Life leech cap and Ghost reaver interactions?

I know that you can max life leech for 20 perent of max health each second.

What hapens to this cap when you use Ghost Reaver, so your life leech works on Energy Shield instead? Does this remove cap or make cap of 20 percent of max energy shield?

Also what happens then if you use passive skill "Vaal Impact"?

Hope some clever heads out there can help me :D

I'll say it'll consider your max energy shield instead of hp, since other passives seem to have similar functionality when being switched over to energy shield.

So it'll be capped at 20% of your max energy shield per second, and vaal impact will make it instant regardless of value.

thanks for the reply. seems like the both + CI if you have enough energy shield could be a good combo then... Then have life leech on big damaging spell. :)
