Graven's Secret unique belt

Hey,

Just wanted to ask if you have good ideas on this unique belt-


When i started to theorycraft it first mentality was to fully exploit this item recovery (160- 200% es recovered from ele damage taken), which would look like this- 10k es CI, at least 60% physical damage taken converted to elemental (taste of hate 20%, watchers eye purity 12-36%, helm 10%, maybe lightning coil 30%?? or chieftain 15%), transcendence with smth like 20k armour.
However there is a hard choice for a chest piece- beast fur shawl for 40% increase es recovery, lore weave for fixing transcendence, or lightning coil for dmg convertion. Either way i found it really difficult to fit everything into build (ascendancies i looked into was chieftain, trickster and scion-trickster), maybe you have some better clue how to do it, would like to hear it.

Thus i went to look for more humble use of this belt. Its either EB+mom with just 3+ abosrption charges to fuel ES for MoM stuff or what im doing right now is- corrupted soul with 6+ charges (with scion-trickster 70% es recovery). It works kinda well, for every 1 hit 100% elemental damage taken which is split in half (50% to es 50% to life due to corrupted soul) around 122% is recovered and so every ele hit heals es for 72% of hits damage, but no phys mitigation apart from block and flasks. Thou the build is just in white maps so far, cant tell if it will be good later on (char called bloody_days if interested, stats are crap, just experimenting).

What are your thoughts on this belt?
