zealot's oath, life leech

i have zealot's oath, and my armour gives me 1% of attack damage leeched as life. does this life leech go directly to ES? or do i have to have Ghost Reaver for it to go to ES?

You need ghost reaver for life leech to apply to energy shield.

And to answer the other question which probably could have been in this thread is no, life gain ok hit is not regen and will not work with zealots oath.

While it was implied by the previous poster, life gained on hit is also not leech, so not only Zealot's Oath but also Ghost Reaver does not apply to it. As far as I am aware, there is currently no way to turn life gained on hit into Energy Shield.
