Disclaimer: This is not a good build. It requires extremely specific items, is finicky to play, and the damage (compared to the cost) is really bad. But it is still a perma vaal IC build, which is my favorite archetype in PoE, and that is what it takes to make it work at all after the massive vaal IC nerf in 3.16.

Main elements that make the build work:

• 100% reduced soul cost of vaal skills from weapon mod and legacy soul catcher with 140% flask effect, flask charge generation from Ascendant Pathfinder + Traitor keystone (same as many other vaal skill builds in standard)

• CDR from boots, belt, crucible weapon, Ascendant Saboteur, Temporal Chains Balance of Terror and a lot of abyss jewels + adorned (+ 1 That Which Was Taken)

• 17 endurance charges: 3 base, 3 from tree, 2*2 from recomb+synth rings, 2 from warlord + corrupt boots, 2 from crucible weapon, 1 from determnination sublime vision, 1 from tattoo, and 1 from unleashed potential forbidden flame/flesh

• endurance charge generation from replica farrul's fur
