Critical hit

Critical hit.

A critical hit, also known as a critical strike, critical, or crit, is a mechanic that multiplies the direct damage of an attack. The chance of a critical hit is determined by the precision attribute and any bonuses to critical chance such as from fury or from certain skills and traits. Critical hits deal 150% damage by default, and this multiplier, known as critical damage, can be increased by the ferocity attribute. Some effects trigger specifically after a critical strike, including some from traits, sigils, or runes as listed below. Critical hit damage is displayed in larger text than ordinary damage and is highlighted with a red splash.

Only direct damage, not Condition Damage, can be a critical hit.

Formula

The expected average damage output is determined by the following formula:

Average damage = Base damage * ( 1 - Critical Chance ) + Base damage * ( Critical Chance * Critical Damage )

Re-factored, this simplifies to:

Average damage = Base damage * ( 1 + Critical Chance * ( Critical Damage - 1 ) )

Example: given a critical chance of 25% and critical damage of 180%, average damage output is 20% greater than normal.

Average damage = base * ( 1 + 0.25 * ( 1.8 - 1 ) ) 
               = base * ( 1 + 0.25 * 0.8 )
               = base * 1.2

Average damage increase

The table below shows the average increase in damage from critical hits based on the chance to hit critically (rows) and the bonus Critical Damage from that attribute (columns). For example: if your critical chance is 20% and your critical damage is 155%, the 1.110 means that, over time, you will end up doing 11% more damage than if both attributes were zero.

Player chatter

When a character hits a foe with a critical hit, they will occasionally shout out one of the following lines, depending on their race and gender.

Race	Gender
	Male	Female
Asura	I've beaten you, but you don't know it yet. For the record: you've been struck!	How does that feel? Excruciating? Maximum pain! I've got a lesson to teach you.
Charr	Oh, that had to hurt.	Feel the pain! Did that hurt?
Human	There's one to remember me by. Oh, that had to hurt.	Hurts, doesn't it? You'll be feeling that one for days. BAM!
Norn	HAH! Extra damage!
Sylvari	Take that!	Give up yet?

Anomaly:

Characters will sometimes shout upon receiving a critical hit from an enemy.

Notes

• As stated above, Condition Damage cannot critically strike.
  • Consequently, condition damage gains no benefit from precision or critical damage modifiers.
• A character's chance of critical cannot become higher than 100%.
