I wanted to make a thread about the mathematics of Warrior bleeds as I was unsure about the exact way certain things were stacking and I wanted some community input. Furthermore, I want to give some indication of how powerful bleeds are. Please note that the gear choices made in this thread have been made to illustrate the maximum damage of a single bleed or bleed skill. The build is not meant to be competitive or realistic.

Regarding Malice, Guild Wars 2 Wiki states that bleeds are separated in to one second ticks, and that 20 Malice adds one damage per tick. Source: Guild Wars 2 Wiki. Additionally, I would also like to note that bleeds can only stack up to 25, with long duration bleeds it might be possible to hit this maximum.

**Runes, Sigils, Jewellery and Traits**

**Total Malice:**1507.

**Malice damage per bleed tick:**1507 / 20 = 75.35

**Condition/bleed duration increases:**50%, 30%, 15%, 15%, 10% and 10%. Additive total: 130%.

**Sources of duration increases:**

- Deep Cuts (Arms major trait), increases bleed duration by 50%.
- Expertise from the Strength tree, increases condition duration by 30%.
- Rune of the Afflicted (3 of these), increases bleed duration by 15%.
- Rune of the Krait (3 of these), increases bleed duration by 15%.
- Sigil of Superior Agony, increases bleed duration by 10%.

**The Sever Artery example**

Sever Artery, a sword chain attack that does 360 bleed damage over 8 seconds. Source: GW2tools.

**Step 1: Calculate the maximum duration**

50% + 30% + 15% + 15% + 10% + 10% = 130% duration increase

8 seconds * 2.30 (130%) = 18.4 seconds, 18 seconds rounded down

**Step 2: Calculate the base damage per tick**

360 damage / 8 seconds = 45 damage per tick (one tick per second)

**Step 3: Calculate the extra damage from Malice per tick**

1507 Malice / 20 (Malice needed for one damage per tick) = 75.35 damage per tick

**Step 4: Add the damage from Malice and the base damage together (per tick)**

45 damage per tick + 75.35 damage per tick = 120.35 damage per tick, 120 rounded down

**Step 5: Multiply the total damage per tick by the duration (i.e. number of ticks)**

120 damage per tick * 18 ticks (one per second) = 2160 damage over 18 seconds

**Summary:**

**With**

*near*maximum Malice and bleed duration the bleed component of a single Sever Artery will do 2160 damage over 18 seconds. DPS: 120.**The (quicker) Impale and Riposte example**

Impale and Riposte, the off hand sword skills that do 2160 damage over 12 seconds. They each apply four bleeds. Source: Guild Wars 2 Tools.

1: 50% + 30% + 15% + 15% + 10% + 10% = 130%

12 * 2.30 = 27.6, round down to 27

2: (2160 / 4) / 12 = 45 // 4 bleeds remember

3: 1507 / 20 = 75.35

4: 75.35 + 45 = 120.35, round down to 120

5: 120 * 27 = 3240

6: 3240 * 4 = 12960 // remember there are four bleeds (extra step)

**Summary: With**

*near*maximum Malice and bleed duration the bleed components of Impale and Riposte will do 12960 damage over 27 seconds. DPS: 480.**Something to note**

At this point I'd like to note that the base damage of bleeds always seems to be 45 (credit goes to IOUmoney here). I find this relevant for two reasons:

- You can calculate an items/Traits default damage without it being listed. For example, Sigil of Superior Earth does 225 damage (45 damage * 5 second duration) by default.
- Bleed damage can be calculated quickly using: ((Malice / 20) + 45 ) * round(base duration * sum of duration increases).
- If you need to calculate the damage of many bleeds, the first bracket is always constant; therefore, if you have worked out X = ((Malice / 20) + 45) you can just calculate the damage like this: X * round(base duration * sum of duration increases) for each bleed.

**Questions and Answers**

**Answered Questions**

**Question:**Does bleed duration stack additively or multiplicatively?

**Tentative answer:**Boons appear to be stacking additively, therefore, conditions probably do to. Needs more confirmation. Source.**Question:**Does increasing the duration of the bleed also increase the damage it does (proportionately)?

**Answer**: "Yes, bleeds are divided into one second ticks. Each tick has a base value, modified by Malice." Source: Mammoth's post on page one.**Question:**Is Malice applied before or after a duration increase?

**Answer**: Malice is applied to each tick of a bleed. The duration of the bleed is irrelevant. Source: Mammoth's post on the first page of this thread.**Question:**Does the Malice modifier apply to every bleed that Impale applies?

**Answer:**Yes it does. Source: IOUmoney's post on page one of this thread.

**Unanswered Questions**

**Question:**Does Sigil of Superior Agony affect bleeds on both weapons?

**Assumption in calculations:**Yes.**Question:**How does damage rounding work in GW2?

**Assumption in calculations:**Always round down.**Question:**Do bleeds have a maximum duration?

**Assumption in calculations:**No.
