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.

Damage Variance

The above section can be summarized as the following table:

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

To determine the minimum 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 same minimum damage equivalent to "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 damage has a large modifier, resulting in generally higher minimum damage.
    • Crafts that are below Silver tier, common, uncommon, Red and Blue weapons, non-main primary types (Vibrace Weapon's tech power) → calculated minimum damage has a small modifier, resulting in generally less minimum damage.

In the case of non-rare, the value of minimum 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 damage of both weapons would still be the same.

See Minimum Damage for more details on minimum 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".

Minimum 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 extra 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 the section regarding 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 Damage Damage Variance


As mentioned earlier in Damage Variance, minimum damage can be calculated as the following: 

Weapon Modifier =
	For non-rare weapons or Iro/Steel Crafts:
		50 × (Grind Level - 1)
	For Silver Crafts (Twin Daggers, Double Sabers, Gunslashes):
		50 + 100 × (Grind Level - 1)
	For Silver Crafts (Other Weapons):
		100 + 150 × (Grind Level - 1)
	For Invade OT, Val Weapons:
		150 + 200 × (Grind Level - 1)
	For 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 = 
	If Rare Weapon: 
		90% Cap
	If non-rare:
		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
