Physical damage
To calculate physical damage (i.e. any damage not resulting from a fire/electric special attack or a Technique):
1. Begin by calculating the equipment ATP (EA):
EA = [minWA + (Grind x 2) + FA + BaA] x [ATR + 1.0]
- minWA = Weapon minimum possible ATP
- FA = Frame ATP
- BaA = Barrier ATP
- ATR = Weapon attribute %
2. Next, calculate the bonuses from 
Shifta (SA):
SA = [BA x Shifta] + [(MWA - MinWA) x Shifta]
- BA = Base ATP
- Shifta = Shifta base power in %
- MWA = Maximum possible weapon ATP
- MinWA = Minimum possible weapon ATP
3. Then, determine the minimum and maximum Variance (V):
V(min) = -CV
- CV = Class Variance (5 for Hunter, 3 for Ranger, 2 for Force)
V(max) = MWA - MinWA
- MWA = Maximum possible weapon ATP
- MinWA = Minimum possible weapon ATP
4. To determine your final ATP, add your BA, EA, SA and chosen V together:
ATP = BA + EA + SA + V
5. Finally, to calculate your damage on an enemy:
Damage = [(ATP - Enemy DFP)/5] x Attack modifier
- Attack modifier is:
- Normal: 0.9
- Heavy: 1.89
- Special: 0.56
- Sacrificial: 3.33
Vjaya: 5.67
5a. If the attack is a critical hit, calculate critical damage:
Critical damage = Damage x 1.5
- The chance for an attack to be a critical hit is calculated with the following formula:
Critical hit rate = [LCK/5]%
Note: the game doesn't round up damage values and instead truncates them. E.g. if the final calculated damage is 100.92, the real damage output is 100.
Knockdown
Characters will be knocked down if a single attack does more than 25% of their max HP.
Accuracy
To calculate accuracy:
1. Begin by calculating "Effective" ATA:
Effective ATA = (Total ATA) * (Attack Type modifier) * (Combo Step modifier)
- Attack Type modifier is:
- Normal: 1.0
- Heavy: 0.7
- Special: 0.5
- Combo Step modifier is:
- First attack: 1.0
- Second attack: 1.3
- Third attack: 1.69
2. Next, calculate the enemy's "Effective" EVP:
Effective EVP = (Enemy EVP) * (Status Effect modifier)
3. Finally, calculate accuracy using the appropriate melee or ranged accuracy formula:
Melee Attack Accuracy = (Effective ATA) - ((Effective EVP) * 0.2)
Ranged Attack Accuracy = (Effective ATA) - ((Effective EVP) * 0.2) - (Distance Penalty)
- The calculated numbers are percentages. For accuracy values above
100, the given attack hits 100%. For negative values, the attack always misses (0%). - Distance Penalty is
Distance * 0.33if the character is a Hunter or Force without
Smartlink (see Smartlink page for more detail), and 0 otherwise.
The accuracy check does not occur for certain projectiles if the target has moved too far when the projectile reaches the target's hitbox. This distance is 8 units for bullets. If the target has moved towards the player when manual evasion occurs, the "MISS" text is displayed. Certain weapons create attacks with launcher projectiles that do not have a manual evasion check.
Slicer projectiles follow different rules for collision. The projectile must come within 10 units of its intended target's original position for any collision check to occur. When this condition is met, the projectile connects with the target if the distance between the target's hitbox and the slicer's original position is less than the weapon's max distance. Due to consideration of the target's hitbox, slicers rarely experience manual evasion on most enemies.
Projectiles that are both subject to manual evasion and specifically fired at a target will have a lifetime calculated by (Distance to Target) / Speed. It is possible for the game to destroy the projectile before it physically collides with the target's hitbox if the target was pushed back. There will be no "MISS" text in this case. This is commonly seen when using Heavy Attacks with weapons such as 
L&K38 Combat and Yasminkov 9000M at a distance.
Techniques
Technique damage formula
[(MST + TBP)/5] x (1.0 + CB + WB + FB + MB) x (1 - RES)
- TBP: Technique Base Power
- CB: Class Boost
- WB: Weapon Boost
- FB: Frame Boost
- MB: Merge Boost
- RES: Enemy Resistance
