Calculating The Retch DPS

I'm looking for help calculating DPS for the unique belt The Retch which takes 200% of your leeched damage and turns it into chaos damage.

The current character I'm trying to work out the DPS for can be found here:

I'm using a slayer with Brutal Fervour so leech instances don't go away once I hit full HP.

My understanding of the damage calculations is that the retch only cares about 3 leech modifiers:

1. How much percent of hit is leeched

2. How Much maximum percent health a single leech instance has to fill before it falls off

3. How much percent health per second a leech instance is filled with before it hits maximum and falls off

My current leech stats are:

* 2.4% attack leech

* Leech Rate 8% per second( 100% recovery rate from vitality void cluster takes 2% base and doubles it to 4%. Vaal pact then doubles it again to 8%)

* My maximum % health for each leech instance is 20% ( 10% base + 100% from the Slayer ascendancy Brutal Fervor)

* The overall duration for a leech instance before it falls of is 3 seconds as the leech rate of 8% only need 3 ticks to exceed 20%.


With that all In mind I calculate the damage as:

Leeched Hit: 2.4 of 270k average hit damage = 6480

Leech damage multiplied retch : 6480 x2 = 12960

Damage x Numbers of hits that generate a leech instance a second : 12960 x 8 = 103,680

Total Sustained DPS in fight that last at least 3 seconds: 103,680 x 3 = 311,040

Are these calculations correct or am I way off somewhere?

The Retch only cares about 1 thing--the amount of life you actually gain from leech. It's not modified by anything else. So take your maximum leech rate and double it, and you have your maximum possible Retch dps. For example, if you have a 2k leech cap, your max Retch dps would be 4k. And that's before taking things like enemy chaos res and whatnot into account when applicable.

Simply put, it's a pretty poor source of DPS in today's PoE.

You can get it up to 240% with catalysts!

I ran the numbers as best I could a while back and yeah it's not very good. You need to have uncapped instant leech from a few uniques, then boost your health and maximum leech (not total!) as much as possible. Combine with lowering enemy chaos resist and wither, you can get maybe a million dps. If you try really hard.

Wrote a lot of shit about leech cap - but than i found this https://www.pathofexile.com/forum/view-thread/1676002/filter-account-type/staff/page/3#p14486862

Yes. Your total recovery per second from Leech is capped, but the damage to enemies has no cap.

Your recovery is capped, but the damage dealt from leech is done when you leech it nevermind how much you recover from it.
