## Basic Formulas Edit

Before we get too worried about the Sinister Strike formula, it is important to understand the basic damage formula.

- All of the following formula will have to be done twice, using minimum weapon damage once, and maximum weapon damage in order to determine the damage range. Alternatively you could use the average between the two to determine your average Sinister Strike damage.

### White Attack Edit

This is the basic "White Attack" formula, which is the basis for the Sinister Strike formula.

(Attack Power / 14) * Weapon Speed + Weapon Damage = Damage

(Comment: I think it should be (Attack Power / 14) / Weapon Speed + Weapon Damage = Damage )

### Sinister Strike Edit

The formula will be shown using Sinister Strike Rank 10.

You'll notice that the "Weapon Speed" is substituted by "Normalized Weapon Speed" because we're dealing with an instant attack.

Normalized weapon speeds are as follows.

- Dagger: 1.7
- 1H Melee: 2.4
- 2H Melee: 3.3

*In most cases, you'll be dealing with a 1H melee weapon.*

#### Normal Hit Edit

(Attack Power / 14) * Normalized Weapon Speed + Weapon Damage+ 98= Damage

*Notice the +98 damage added by Sinister Strike.*

## Advanced Formulas Edit

We mustn't forget that there are three Rogue talents that affect the amount of damage done by Sinister Strike.

### Lethality Edit

With the full 5 talent points, Lethality "Increases the critical strike damage bonus of your Sinister Strike, Gouge, Backstab, Ghostly Strike, Mutilate, Shiv and Hemorrhage ability by 30%."

[(Attack Power / 14) * Normalized Weapon Speed + Weapon Damage + 98] * 2.3= Damage

*The critical hit multiplier gains the additional 30%(.3 in decimal) bonus from lethality.*

### Aggression Edit

With the full 3 talent points, Aggression "Increases the damage of your Sinister Strike and Eviscerate abilities by 6%."

#### Normal Hit Edit

[(Attack Power / 14) * Normalized Weapon Speed + Weapon Damage + 98]* 1.06= Damage

*The Sinister Strike damage is now multiplied by 106%(1.06 in decimal) to add in the bonus from Aggression.*

### Surprise Attacks Edit

Surprise Attacks "Your finishing moves can no longer be dodged, and the damage dealt by your Sinister Strike, Backstab, Shiv and Gouge abilities is increased by 10%."

#### Normal Hit Edit

[(Attack Power / 14) * Normalized Weapon Speed + Weapon Damage + 98] *1.1= Damage

*The Sinister Strike damage is now multiplied by 110%(1.1 in decimal) to add in the bonus from Surprise Attacks.*

### Lethality, Aggression & Surprise Attacks Edit

[([(Attack Power / 14) * Normalized Weapon Speed + Weapon Damage + 98] * 1.06) * 1.1] * 2.3 = Damage

*It is important to remember that Blizzard "stacks" their percentages, instead of simply adding them to each other.*
