PoE Vaal Detonate Dead, Single-Stomach-3913 builds

This is my take on the Vaal DD ignite Necro. Tried to minmax abit, the clear isnt that good. But the single target is really nice, dont know if theres any other way to clear better. Tried with abberaths hooves. didnt seem to change much imo. Heres the PoB, would love some comments for improvements on both gear, tree and gem setups PoB: Tried some simulacrums, and felt squishy against elemental damage, especially the phys as extra of any element. so i went with the Divine flesh, divined it until i got the Cult of Chaos for 1% max
