For the end formula, see the Hitpoints Damage section

For a simplified formula, see the Damage伤害 section in Combat Mechanics

The game calculates damage in two steps. First the damage dealt by the skill used. Then the damage received by the target. For the sake of clarity this article is divided accordingly. This is a definition of the terms used in some of the formulas:

rand(x,y) = a random number between x and y
min(x,y) = the minimum between x and y
max(x,y) = the maximum between x and y

Each variable has a default value that can be modified by one or several modifiers. The value can be multiplied (*), added (+), subtracted (-) or a new value can be set (=). This page lists all usable skills in the game.

Direct Damage

The result is a multiplier not an amount of damage.

Direct Damage Multiplier

See Weapons for default values. Some skills and perks can modify the weapon value.

It seems that direct damage is solely determined by weapon skills. Direct damage modifiers within weapon files are used solely for UI purposes. This means that for example a Goedendag will ignore 25% of armor when using Thrust and 40% when using Knock-Out, although the weapon descriptions states it as ignoring 25% of armor. Possibly, this used to be different.

Direct Damage Addend

Fatigue Damage

Minimum Damage

Secondary Damage

Secondary damage ignores armor (unless it specifically targets it like acid). It stacks if applied multiple times. As damage from attacks it can be resisted (see the Damage Received承受伤害 section) but Nimble does not protect against it. All effects are removed after combat.

Damage over Time

Bleeding流血

Bleeding is caused by Cleavers Cleave Skill, Jagged Pike锯齿长枪 Rupture Skill and Whips Whip Skill for 5 damage (2 stacks of Bleed for Whips) over 2 turns (3 with the Bleeder Trait). The damage is increased to 10 for Cleave and Whip Skills with the Cleaver Mastery. The minimum (hitpoints) damage necessary for the effect to occur at all is 6.

Some 一些Temporary Injuries cause bleeding like damage for the duration of the battle when they were sustained. Grazed Neck deals 1 damage per turn and Cut Artery deals 3. Both these Injuries as well as any bleeding can be cured with Bandages绷带 First Aid Skill. Undead are immune to bleeding.

Poison毒素

Poison is used by Goblin Ambushers and Webknechts. But only Webknechts poison inflicts damage. Like bleeding, poison is only applied if 7 or more (hitpoints) damage has been dealt. The spider poison deals 5 damage per turn for 3 turns (4 with the Ailing Trait). Poisoned Oil淬毒油 works a bit differently. Webknechts, Undead and some other monsters are immune to the effect.

Acid

Acid is sprayed over armor when hitting an adjacent Lindwurm for more than 10 damage or by being hit with an Acid Flask酸液瓶. The acidic effect lasts 3 turns and removes 10% of current body (20% with the flask) and head armor (4% with the flask) durability. Lindwurms are immune to the effect. A body armor with the Lindwurm Scale Cloak Armor Attachment is unaffected by it. The Lindwurm Armor and Lindwurm Helmet are also unaffected.

Blessed Water

See Flask of Blessed Water圣水瓶.

Miscellaneous

Falling Damage

This occurs when being pushed down from a height by skills that repel or knock targets back. The damage equals 10 per level difference.

Hex咒缚

The damage taken by the caster of the hex is mirrored.

Nightmare梦魇

This skill is used by Alps follows a special formula for damage.

Examples

Case 1

Actors, Skills & Equipment

Sigurd the Beast attacks a Brigand Raider.

Sigurd uses the following skills, perks, traits:

• Huge高大
• Overhead Strike (common Greatsword)
• Killing Frenzy杀戮狂热
• Brute蛮力

Our guinea pig is a poor Brigand Raider with the following equipment:

• Ragged surcoat (55 durability)
• Headscarf (20 durability)

Damage伤害

Sigurd attacks the Raider with Overhead Strike and hits the head!

body damage multiplier = 1.5 + 0.15 = 1.65 (no Steel Brow)

Overhead Strike has + 20 regular damage!

regular damage range is 105 - 125

Sigurd rolls 125 on regular damage! He is Huge and is under a Killing Frenzy!

regular damage = 125 * 1.1 * 1.25 = 171

Sigurd rolls 105 on armor damage!

armor damage = 105 * 1.1 * 1.25 = 144

The headscarf is utterly destroyed!

damage = 171 * 0.25 (direct damage) + 171 * (1 - 0.25) - 20 (armor damage) = 151

It's a critical hit!

damage = 151 * 1.65 = 249

Our puny Raider only has 75 hitpoints! His head flies in the air and Sigurd the Beast gleefully adds it to his collection!

