There is a question about whether Life Steal applies to damage dealt by Thorns.
I'm asking about whether Life on Hit applies to damage dealt by Thorns.
These two are different:
Life Steal is "X% of Damage Dealt is Converted to Life."
Life on Hit is "Each Hit Adds X Life".
This question How does life on hit work? does not say anything about Thorns. So, here is my question.
Best Answer
No it does not, my life on hit on my Barbarian is 1200+ and with monsters hitting me I do not gain any health from their attacks. Also I do have thorns damage, it is currently around 265 damage, so I am doing some thorns damage that would activate it if that was the case.
