So I was testing the wind of death weapon, I discovered the following:
- increased damage enchantments (physical or elemental) apply to the self inflicted damage (so with 100 hp and 2*5% self inflicted dmg if using 10% increased physical dmg I would get 10 dmg + 1 dmg)
- when using a fire infusion on this weapon, it appears that when an enemy dies of fire dmg, the weapon applies the self damage infliction (but not for example life steal, so this would kill me while actually hitting an enemy at low health wouldn’t
(You can see the 11 here, this should be 10 normally, I have a mottled black gem on the weapon, but its boosted by 1 armor piece with 10% increased fire damage)
Kind regards
Can confirm, saw this happen live.
Good find, thank you both for reporting!
I will escalate this now.

description:
sometimes health gain effects stop applying entirely — including health on kill, health on parry, and lifesteal. restarting the game restores normal behaviour
max hp 370
current hp 171 (doesn’t go above 171 because of reduces max hp negative enchantments)
sword hit takes away 5% of max hp = 370 * 0.05 = 18.5
9%*1.4 health on kill = 370 * 0.09 * 1.4 = 46.62
enemy dies in one hit
hp after hit should be 171 - 18.5 + 46.62 = 199.12 (but capped to 171 so should be 171)
instead hp after hit = 144
hit #2: edited: bad example
20% lifesteal gem enabled but i was not counting that, mainly concerned about the hp-on-kill
healing-related effects are intermittently failing, and attack type changes the visible result
not sure how to reproduce - it happens randomly, doesn’t seem to be related to anything
it’s true that’s possible
i actually didn’t see the 2nd kill in the video properly - my bad, recorded a while ago and forgot what actually happened
but it’s also happened in some sessions where HP on parry didn’t heal after a parry - no wind of death involved
i’ll return with a clearer example
i unequipped the lifesteal ring
here my HP went from 155 to 174 after killing the mob (p.s. good action shot)
the self-damage actually shows up as 28 which is 7.5% of 370
that would make sense if i had a mottled black pearl in the sword, but i don’t
the HP on kill works and everything matches with the self-damage
sorry about the muddled bug report, something felt off and i wasn’t looking at the damage numbers
went back to check out those healing shenanigans:
max hp: 167
tooltip lifesteal: 20%
(real lifesteal ≈ 3.4%, ≈ 5.2–5.5% with healing chest)
healing chest piece: +35% * 1.5 = +52.5% healing
with healing chest
self damage: 30 per hit
hit1:
hp before: 103
hp after: 91
damage: 315
→ heal ≈ 18 → ~5.7% lifesteal
hit2:
hp before: 87
hp after: 127
damage: 1280
→ heal ≈ 70 → ~5.5% lifesteal
without healing chest
self damage: 26 per hit
hit1:
hp before: 108
hp after: 91
damage: 267
→ heal ≈ 9 → ~3.4% lifesteal
hit2:
hp before: 94
hp after: 141
damage: 2163
→ heal ≈ 73 → ~3.4% lifesteal
hit3:
hp before: 144
hp after: 141
damage: 2042
hit4:
hp before: 142
hp after: 141
damage: 1022
this all makes sense if:
→ heal happens first → capped at max hp → then wind of death damage is applied
my max hp ≈ 167
167 - 26 = 141
so those “no heal” hits are actually:
→ heal to full → then self-damage brings me back to 141
i’ve been reading it as “sometimes healing isn’t working”
conclusion:
-
tooltip 20% lifesteal = ~3.4% real
-
with chest = ~5.2–5.5% real
-
healing chest works (≈1.5x multiplier)
-
lifesteal is applied before self-damage
-
overheal gets wasted at high hp
not sure if this is a bug or working as intended. makes my glass wind of death build that much more glassy
thank you for pointing out messed up things in my first post and helping work this out !
I take it you always had Wind of Death equipped then?
Silas
yeah i always had it equipped. but i didn’t connect the dots since that was the first build i used since patch. now it’s all clear
I also had tested this, this appears to be true
This is what was happening! I was trying to figure out what was happening with this sword yesterday. 
I kept dying to the training dummy, and then I got the LS on bleed and slotted in a LS gem on the weapon.
Then I added the plagued ring for more LS since I have -50% max health. Then I equipped the serendipity ring for more heals and on top of that I even got another armor enchant for increased heals.
At that point when I attacked the training dummy I just watched my health go down to 1 hp and then it never killed me after that, it just juggles between 1 and 2 HP
