%{font-size:16pt}*+Damage Calculation Formula and Multipliers+*%
(Posted here in hopes of more contribution and for lack of a better subforum to put it in)

%{font-size:14pt}*Intro*%
The following is the current damage calculation formula as well as listings of items that affect the damage. Much of these numbers have been determined experimentally. Only the results are listed here but if you wish to see any specific test numbers, I can post them here as well. These are based off what is currently available in the Mist. The values in %{color:red}*red*% have not been tested yet, most likely due to difficulty in testing (i.e. requires an attacking dummy).

%{font-size:14pt}*Formula*%
Dmg = Weapon * Skill Mult * Power * Crit Mult * Compound Mult / Target Armour
* Weapon = Weapon damage value, see weapon stats
* Skill Mult = Skill multiplier, determined experimentally
* Power = Power stat, see character stats
* Crit Mult = Crit multiplier, increased by gear bonus and traits
* Compound Mult = Various other multipliers applied separately
* Target Armour = Target's armour value

%{font-size:14pt}*Power*%
The power stat is increased through gear bonuses, trait bonuses, and buffs. It is a flat, additively incremented value that is multiplied with the weapon damage value before being further multiplied by other multipliers.
* 916 base power
* +35 per stack of _Might_ buff
* +10 per stack of _Bloodlust_ buff from _Sigil of Superior Bloodlust_ weapon sigil, 2 stacks per enemy kill - max +250 (25 stacks)
* +25 (1 Might) _Sigil of Superior Strength_ weapon sigil
* +105 (3 Might) _Sigil of Superior Battle_ weapon sigil

*Warrior-specific:*
* +10 per _Strength_ trait point - max +300 (30 trait points)
* +35 (1 Might) _Signet of Might_ (passive) utility skill (signet)
* +175 (5 Might) _Signet of Might_ (active) utility skill (signet)
* +175 (5 Might) _Signet of Rage_ utility skill (signet)
* +35 (1 Might) _I Will Avenge You!_ utility skill (shout)
* +105 (3 Might) _For Great Justice!_ utility skill (shout)
* +45 _Banner of Strength_ utility skill (banner)
* +105 (3 Might) _Battle Standard_ elite skill (banner)
* +105 (3 Might) _Flex_ trait on Physical utility skill usage
* + 35 (1 Might) _Momentous Greatsword_ trait on greatsword crit
* + %{color:red}*???*% ( %{color:red}*???*% Might) _Short Temper_ trait on Block by enemy
* + %{color:red}*???*% ( %{color:red}*???*% Might) _Mighty Defences_ trait on Block of enemy attack
* + %{color:red}*???*% ( %{color:red}*???*% Might) to nearby allies from _Reviver's Might_ trait on reviving an ally
* + %{color:red}*???*% to nearby allies from _Empower Allies_ trait


%{font-size:14pt}*Crit Multipliers*%
Crit multipliers are combined additively. It is only multiplied in upon a critical hit.
* +50% base crit multiplier
* +31% _Amulet PvP Pow Pre CritDmg_ accessory
* +3% _Perfect Ruby Jewel_ accessory jewel - max +15% (5 accessories)
* +X% _Superior Rune of the Eagle/ Golemancer/ Ogre/ Rage/ Wurm/ Ranger/ Scholar_ armour runes - any of +2/3/4/5%

*Warrior-specific:*
* +1% per _Discipline_ trait point - max +30% (30 trait points)
* +10% _Axe Mastery_ trait if wielding axe
* +9% _Banner of Discipline_ utility skill (banner)
* +35% _Frenzy_ buff (_Frenzy_ utility skill and _Last Chance_ trait if target is <25% HP)


%{font-size:14pt}*Compound Multipliers*%
These multipliers combine multiplicatively. The more multipliers stacked together, the greater the influence each compound multiplier has.
* +5% _Sigil of Superior Force_ weapon sigil
* +30% _Doom_ buff from _Sigil of Superior Doom_ weapon sigil on weapon swap

*Warrior-specific:*
* +0.1% per _Discipline_ trait point for Burst skills - max +3% (30 trait points)
* +3% _Stick and Move_ trait if Endurance bar not full
* +5% _Weapon Specialization_ trait if wielding axe, mace or sword in off-hand
* +10% _Attack of Opportunity_ trait if target is bleeding
* +5% _Cull the Weak_ trait if target is weakened
* +10% _Burning Arrows_ trait if wielding longbow against burning enemy
* + %{color:red}*???*%% _Desperate Power_ trait when <25% HP
* + %{color:red}*???*%% _Empowered_ trait per boon


%{font-size:14pt}*Target Armour*%
This part I have not experimented much with. There are too many different skills/traits that can apply the Vulnerability condition so I won't list them.
* 2600 _Target Golem – Heavy_ test dummy NPC
* 2300 _Target Golem – Medium_ test dummy NPC
* 1900 _Target Golem – Light_ test dummy NPC
* -50 per Vulnerability condition stack


%{font-size:14pt}*Skill Multiplier*%
These are the rounded values determined experimentally with Steady weapons in the Mist. Confirmations by devs would be greatly appreciated ^_^

%{font-size:14pt}*Please Contribute!*%
There are probably other in-game items that give multipliers in addition to those listed here. If you know any, please test them thoroughly and post here (this is FAR from a comprehensive list). As well, if you know of any inaccuracies and have the test data to prove it, please post here as well. These tests were also done on a Warrior so I have not included multiplier from traits of other classes - please also post here if you know them so I can add on to this list.
