Does Life leech apply to bleeding?

[Slow ☣ Poison]

I have a champion build based on life leech.
I have some points i can spend to increase damage done from bleeding.
So does bleeding damage give life leech?
If so, are bosses prone to bleeding or are they immune?
Thanks

[Awesome!]

you cant leech from any damage over time effects. leech requires a hit. so you will leech from the hit that causes the bleed but not the bleed itself.

To be more specific, leeching requires a direct hit. So you have to do the damage yourself, this means trasp, totems etc. can't leech to you (or more accurately they will leech for themselves), unless you have a specific mod that allows that.

About bosses, they are not immune to bleeding.
