Weapon skill

Damage = W * P * SC / A
A = T + D

where W is the average value for the weapon strength, P is the power attribute of the player, SC is the coefficient of the current skill, and A is the armor attribute

Power

Power is the primary attribute for calculating how much damage is dealt. Power can be increased through equipment, the might boon, traits, and various effects that provide bonuses to power, such as consumables.

Weapon strength

Weapon strength is the average value of the damage range for a weapon. The weapon range is a uniformly distributed range of possible values with a single value being chosen at random. For one-handed weapons, the damage inflicted is calculated based on the weapon strength of weapon corresponding with the weapon slot. Main hand weapon slots inflict damage based on the weapon strength of the main hand weapon, off-hand weapons slots inflict damage based on the weapon strength of the off-hand weapon.

Weapon	Damage range	Weapon strength
Main hand
Axe	857-1048	952.5
Dagger	924-981	952.5
Mace	895-1,010	952.5
Pistol	876–1,029	952.5
Scepter	895–1,010	952.5
Sword	905–1,000	952.5
Off-hand
Focus	832–883	857.5
Shield	806–909	857.5
Torch	789–926	857.5
Warhorn	814–900	857
Two-handed
Greatsword	995–1,100	1047.5
Hammer	985–1,111	1048
Longbow	920-1080	1000
Rifle	986-1,205	1095.5
Shortbow	905–1,000	952.5
Staff	985–1,111	1048
Aquatic
Harpoon gun	905–1,000	952.5
Spear	905–1,000	952.5
Trident	905–1,000	952.5

Armor

Defense is calculated as the some have the toughness attribute and the defense value. The defense rating is the sum of all the defense values provided by equipment. Utility slots do not provide defense, although they can provide a bonus to toughness. The profession determines whether the player can where heavy, medium, or light armor, where heavy armor provides the most defense and light armor provides the least defense.

Armor piece	Light	Medium	Heavy
Helmet	73	97	121
Shoulders	73	97	121
Chest	314	338	363
Gauntlets	133	157	182
Leggings	194	218	242
Boots	133	157	182
Total	920	1064	1211

This translates to light armor professions taking 33% more damage than heavy armor professions, assuming toughness is constant.

Other sources

All other sources of damage scale linearly with power, except for burst skills as they are intertwined with the weapon itself. Due to this, the skill damage in the tooltip for burst skills is incorrect. These sources include:

• Utility skills
• Elite skills
• Profession mechanics

Utility skills

Damage = P * SC / A

Utility skills tend to deal less damage since weapon strength isn't added to the equation and the skill coefficient doesn't compensate. For example, Bull's Charge will inflict 390 damage while Whirlwind Attack inflicts 553. This is done on purpose to dissuade players from using utility skills as damage and instead to augment damage being done by weapons.

Elite skills

Elite skills don't deal damage directly, instead they use summons, transforms, environmental weapons, and similar. These often simply scale with level, dealing a fixed amount of damage at level 80. Transforms tend to double or triple base stats, as with Rampage, to deal the additional damage. Dagger Storm, Tornado, and Whirlpool deal direct damage and have low skill coefficients to make up for the loss of weapon strength.

Environmental weapons

Environmental weapons have their own weapon strength and provide no innate bonuses to attributes. In general, environmental weapons are less powerful than weapons that can be obtained at the same level. Elementalist conjure weapons scale with level closely with weapons of equivalent level. It's important to note that players will still benefit from any bonuses, including power, from equipped weapons while holding an environmental weapon. At level 80, conjure weapons have a weapon damage of 969, slightly higher than the level 80 dagger in the example. You may note that all main hand weapons have the same weapon damage value. Conjure Flame Axe (+180) and Conjure Fiery Greatsword (+260) give conjure effects that provide a bonus to power, putting them in line with an axe and greatsword respectively.

We can compare the axe and greatsword more rigorously since they scale with power. Lightning Hammer provides bonuses to critical damage, making it slightly more problematic. The max value for power provided by a 2-handed weapon is 179 and for two 1-handed weapons is 180, we will use these values in the calculation and assume we have a power attribute of 2200. Armor and skill coefficient are constant so can be ignored for this comparison.

Greatsword       = 1047.5 * 2999    = 3141452.5 (lol)
Fiery Greatsword = 969 * (2999+260) = 3157971

Axe              = 952.5 * 3000     = 3142500
Lava Axe         = 969 * (3000+180) = 3081420

As you can see, the greatsword is about equal and the lava axe is slightly lower.

Condition damage

Condition damage inflicts a static amount of damage. In this case, static means damage multipliers do not affect the amount of damage dealt by condition damage. All skills, traits, and effects that modify condition damage will increase the Condition Damage attribute rather than provide a percent increase.

Condition	Stacking	Formula
Bleeding	Intensity	0.05 * Condition Damage + 0.5 * Level + 2.5
Burning	Duration	0.25 * Condition Damage + 4.0 * Level + 8
Poison	Duration	0.10 * Condition Damage + 1.0 * Level + 4
Confusion	Intensity	0.15 * Condition Damage + 1.5 * Level + 10

Damage calculation

The formula for damage inflicted on a target can be generalized to damage modifiers that increase the amount of damage inflicted or decrease the amount of damage received.

Damage = (Skill damage * Positive multipliers) / (Armor * Negative multipliers)

Positive multiplier

• Critical hit: 150% + 1% for each point in Critical Damage
• Vulnerability: +1% per stack of vulnerability, up to 25% total
• Sigil of Force: +5% damage
• Sigil of Slaying: +10% against specific family
• Potion of Slaying: +10% against specific family

Negative multiplier

• Glancing blow: -50% from weakness, 50% chance of triggering
• Protection: -33% damage
• Potion of Slaying: -10% against specific family
