How Impairment Works
The follow guide will answer some but not all questions about impairment. The following questions are:
- Does impairment depend on damage or just the level the skill says it is?
- Do back attacks increase the impairment effect?
- How is impairment scaled on their levels?
- How does impairment work with skills with multiple ticks?
1. How Impairment Relates to Damage (It Doesn't) and Impairment Level
- So let's take a look at this DH rifle skill. In the ENG patch its called Great Disaster. In LATree it's Catastrophe.
- As you can see, its default impairment level is II (2) without tripods.
- The following videos show the comparison of a DH using the rifle skill.
- In the 1st video, the DH is using a trash weapon and has a DEX of 638. The skill is rank 1.
- In the 2nd video, the DH has all his armor on and has a DEX of 2108. The skill is rank 10.
- The difference in HP values for the bosses is because the boss scales to the ilvl of the player.
- If you couldn't quite clearly catch it, here are snapshots of the impairment bar.
- Conclusion: Damage is not related to impairment, clearly shown with the difference in ilvls.
2. Do Back Attacks Increase Impairment Effect?
- The DH skill being used for this is called Omen of Apocalypse, a shotgun skill with two ticks, Impairment I (1).
- The 1st video shows the skill being used normally with no back attack.
- The 2nd video shows the skill used as a back attack.
- If you couldn't quite clearly catch it, here are snapshots of the impairment bar.
- In the 1st image you see that the impairment bar is just in between the r and the a.
- With the back attack, the impairment bar is now just above the e.
- Conclusion: Impairment is increased when back attacking with impairment skills that allow it.
3. How is Impairment Scaled?
- The same DH rifle skill also has a tripod which increases the impairment effect from II to III (2 to 3).
- So let's compare how each impairment level compares.
- This video shows the impairment effect with the relevant tripod slotted.
- If you couldn't quite catch it, here are the comparison images of Impairment 2 vs Impairment 3.
- Impairment 3 has 1.5x the effect of Impairment 2, so 3x the effect of Impairment 1.
- In other words, 3 is 1*3, 2 is 1*2. :)
- Conclusion: Simply stated, impairment is scaled linearly.
4. How Impairment Behaves When Skills Deal Damage in Ticks
- This is a grey area and I'm not exactly too sure about it, but here is the (short and simple) research.
- The DH rifle skill used above also has a tripod which doubles the grenades fired.
- So let's compare how this makes the skill behave.
- If you couldn't quite catch it, here are the comparison images of single hit vs double hit (Impairment III).
- Pretty simple to see. With the double hit tripod, each hit has an impairment effect of 3.
- The matter is not settled yet though. Let's take a look at a bard's stigma ability.
- Both Great Disaster and Stigma are Impairment II (2) skills, but Stigma deals its damage in multiple ticks.
- To summarize, stigma dealt the same impairment effect even though all ticks of damage hit the boss.
- Though, each tick's impairment effect was added to the total final impairment effect.
- So if you miss a tick of damage, you won't reach the full impairment effect.
- You might be thinking that we can come to a general conclusion now, but we can't.
- The conclusion being that if the skill originally deals damage in ticks, the impairment effect is spread out.
- And if it's made to do one more tick through tripods, each tick applies the full impairment effect.
Inconsistency
- To refute my conclusion above, I use two videos comparing 2 BM skills.
- Since I have never played BM before, I am only going off the skill descriptions.
- The two BM skills I am comparing are Phoenix Dive vs Dragon's Ascent without tripods.
- Phoenix Dive is Impairment I (1), while Dragon's Ascent is Impairment IV (4).
- Both skills deal damage in ticks, so one would assume the impairment effect of DA is 4x greater.
- Also the reason why the BM skills seem to have a greater effect is because the boss is different.
- If you couldn't quite clearly catch it, here are snapshots of the impairment bar.
- The bottom image is of Dragon's Ascent, which deals damage in ticks and has a total impairment of IV (4)
- The top image is of Phoenix Dive, which says it has an impairment of I (1).
- Phoenix Dive says the damage is dealt in two ticks, and so total impairment level reached would be I (1).
- This is not the case though as you can see in the video.
- Dragon's Ascent should be 4x the impairment, but as shown has only 2x the impairment effect.
- So even without tripods, each tick of Phoenix Dive applies an impairment effect of I (1).
- Conclusion: Skills need more clarity and consistency.
Another Example
- Let's take the Bard skill Holy Sound. It has Impairment II (2). It's been a while, so feel free to correct me.
- The 2nd tier tripod for the skill increases duration by 1.5s, meaning more ticks of damage are fired.
- Since each tick adds to the final impairment effect, adding more ticks means more total impairment.
- So increasing the duration here of the skill, makes the impairment higher than what it states.
- The 3rd tier tripod for the skill reduces duration by 50%.
- But this just means that the same amount of ticks are fired in a shorter duration.
- The increased impairment effect you got from the 2nd tier upgrade did not disappear.
Conclusion: Skills need more clarity and consistency.
