DOES PAIN ATTUNEMENT STACK WITH CHAOS INNOCULATION?

25 % more spell dmg when on low life
Chaos Innoculation gives u chaos dmg immunity,80 % more energy shield and life becomes 1 :)
1 life is low life but it's also "full hp " so do they work?
if not i guess blood magic rocks with pain attunement lol

I believe anytime you see 'low life' it means less than 35% and since you can never have 35% of 1 HP it wont work.

So than pain attunement combined with lots of energy shield to defend,+ Blood Magic right?:D:D
