In the war between the Horde and the Alliance, grudges are taken to the hilt.

Backstab is a hard-hitting move that is performed from behind your enemy. The damage dealt is equal to 1.5 times your normal attack damage plus a flat amount of damage that varies dependent on rank. It only works with a dagger in the main hand.

Notes

Backstab is a great skill for dealing big damage, but you must be behind the mob to use it. It is also good when used in combination with [Seal Fate], as Backstab has a high crit rate when improved via talents.

Limitations

• High energy cost
• You must be behind and facing your target
• Only available when a dagger is equipped in the main hand

Damage calculation formula

The basic Backstab damage formula:

 [Opportunity] = 1 + 0.1 * Opportunity Rank
 [Lethality] = 1 + 0.06 * Lethality Rank
 [Surprise Attacks] = 1 + 0.10 * Surprise Attacks Rank
 [Aggression] = 1 + 0.03 * Aggression Rank
 [Blade Twisting] = 1 + .05 * Blade Twisting Rank
Modifier = Attack Power / 14 * 1.7

Normal hit = ((Weapon Damage + Modifier) * 1.5 + X) * Opportunity * Surprise Attacks * Aggression * Blade Twisting
Critical hit = Normal hit * 2 * Lethality)

So a typical example: lvl 68 combat daggers rogue with a dagger averaging 106 average weapon damage, 1120 attack power, 2 ranks of [Opportunity], the one rank of [Surprise Attacks] and 2 ranks in [Lethality]:

 [Opportunity] = 1.2
 [Lethality] = 1.12
 [Surprise Attacks] = 1.1
 [Aggression] = 1
 [Blade Twisting] = 1
Modifier = 136

Normal Hit = ((106 + 136) * 1.5 + 255) * 1.2 * 1.1 * 1 * 1 = 815.76 average damage
Critical Hit = 815.76 * 2 * 1.12 = 1827.3 average damage

Improvements

• [Puncturing Wounds] increases the critical strike chance of your Backstab by 10/20/30%.
• [Remorseless Attacks] will give your next Backstab a 20/40% increased chance to crit after killing an opponent that yields honor or experience. The improved crit chance lasts for 20 seconds.
• [Opportunity] increases the total damage of your Backstab by 10/20%.
• [Lethality] increases the critical strike damage bonus of your Backstab by 6/12/18/24/30%.
• [Blade Twisting] increases the total damage of your Backstab by 5/10%.
• [Surprise Attacks] increases the total damage of your Backstab by 10%.
• [Aggression] increases the damage of your Backstab ability by 3/6/9/12/15%.
•  [7-30] Dirty Deeds increases the damage of your Backstab ability by 10/20% against targets with less than 35% health
• [Sinister Calling] increases the percentage damage bonus of your Backstab ability by 1/2/3/4/5%.

At full rank of Opportunity, Blade Twisting, Surprise Attacks, Aggression and Sinister Calling, Backstab does 262.9% weapon damage.

Tips and tactics

• When soloing, use [Gouge] to move behind the mob and then Backstab. This earns two combo points off the bat! At higher levels it also combines well with [Cheap Shot] and [Kidney Shot].
• If you want to use the [Gouge]-Backstab combo in the middle of a fight, be sure that your energy is full. Combined they use more energy than you have (unless you have [Vigor]). If you start the combo with less than 100 energy, you'll have to wait to regenerate some more. By that time the effect of [Gouge] will have worn off.
• When grouped, you can get at a mob's back fairly easily. However, if you backstab whenever you can, you are likely to gain aggro, so use with some care. Consider using [Feint] or [Vanish] to keep your Threat level down.
• In PvP, a common method of moving behind another character is to jump forward through them, hold your right mouse button and rotate in mid-air to complete a 180 degree turn. You will land right behind and facing your opponent ready to follow up with a quick backstab!
