After carefully reading on how “life steal” or “ADCTH” works from this page
I’m lead to the conclusion that Blood Boil doesn’t increase the amount of health gained from Siphon Soul as it’s not direct damage of the skill but an augmentation.
Can anyone clarify this for me? As I only use it for it’s overall healing aspects and not damage being able to save points and not kill things faster with it would be a plus.
