Life leech not always working?

Hello there. I don't suppose someone might have an idea of why my Lightning Strike Slayer sometimes stops life leeching, and in some cases can't leech rare mobs at all?

Before writing this opst I was on the way to killing the boss in the tier 13 map Desert Spring. At the end of the road for the last boss area, I stopped leeching on a normal scorpion mob and died. After getting back I let it hit me a bit, and was now able to leech from it. The map was magic tier with the "X extra magic monsters" modifier. I'm starting to go insane because of stuff like this, because it happens juuuust often enough that I can't level up anymore.

Earlier today I also encountered a rare mob in tier 15 map The Pit. It didn't have any "can't be leeched from" or some such under the name. Soo, any explanation? All the other mobs was leech'able.

There could be a multitude of reasons. My guess is that since LS is an attack skill, if your accuracy in the Character Menu isn't 100%, you can fail to leech when your attack doesn't hit. The game calculates the monster's evasion against your accuracy and even though the beam "hits" the target on screen the monster doesn't take damage.

Only way to stop it is taking Resolute Technique or getting a weapon with "hits cannot be evaded" mod.

What's your source of leech? Attack damage? Physical damage? Lightning damage?
There are many reasons, other than the obvious (can't leech mod) that could affect your ability to leech:
- Dealing no damage (blocked attacks, missed hits, etc).
- Being out-damaged by damage over time (you mentioned scorpions, it could be that your leech is so low that your leech gets outclassed by the poison, or you could be using some form of self-inflicted damage like flasks or Blood Rage).
- High enemy resistance to your damage type that leeches.
- Something affects your life recovery rate from leech and it looks like you're not leeching.
- Something prevents you from leeching beyond a certain threshold, like Petrified Blood does or that mod from monsters that gives them a red circle around them.

I might've just been very unlucky then. Main Hand chance to hit says 91% and Main Hand chance to hit evasive monsters says 81%. But I assume it's likely even lower because of the Evasion of the mob. So that could explain times like that. But I doubt it's the same explanation when I spam a rare for 1 min and not a single leech goes off.

But thank you for the explanation on how hits work :)

Correct me if I'm wrong here, but isn't there a rare monster modifier that prevents leeching?

Anyhow, as others have said, there may be a lot of reasons here, and your low hit chance is absolutely one possibility.

For more context, I'm using this guide https://pobb.in/ClhFTftbn_Jb (or google "Level 99 Crit Lightning Strike Slayer" and click the first link)

In short: Yes. I have Vaal Pact (dunno if that is important), From gear I have 0.2% of lightning damage leeched as life (and my weapon has 32-511 lightning damage with an attack speed of 1.71). 2% of physical attack damage leeched as life. From the skill tree I have 2 nodes that gives 0.4% of attack damage leeched as life.

With the scorpions, I might've just been very unlucky, and the few hits I'm 100% connected (visually) was actually dodged.

No, my life was steady, so not poisoned. I died from the melee hits because I let it walk up to me because I expected to heal a ton of HP like I usually do. Also, I don't have any self-inflicting stuff.

Wouldn't there still be SOME life leeched?

I'm not sure what you mean. But with the few rares, I have literally double Dash away, Shift+Right click on the rare, looked at my Health Orb, and it doesn't move.

I don't use that spell myself. Dunno if you ment the mob might have it though. I kinda remember seeing a red circle around some mobs, but I'm also 99% certain that the specific rare I encountered earlier today didn't have it.

It would seem you are currect. "of Congealment" "Enemies Cannot Leech Life From you". Now I just have to look out for the names to confirm if this is the issue regarding the rares.

Thanks for your time :)

We'd have to look at your actual build (unless you already have the exact same items as the guide).
While Progenesis is not self-inflicted DoT it works the same, by the way.
Although Vaal Pact and attack damage leech kind of throws most of my theories out the window.
So it's gotta be hits missed (in game numbers are just an average, it doesn't mean you're going to hit that % of times).


A side crazy theory would be package loss / connectivity issues.

Maybe you could try using Resolute Technique for a while to see if this phenomenon repeats. That would confirm whether or not acc. rating has anything to do with it.

I think I have unpriveted my account now (didn't know it was a thing until your post). But I might have figured out the rare mob issue. I can't recall all the encounters, but today I met one of the crystalized mob groups where the rare couldn't be leeched from. I took a screen shot and googled the effects, and at the very least in this case, it's because of "Remnant of Corruption". Apparently one of the effects from the corruption is that it can't be leeched from.

I'll keep looking our for non leechable rares, but it might just as simple as: Scorpions was unlucky and all the rares had Corruption.

Thank you very much for your time :)

Edit: But feel free to look at my char (if I unprivated) and see if you can see something that might be an issue.

Nothing is jumping out to me on the POB. I think the suggestion that has been made about the accuracy is a good candidate, however if you are doing damage, I would think you would be leeching.

Something that comes up on the gameplay forum is unholy might. That is not the case here with attack leech and elemental damage. However it is an example of a thing that occurs intermittently and can interrupt leeching, because of the damage conversion.

It could be something to do with the leech being instant, i'm not familiar with using Vaal pact now or how it was in the past.

There is a lot of Degen in the scorpion fight. Pretty sure it is chaos Degen as well, which you have negative chaos res. I would think you would still be able to see the instant leech chunking in, but maybe there is a point where it is overpowered by the degen on the tick. I'm not very familiar, I wouldn't think that is the case, but maybe what ever is happening, you notice it more when there is degen.

Yep, that all sounds logical to me. Probably was a combination of these things under different circumstances.
