Is the Shavronne's Satchel fine belt buggy?

I tried this unique belt and it says life recovery from flasks also applies to energy shield.
Feels like same with Eternal Youth passive node (Life Recovery from Flasks applies to Energy Shield instead) but even better.

But the reality is the energy shield never get the recovery from flasks.

Any suggestion?

The energy shield restoration based off of flask health restoration amount apparently stops when a player's health reaches maximum. Which essentially makes the belt pretty crappy unless you somehow have a high amount (maybe like 25-50%) of "incoming damage is taken before health before energy shield" value, which as far as I know is not possible. (there's a helm Atziri's Disdain that's 10% bypass, and the passive node Heavy buffer which is a 5% bypass).


However,

When I combine Shavronne's Satchel Fine Belt with my Pathfinder's Enduring Elixirs ascendency passive, it works as one would expect. The enduring elixirs passive gives: "Life Flask Effects are not removed when Unreserved Life is Filled. Life Flask Effects do not Queue".

It sort of turns your pathfinder into a health+ES stacking character that wants to put points into passives like Heavy Drinker, Combat Alchemy and Staunching.

The key thing to make it all work however is that you MUST have 1 jewel that has "6% of skill mana costs converted to life costs" so you can keep your life fluctuating between 99% and 100% when using skills, thus enabling you to repeatedly spam your life flask to keep energy shield restored.

It works quite well. However, I'm still unsure if it's worth using pathfinder for this combo over something like a gemling and then just using eternal youth passive. Pathfinder ascendency choices are really truly bad 😒 except for this one combo with enduring elixirs and Shavronne's Satchel.
