Talent improvement

• [Remorseless Attacks] will give your next Hemorrhage a 20% or 40% increased chance to crit after killing an opponent that yields honor or experience. The improved crit chance lasts for 20 seconds.
• [Lethality] increases the critical strike damage bonus of your Hemorrhage by 6%, 12%, 18%, 24%, or 30%.
• [Sinister Calling] now increases the percentage damage bonus of Hemorrhage by 2/4/6/8/10%

Item improvement

• The 4 piece bonus of the Bonescythe Armor Set gives you 5 Energy for every one of your Hemorrhage critical hits.
• The 6 piece bonus of the Bonescythe Armor Set reduces the threat generated from your Hemorrhage by 8%.
• The 4 piece bonus of the Slayer's Armor Set increases the damage done by Hemorrhage by 6%.

Damage calculation formula

The basic formula for calculating hemorrhage damage is:

 [Lethality] = (0.06 * Lethality Rank)
Critical Factor = 2 + Lethality

Normal Hemorrhage Damage = [(Attack Power/14 * 2.4) + Weapon Damage]*1.10 (no Sinister Calling)
or
Normal Hemorrhage Damage = [(Attack Power/14 * 2.4) + Weapon Damage]*1.20 (with Sinister Calling)
Critical Hemorrhage Damage = Normal Hemorrhage Damage * Critical Factor

Note that the bonus from Sinister Calling is additive!

Thinking of speccing Hemorrhage?

• Hemorrhage does not stack with [Garrote] nor [Rupture] as it is not a bleed effect; the additional damage is not applied to the DPS of either ability.
• [Seal Fate] is wasted on a hemorrhage build, as +9% agility and a full +10% attack power is better, until a 30% or higher crit rate is achieved. If you play PvP consider that the average opponent will have around ~400 resilience, so ~10% critical hit chance reduction; you will need around 40% or higher crit rate to efficiently use Seal Fate with hemo. On pre-TBC this options was viable since resilience was not present in the game and was easy to reach 30% crit chance, but even then it was a poor choice in comparison to the standard hemo build as Seal Fate only performed well with daggers with Imp BS and Imp Ambush.
• If you plan to use Hemorrhage always look for the weapon that has acceptable DPS with the highest average damage that you can obtain. If you are making a choice, choose the weapon with the best average damage.
• For PvE, you do not spec Hemorrhage to top damagemeters, especially not when compared to "normal", i.e. Combat-Sword rogues. Expect your personal DPS on the meters to be lower. You are sacrificing personal DPS to improve overal raid DPS.

Past changes

• In Patch 2.3, initial damage was increased to 125% of weapon damage from 100%, but was normalized.
• In Patch 2.3.2, 125% of weapon damage was changed to 110% and the damage done per physical strike in the debuff increased from 36 to 42.
