Base Weapon Damage (BWD): Это каждый урон от оружия, настраиваемый в DefaultGameCore.ini-файл. Диапазоны оружия, показанные в игре в казармах, вычисляются из этого стата на основе процесса рандомизации с алгоритмом, разработанным Amineri для длительной войны.

Modified Weapon Damage (MWD): Это медианный урон после большинства модификаторов, на который применяется процесс рандомизации (+/- 25%). Увеличивается до ММР, таких как Ranger и важный момент таргетинг, повысить общий урон.

Weapon Damage Calculation

Шаги для расчета ущерба:

  1. Roll для шанса на шанс и шанс крита
  2. Применять штраф в BWD из-за навыков
  3. Вычислить модифицированное повреждение оружия (MWD), добавив весь бонусный урон от экипированных предметов и соответствующих льгот
  4. * Добавить бонус критического урона, если критический удар свернут
  5. Рандомизация повреждений: рулон для урона от примерно 75% до 125% от MWD
  6. * Прокатитесь примерно на 125% до 175% от MWD, если критический удар
  7. Применить дальнейшую рандомизацию, а диапазон отпадает для взрывчатых веществ
  8. Вычесть цель DR
  9. Добавить дополнительный бонусный урон от определенных льгот

Accuracy and Critical Chance

Все источники защиты на цели вычитаются из всех источников цели на стрелка, чтобы получить процентный шанс попадания, равный результату сети из 100. Пробой можно просмотреть, используя F1, в то время как таргетинг на врага, который отображает вероятность попадания конкретной атаки.

Критический шанс также вычисляется путем сложения всех источников критической вероятности и вычитания любых критических штрафных очков. Уязвимость Resilience снижает критический шанс до нуля. Реактивный огонь не может критически ударить без эффекта Opportunist или если цель одета в Chameleon Suit.

Охранный огонь получает уникальные мультипликативные штрафы. Они применяются после вычисления вероятности случайного попадания.

Overwatch Penalties

Overwatch fire (not including Suppression) has multiplicative penalties applied to it after normal hit is calculated. All penalties stack multiplicatively with each other.

  • Base Reaction Fire penalty: x0.7, or x0.5 if the target is dashing (removed if the shooter has the Opportunist perk)
  • Lightning Reflexes: x0.1 for the first shot, and x0.3 for each subsequent shot.
  • Chameleon Suit: x0.5

Damage Penalties

Penalties to base damage from special skills are applied here. Because the damage is rounded down to the nearest integer, increasing weapon tech levels to an odd BWD will not increase the damage of special skills. Note that sources of extra damage are not reduced by these special skills, as they apply only to base damage.

Computing Modified Weapon Damage (MWD)

MWD is the sum of BWD and all the flat bonuses to weapon damage from equipped items and relevant perks. If a critical hit was previously rolled, all sources of critical hit damage are added as well, and the average damage is increased by ~50% in the randomization step.

Note that Mayhem Suppression always has an MWD of exactly 2 regardless of other additive modifiers, and no randomization is applied to it.

Sources of MWD

MWD Critical Hit Bonuses

Note: the game adds all sources of critical damage before the ~50% critical hit bonus in the randomization step, but all in-game descriptions of bonus critical damage include the ~50% bonus, so in-game descriptions will be ~50% higher than mentioned here, but the net effect is the same in most cases.

  • Targeting Module [Small Item]: +1
  • Precision Shot [Skill]: +2 for Ballistic, Laser, and Gauss; +3 for Pulse; +4 for Plasma (for Sniper Rifles only)
  • Bring Em On [Perk]: +1 damage for 1-2 visible enemies; +2 damage for 3-4 visible enemies; +3 damage for 5-6 visible enemies; +4 damage for 7 or more visible enemies
  • Killer Instinct [Perk]: +33.4% of BWD, rounded up; ranges from +2 to +4 depending on weapon and tech level, see the chart, below
  • Plasma Rifle [Weappn]: +1 to Biological targets
  • Reflex Cannon [Weapon]: +1 on targets within 4 tiles
  • Reflex Rifle [Weapon]: +1 to flanked or exposed targets
  • Plasma Sniper Rifle [Weapon]: +1 to targets beyond 35 range (~23 tiles)

Damage Randomization

The purpose of the randomization is to pick a integer value between roughly MWD*0.75 and MWD*1.25 with an average of MWD*1.0. For critical hits, the same length interval is used, except shifted to an average of ~MWD*1.5, though critical hits will always at least as much damage as the highest possible roll for a regular hit, and this requirement sometimes increases the average past 1.5*MWD. Damage Roulette changes the range from 0.5*MWD to 1.5*MWD, with the average damage of critical hits increased to MWD*2.0; again, with the same damage range.

