100 × (Grind Modifier - 1)
        Silver Craft group (Other Weapons):
                100 + 150 × (Grind Modifier - 1)
        Invade OT & Val group:
                150 + 200 × (Grind Modifier - 1)
        Pets:
                -50
                (If self-inflicted damage, use 0 instead)

Guaranteed Minimum Attack = (Player DEX x PA DEX Modifier - Enemy DEX + Weapon Modifier) x 2

90% Cap = Weapon Attack Power x 90%
10% Cap = Weapon Attack Power x 10%

Effective Attack Power = 
        Rare group:
                90% Cap
        Else:
                90% Cap if Guaranteed Minimum Attack > 90% Cap
                10% Cap if Guaranteed Minimum Attack < 10% Cap
                Guaranteed Minimum Attack otherwise

Minimum Weapon Damage = Effective Attack Power ÷ 5 × Part Boost x Total Multiplier

Applying Buffs

Maximum Damage
Player Damage, Mag Stats | Weapon Element Damage | Weapon Damage 100%
Base Stats, Mag, Stat Ups, etc. | Special Abilities | Photon Flare, etc. | Minimum Weapon Damage | Damage Variance

Fraction of stats caused by calculations from buffs are kept in calculation, even if numbers are rounded before being displayed in-game. Thus, when calculating damage, do not round off decimal values, as they can become significant under very high multipliers.

Based on the figure above, Base Stats, Mag, Stat Ups, etc. includes:

  • The player's base stats.
  • Mag stats.
  • Stat Up skills (e.g. S-ATK Up, R-ATK Up, T-ATK Up).
    • Mag-based stats skills such as Braver Mag are also included.
    • Skills which increase stats dynamically such as Photon Flare are not included.

Stat buffs e.g. Shifta, Drinks, Team Tree Buffs can only be applied to the "Base Stats, Mag, Stat Ups, etc." section. As an exception, Shifta can affect Special Abilities on Units, Set Bonuses, and Pet Bonus Stats (Stats acquired from feeding, AKA Plus Values/プラス値). It is not known whether Timed Abilities Stat Bonuses are affected by Shifta.

To put it simply, the formula to calculate Attack Power with Shifta is:

{ (Base Stats + Mag + Stat Ups) × Photon Tree Buff × Shifta Drink + Special Abilities on Units + Set Bonuses + Pet Bonus Stats } × Shifta

The Effect of Shifta on Pets

The effects of Shifta on Pets have certain specific exceptions compared to non-Pet scenarios.

  • Attack Power bonus from Support Roll is affected by Shifta.
  • The Pet's base stats (not Pet Bonus Stats) are not affected by Shifta.
  • Pet Bonus Stats is affected by Shifta.
  • The Attack Boost granted by Cookies are not affected by Shifta.
  • Takt's Attack Power is not affected by Shifta.
  • Using Switch Skills will cause the referenced Attack Power to change, as noted in Damage Type Reference. For instance, if Switch Shoot is active, the referenced Attack Power will change from T-ATK to R-ATK, then R-ATK values from Special Abilities on equipped Units and Set Bonuses will be used instead.
  • The player's increased Attack Power from Shifta has no effect on the Pet's damage output. Shifta must be applied on the Pet to take effect.

Thus, expanding from the above section, the formula for Shifta becomes:

{ (Base Stats + Mag + Stat Ups) × Photon Tree Buff × Shifta Drink + Special Abilities on Units + Set Bonuses + Pet Bonus Stats + Support Roll bonus } × Shifta

Criticals and Expected Values

When you deal critical damage, the damage will show up in-game as a blue damage number. The default critical rate is estimated to be 5%.

The higher the critical rate, the higher the average damage will be. To calculate the expected value considering the critical rate, the following is recommended:

Mid-range = (Maximum Value + Minimum Value) ÷ 2
Expected Value = Mid-range + Critical Rate x (Maximum Value - Mid-range)

And taking critical damage bonuses (e.g. Critical Strike) into account:

Mid-range = (Maximum Value + Minimum Value) ÷ 2
Expected Value = Mid-range + Critical Rate × (Maximum Value x Critical Damage bonus - Mid-range)
