Damage Formula (PSO2)

Information here was translated directly from [https://pso2.swiki.jp/index.php?ダメージ計算] and will require some level of proofreading.

Damage Composition and Variance

Damage Composition

PSO2's damage is divided into parts: "Normals, Mag, Special Abillities, etc damage"; "Weapon Type damage"; and "Weapon Damage". In the case of Techniques, "Weapon Type damage" is not applicable.

Damage variance only occurs in the "Weapon Damage" section. For this reason, there is no damage variance in the bare-handed strikes and the bare-handed technique casting.

Thus the minimum damage a weapon can do is no less than 10%, no matter how bad the conditions are, and the highest damage of weapons can be cannot exceed 90% of the damage variance even under the best conditions, and vice versa.

Maximum Damage + Criticals (Criticals are shown as blue numbers in-game):
Normals, Mag, Special Abillities, etc | Weapon Type | Weapon Damage 100%

Damage under the best conditions:
Normals, Mag, Special Abillities, etc | Weapon Type | Weapon Damage 90%

Damage under the worst conditions:
Normals, Mag, Special Abillities, etc | Weapon Type | Weapon Damage 10%

The damage variance ratio is 10-90% for Weapon performance, thus the damage variance in the total damage is smaller. Since Techniques do not have Weapon Type damage, you can easily see the damage variance than you would normally with Striking and Ranged damage types.

If the conditions are either favorable or worst exceed the ranges of 10% to 90%, then the cap will be 10% and 90% respectively.

Damage Variance

Above section as summarized:

Maximum Damage
Normals, Mag, Special Abillities, etc	Weapon Type	Weapon Damage 100%
		Minimum Damage	Damage Variance

There are three ways to determine the minimum damage of weapons.

• Rarity → fixed 90% (Should be noted that it was previously possible to obtain less than 90% in damage variance, however it is impossible to do so now)
  The Invade OTs and Val series have the same minimum damage equivalent to "Non-rare Crafted Weapons".

• Non-rare crafts, Invade OTs, Val series → Variance calculated by the Dex difference between the player, enemy, weapon rarity and weapon grind.
  • Silver tier crafts → damage variance is boosted by a large amount.
  • Crafts that are not Silver tier, common, uncommon, red and blue weapons, non-main damage type (Vibrace Weapon's tech power) → damage variance is the minimum amount.
  • Invade OTs, Val series → minimum damage variance is wider spread.

With rare weapons, the damage variance is fixed at 90%.

In the case of non-rare crafts, minimum damage is not dependant on the weapon attack power. Even if you have a weapon with 500 to 1000 attack power, even under the best circumstances (Weapon fully enhanced to its maximum, DEX between you and the enemy are the same, high weapon rarity), you will still deal the minimum amount of damage.

Damage Calculation Formula

Notice: The calculation formula is based off of information that can be verified in-game, not from any official sources.

In the event that the damage exceeds 1 million, even if you've factored in the variances introduced by buffs, craft mastery, etc, the final damage tally will be mismatched. In this case, you can match your critical (blue) damage by multiplying the coefficient of Shifta and/or any Drinks (if used) with that of your total combined attack power.

The enemy's defensive power is normally an integer, however the decimals introduced by a barrier or infection core are preserved as part of the multiplier of its defensive power.

Damage Type Reference

When calculating damage, there is an implied understanding to what the damage type an attack is.

There are several PAs and attacks that differ in various ways on how they output damage.
