I haven’t found information regarding this.
Does anyone knows if EoR triggers life steal? From the skill description on grim tools it reads “…as long as the Oathkeeper channels their focus into the attack”. Which makes me think if it counts as an attack it will trigger life steal, right?
Thanks! 
It has weapon damage so it should have life steal. Just remember that weapon damage below 100% reduces the life steal accordingly. So if you have 7% life steal and 10% weapon damage you only get .7% attack damage converted to health, iirc.
Thanks mate! I guess it’s still good.
It’s actually not. You still got full adcth even if the skill only has 10% WD

If this is true, that’s a bug. ADCTH is supposed to be modified by Weapon Damage values under 100%.
Yeah, ADCTH passed through weapon damage gets weaker when it starts to go below 100%. 10% ADCTH passed through 50% weapon daamge becomes 5%.
Someone tested it from way back, I forgot. But it’s clear from his/her test that you still got full adcth even if the WD is less than 100%.

From experience and testing, it doesn’t. This can clearly observed with Phantasmal Blades with the transmuter and no points in Heart Seeker. Get some ADCTH and you’ll notice you hardly heal. Same for low weapon damage skills like Flame Torrent which would heal like crazy if ADCTH healed at its max effect regardless of weapon damage.
I thought the result was that the life steal % applied scales with wpn dmg but it applies to the whole skills direct damage and just not only the wpn dmg component of the skill?
I always thought ADCtH doesn’t scale, but heals off the full percentage of the skill. If you have 30% WD, and 10% ADCtH, you heal 3% WD as health (base damage not included).
Grim Dawn is sure mysterious.
If it has built-in ADCtH, yes, otherwise base damage not included, as far as I know.
Well that is what that dude tested, that global adcth is scaled with skills wpn dmg % and then applied to the whole skill direct damage.
Let’s say you have 10% life steal from gear, devos etc. and uses a skill with 50% wpn damage and 1000 flat direct damage. Your weapon damage is 3000
Skill deals 0.5*3000 + 1000 = 2500 damage
Skill gets 0.5*10% = 5% adcth
Skill steals back 0.05*2500 = 125 life/hit
I think this is what the test showed.
Otherwise we would only steal
0.05*1500 = 75 life/hit
I think it’s 5% of 1500 tbh. Which is why you don’t see people stacking adcth on casters.
There are some notable exceptions like chillspikes and biting blades where the lifesteal is applied to each projectile.
So for example, since biting blades boomerangs back, it actually deals 140% WD, and so you’ll LS for 140% of what you have.
This is why I’ve been struggling hard to make a chaos biting blades build with fang of chthon + darkblaze amulet.
So far, no dice due to poor RR from items and an inability on my part to find a solid support skill.
My memory kind of mixed up at some point.
Yeah I think that’s the case. Adcth apply to the damage of the whole skill, scaled with how much percentage of WD in that skill.

Yeah I agree with you, if what Malagwalpoochaha is right, how come almost none uses ADCtH on casters? If you have any WD, you could still heal from the base damage, but no one picks it, so I think it’s not true. Although, if tests show otherwise, then it would be stupid to not believe it, I think. 
The only time adcth applies to caster is with ghoul. Apparently it’s now meta to use ghoul on casters.
Also note that I think biting blades is the perfect spell to stack adcth on since it penetrates any and all enemies
You need WD in the first place, if skill does not have WD you can not link adcth on it
I can try to find the thread where a dude did some serious testing regarding this.
Exactly, so if skill has 0% Wpn dmg, you get 0% of your global ADCtH
And if skill has x% wpn dmg, you apply x% of your global ADCtH to that skill’s flat damage
That was the result of that said dude’s testing. Now I really need to try to find that thread, think I have bookmarked it
And look I AM NOT CLAIMING / SUGGESTING ANYTHING I simply said that I recall that I read somewhere in a thread where someone did serious testing regarding this.
What?! Is the adcth from the ghoul proc different from other sources of global adcth ?
So do you suggest that Trozan Sky shard will steal life if ghoul proc is activated?
I used Haunted Steel on this PRM build, worked decently well even with just the 16% WD from the medal. It was good enough to sustain myself in Glad 170, even on HC.
As for the topic: I’ve always thought that flat damage on skills is just counted as skill damage, whether’s it’s on a spell like PRM or on an attack like Fire Strike.
That means the flat damage on those skills shouldn’t leech, unless they specifically have a transmuter or modifier on the skill that gives it leech.
The exceptions are DM, LA and Soul Harvest that specifically mention they affect all attacks.
A modder could verify this by altering a skill to very low WD% and increasing its flat damage. If you still get good amounts of life steal with that setup, it means that the flat damage leeches. I don’t think it will though.
If this were true, my cyclone would be God. and Torrent would be God. Pyroclasm God, Elemntal balance…you get the point. But i’ve been wrong before so it should be confirmed
Denis M. tested ADCTH . Your effective lifeleech is reduced to %WD below 100%, but you leech at full skill dmg, not only your %wd component.
Aslo, im sure that you cant leech from Soul stuff, cause it has no %WD on it.
