Damage Calculations

Damage Formula

[math]\displaystyle{ \text{Damage} = \left [ \left [ \left [ \text{Atk}_\text{cap} \times \text{Mod}_\text{post}\right]\times \text{Crit}\right]-\text{Armour}\right]\times \text{Ammo} }[/math]

  • [math]\displaystyle{ \text{Atk}_\text{cap} }[/math] is the Cap Adjusted Attack Power
  • [math]\displaystyle{ \text{Mod}_\text{post} }[/math] is any post-cap modifiers that are applicable.
  • [math]\displaystyle{ \text{Crit} }[/math] is the critical strike modifier.
  • [math]\displaystyle{ \text{Ammo} }[/math] is the remaining ammunition modifier.
  • [math]\displaystyle{ \text{Armour} }[/math] is the armour of the target.

Where, Cap Adjusted Attack Power is Basic Attack Power that has been adjusted by applying the damage cap.

[math]\displaystyle{ \text{Atk}_\text{cap} = \text{Cap} + \sqrt{\left [ \text{Atk}_\text{basic} \times \text{Mod}_\text{pre}\right]-\text{Cap}} }[/math]

  • [math]\displaystyle{ \text{Cap} }[/math] is the damage cap relevant to the phase.
  • [math]\displaystyle{ \text{Atk}_\text{basic} }[/math] is the basic attack power of the relevant attack.
  • [math]\displaystyle{ \text{Mod}_\text{pre} }[/math] is any pre-cap modifiers that are applicable.

Important Notes

  • Pre- and post-cap multipliers are multiplicative.
  • Results are rounded down to the nearest whole number. I.e. 4.2 → 4.
