Progenesis + Petrified blood

defer damage taken to life over 4 seconds. If you have enough regen this is essentially damage reduction. Petrified blood provides 40% (+5% with anomalous, +12.5% with anomalous and ashes of the stars), progenesis provides 25%
65% deferral is like having triple life.
77.5% deferral is like having quadrupal life.

Sounds nice, but any petrified blood players have thoughts on this?

PB only protects health below low life. So assuming you stacked all that, and assuming it does stack like that, and you had enough regen/leech, it would be more like double EHP.

More likely it stacks multiplicatively, resulting in more like 68% of damage being delayed. X*0.425*0.75

gem wording: X% of Life loss below half Life is Prevented
flask wording: X% of life loss from damage taken occurs over four seconds instead

Yeah I guess they are multiplicative based on exact wording not matching. Good catch.

I guess in my brain they were both the same damage deferred stat.