The randomization works in integer values only. A die of size 2*MWD+2 is rolled, where each integer point of final damage is assigned up to four possible results on that die (except for the highest and lowest values, which may be assigned less). The weighted average of all possible results equals MWD. For a better understanding, reference the charts, below.

MWD Randomization Table: Regular Hit

LR MWD randomisation noncrit.jpg

Y axis has MWD values. Row values are possible randomisation results for that particular MWD based on the 2*MWD+2 system. The rightmost column has weapon's damage range (min,max) for that MWD. The probability to roll a particular value given a particular MWD is (number of times value appears in the row) / (total number of values in the row).

MWD Randomization Table: Critical Hit

LR MWD randomisation crits.jpg

Y axis has MWD values. Row values are possible randomization results for that particular MWD based on the 2*MWD+2 system. The rightmost column has weapon's damage range (min,max) for that MWD. The probability to roll a particular value given a particular MWD is (number of times value appears in the row) / (total number of values in the row). Note that the average damage is shifted approximately 50% (or more) higher, and the lowest damage roll is always equal to or higher than the largest damage roll in the corresponding row of the regular hit table.

Extra Explosive RNG

Each unit has the damage reduced based on distance from the center. Damage falls as the square of the radius, down to 25% at the edge.

Explosives also have extra RNG associated with them. Each target hit is equally likely to randomly roll +1, 0, or -1 to damage, reflecting a higher damage range than regular weapons.

Damage Reduction

Long War adds a new mechanic called Damage Reduction. When a unit takes damage, the amount is reduced by the damage reduction value. The amount blocked by damage reduction can be seen in game as a blue shield icon below the normal red damage indication text after a shot.

If the damage reduction a unit has is not a whole number, the damage is reduced by one of the two nearest whole numbers, with probability based on the fraction. For example, a unit with 1.66 damage reduction has a 66% chance of the damage being reduced by 2 and a 34% chance of the damage being reduced by 1.

The steps to calculating DR are as follows:

  1. Flat Inherent DR is applied
  2. Acid negates the higher of 50% or 3 points of the above DR.
  3. Percentage DR is applied (multiplicatively) to the remaining damage
  4. Flat Cover DR is applied, if the target is in cover and not flanked, and the weapon is not an AP Grenade or Shredder Rocket
  5. Other effects that negate DR (except acid) are applied
  6. If there is any net DR from the above steps, it is multiplied by 1.5 if damage source is a shotgun without breaching ammo

Sources of DR

Flat Inherent DR

From Armor:

Other Sources:

Note: each Ethereal still alive in the final Temple Ship room adds 15 bonus DR to the Uber Ethereal.

Percentage DR

Damage in excess of inherent DR has the following stacking multipliers applied to it. For instance, a Mectoid with Psi Shield and Shock-Absorbent Armor who is attacked from close range reduces the resulting damage to to 0.5*0.667 = 0.3335 of it's normal value, so a shot that rolled 21 damage deals 21*0.3335 = 7 damage, with 14 blocked by DR.

Flat Cover DR

Applies only if the target is in cover and not flanked, and the weapon is not an AP Grenade or Shredder Rocket.

Flat DR Reduction

DR reduction cannot exceed the targets DR; that is, any DR reduction beyond that amount is ignored. Note that acid is in it's own separate category; reference the steps to calculating DR above.

Bonus Damage

Some sources of bonus damage are applied after all other steps, including MWD, randomization, and DR.

  • Shredder Ammo: If the target is shredded, the remaining damage after DR (if any) is multiplied by 1.4 rounded down, with a minimum increase of 1. Shredding can be completely negated by DR, but if the resulting damage after DR is non-zero, Shredding will always add at least 1 extra point of damage. The shredder bonus does not apply to any extra damage from the other bonus sources in this list.
  • HEAT Ammo & HEAT Warheads: If the target is robotic, HEAT adds a bonus of 0.5*BWD rounded down. Note that it adds Base Weapon Damage. Even if the attack was reduced to zero damage through DR, HEAT will still inflict it's full damage. Reference the charts below for a detailed breakdown on the bonus damage for each weapon type.
  • Flak Ammo: If the target is flying, Flak Ammo adds a bonus of 0.2*BWD rounded up, or 2, whichever is higher. This is functionally similar to HEAT ammo. Most weapons gain a bonus of 2 from Flak Ammo; weapons with base damage of between 11 and 15 gain 3.
