Petrified Blood is a spell that reservesmana to protect the character's life in the low life threshold by causing a portion of the immediate life loss from hits to be lost over time instead. At higher skill levels, the amount of life loss over time is reduced, even though the percentage of immediate life loss prevented remains constant. As a drawback, the character cannot recover life above low life by any means except with flasks. Skills also gain an additional life cost while the character is above low life.
"Life Recovery other than Flasks cannot Recover Life to above Low Life" is a weird way to say, "Life Recovery other than Flasks cannot Recover Life above the Low Life threshold", this means Coward's Legacy will not allow you to fill your life to the normal maximum, as the threshold is unchanged. The life mastery that changes the low life threshold to 55% however, WILL let you recover to 55% as it affects the threshold.
With your Low Life threshold at 55%, the amount of damage it takes for you to get oneshot at maximum low life goes from 83.33% of your maximum life to 91.67% of your maximum life.
Petrified Blood will only protect your life up to your low life threshold, and will not affect damage redirected to energy shields or mana.
You cannot directly mitigate the life loss over time from Petrified Blood in any way, not even from sources of damage immunity like a Divine Shrine.
Life leech will attempt to recover life past the low life threshold. Since leech only ends when you are at maximum unreserved life, this effectively gives you an "overleech" effect like Brutal Fervour, as long as you have more unreserved life than your low life threshold.
In the same vein, The Agnostic will continuously drain your mana to recover life, since it can never recover your life to full.
Options - Petrified Blood can be used with different options. For example it can be used while on full life with no life reserved. This allows for characters to be able to survive more damage from one single hit (or multiple hits). Life flasks are the only way to gain life above low life when using Petrified Blood. Other life gain sources will continue to work if temporarily dropping into low life.
Master Surgeon lets the Pathfinder Ascendancy class make use of Petrified Blood while keeping themselves above low life most of the time. Any damage taken that exceeds the low life threshold is reduced, increasing the amount of damage it takes to get oneshot by an attack.
Petrified Blood will not interfere with Cast When Damage Taken setups.[1]
