Damage Calculation

From Empires of the Undergrowth Official Wiki

This page shows damage calculation and related mechanics.


Damage

Attacks are abilities that inflict damage or execution on enemies.

Attack damage is applied immediately while effect damage is applied separately afterward.

Damage must be either physical or venom. Only the male scientist, some titans and environmental hazards can inflict true damage, which ignores all damage modifications.


Area damage

Area attacks will inflict damage on multiple enemies over a certain area at once. The affected area is calculated from the main target.

Splash attacks will inflict less damage on non-targeted enemies if they aren't within a certain radius from the main target. The formula hasn't been revealed.


Damage modifications

  • Area resistance: Creatures with this stat can reduce taken damage from area attacks if they are outside a certain radius from the main target.
  • Armor: Creatures with this stat can reduce taken damage by a flat amount.
  • Physical resistance: Creatures with this stat can reduce taken damage from physical attacks by a certain percentage.
  • Venom resistance: Creatures with this stat can reduce taken damage from venom attacks by a certain percentage.
  • Piercing: Creatures with this stat can reduce physical resistance or venom resistance of enemies in damage calculation.
  • Front resistance: Creatures with this stat can reduce taken damage from frontal attacks by a certain percentage.
  • Maximum taken damage: Creatures with this stat can only take a certain maximum amount of damage from each attack.
  • Evasion: Creatures with this stat have certain chance to evade attacks and skip damage calculation.


Damage formula

Total damage is calculated based on this formula.

Total damage = [base damage x splash percentage x (100% - AOE resistance) - armor] x [(100% - (physical or venom resistance - piercing)]

The value of [resistance - piercing] can't be negative. The value of [damage - armor] must have a minimum value of 0.5.

Resistance modifying effects and maximum taken damage are only applied after total damage has been calculated.

Each instant of damage in damage-over-time effects is treated as an attack of its own.

Examples

The attacker deals 5 physical damage initially. It also deals 10 venom damage every 0.5 second over 2 seconds afterward. The defender has 20% physical resistance and 10% venom resistance.

=> Attack damage = 5 x (1 - 0.2) = 4.

=> Effect damage = 10 x (1 - 0.1) x 2 / 0.5 = 36.

=> Total damage = 4 + 36 = 40.

If the defender can only take maximum of 3 damage per hit, the total damage becomes: 3 + 3 x 2 / 0.5 = 15.