Case 2

Actors, Skills & Equipment

Olaf the Reckless has put himself in deep trouble as usual and is attacked by an Orc Young.

Olaf has 60 hitpoints left of 100 and has the following equipment and skills:

• Reinforced Mail Hauberk (210 durability) with Additional Fur Padding
• Indomitable不屈
• Battle Forged久经战阵

The Orc Young uses the following skills:

• Decapitate (Head Chopper)
• Double Grip双手握持

Damage伤害

The Orc Young hits Olaf's body with Decapitate!

body damage multiplier = 1

Head Chopper has a range of 40 - 70 and the Orc Young rolls 60 on regular damage! He uses Decapitate, has Double Grip and a racial bonus!

regular damage dealt = 60 * (1 + 1 - 60/100) * 1.25 * 1.15 = 120

The Orc Young rolls 70 on armor damage!

armor damage dealt = 70 * 1.1 * 1.25 * 1.15 = 110

Olaf is under Indomitable!

regular damage received = 120 * 0.5 = 60

Olaf also has Battle Forged!

armor damage received = 110 * 0.5 * (1 - 210 * 0.05 * 0.01) = 49

Olaf's Reinforced Mail Hauberk is left with 161 durability! Olaf's armor has Additional Fur Padding!

damage = 60 * 0.25 (direct damage) * 0.66 - 161 * 0.1 = 0 (−6.2)

Olaf the Reckless makes it this time! Hopefully he'll eventually learn the meaning of his surname!

Case 3

Actors, Skills & Equipment

Gebhard attacks a Size 1 Ifrit.

Gebhard uses the following skill:

• Split Man (Man Splitter)

The Ifrit is a regular small ifrit:

• It has 110 hitpoints
• It has natural armor on body and head (110 durability)
• Being an ifrit, it has no head, and all attacks always hit its body

Damage伤害

Gebhard hits the Ifrit's body with Split Man!

body damage multiplier = 1

Man Splitter has a range of 90 - 120 and Gebhard rolls 120 on regular damage!

regular damage dealt = 120

Gebhard rolls 110 on armor damage! Man Splitter deals 160% damage to armor!

armor damage dealt = 110 * 1.6 = 176

The Ifrit's natural armor is hit for 176 damage and is destroyed! But the armor's durability was 110 which is less, and it is the actual taken damage. The Ifrit takes direct damage! Man Splitter deals 40% damage through armor!

direct damage = 120 * 0.4 = 48

Since the armor is zero, the game calculates additional damage!

additional damage = 120 (regular damage (dealt) * (1 - 0.4 (direct damage)) - 110 (armor damage (taken)) = -38

The game does not decrease damage when the number is negative, so the Ifrit takes 48 damage to hitpoints. Split Man deals a second damage instance with separate rolls! This attack would normally hit the head, but ifrits have none, and it hits its armorless body instead! Body part damage modifier of the second attack of Split Man is always set to 1, even when it hits the head.

body damage multiplier = 1

Gebhard rolls 120 on regular damage again! However its damage is halved.

regular damage dealt = 120 * 0.5

Since there is no armor, armor damage roll does not matter and will not affect anything. The Ifrit takes direct damage!

direct damage = 60 * 0.4 = 24

Since the armor is zero, the game calculates additional damage!

additional damage = 60 (regular damage (dealt) * (1 - 0.4 (direct damage)) - 0 (armor damage (taken)) = 36

Ifrit takes 60 damage from the second part of the attack, and total 108 damage from it. It survives with 2 hitpoints and will probably merge again.
