Definition

The Damage Score is a synthetic stat in DayZ that measures the overall lethality of a projectile or weapon.
It combines three types of damage applied to the player:

  • Health damage (direct injury)
  • Shock damage (unconsciousness potential)

The score is normalized on a 1–100 scale, where 100 = maximum effect within realistic gameplay ranges.

Formulas:

\(HealthScore = \min\!\Big(\frac{Health}{200},\ 1\Big) \times 100\) \(ShockScore = \min\!\Big(\frac{Shock}{150},\ 1\Big) \times 100\) \(DamageScore = \frac{HealthScore + ShockScore}{2}\)

Where:

  • \(Health\) = base health damage dealt by the projectile
  • \(Shock\) = shock damage dealt by the projectile

Explanation:

  • Each damage type is scaled to a cap (200 for health, 150 for shock/blood).
  • The scaling ensures that extreme values don’t push the score above 100.
  • For the Damage Score, only Health and Shock are averaged, since these two define immediate incapacitation.
  • Blood damage is exposed separately but not included in the final score.

Example:

  • Health = 120 → HealthScore=60HealthScore = 60HealthScore=60
  • Shock = 150 → ShockScore=100ShockScore = 100ShockScore=100

Final Damage Score = (60+100)/2=80(60 + 100) / 2 = 80(60+100)/2=80.
