I’ve noticed that with the necro and inquisitor, the flat health bonuses isn’t giving nearly as much life as they should. With +50% health, a buff that gives +1000 life should be +1500. I’m horrible at math though. So am I wrong or are the health buffs from these buffs actually not as good?
Intuitively - it should work - because +% health and the + from the buffs, does not have any tooltip that would explain otherwise. Can someone clarify this for me? :S
Uh, screenshots with and without buffs?
I’d like to have Grim Tools link personally. it should work, you’re probably just missing something.
The flat amount of additional health, that I see in an item’s description, is already upscaled by my +% health, isn’t it? Should be the same for skills?
No, it doesn’t work like that.
Neither? Good to know. So I will follow this thread curiously. 
Thanks! So it does work? Like I said I’m bad at math. I mean BAD bad. If it works as intended I trust you for it. Thanks for the clarification.
Yes, it works for me. I have
32% Health in total
After turning on Spectral Binding (+400 on the skill) I got
6364-5836 = 528
in-game.
528 / 400 = 1.32 = 132% which means I got 32% more out of this 400 on Spectral Binding which checks out
Then I add boots with 624 Health in their stats and my health jumps from 6364 to 7188
7188 - 6364 = 824 gain.
824 / 624 ~ 1.32 = 132%. Checks out as the real gain is 32% more than listed on the boots
All %Health bonuses
seem to be working fine for me both for item and skill bonuses
What made you think you got less HP in the first place? I mean, there’s a Mutator that reduces HP by 15% (total I believe), and some monsters have HP reduction aura…
