Help me fix my build

so i recently got shavs from the aesthete and 6linked it in 110 fusings , but nvm that i decided to do something LL.
I checked a lot of builds and came to the desicion ill do LL BV Occultist with poison/chaos using Obliteration and Profane bloom to clear packs and pack clearing is decent but single target damage is shit for t16 bosses for example. I wanted to try shaper and farm guardians but the only one i can kill is Minotaur and thats cuz he is easy af(and i know chimera and hydra are poison immune).
My thought is can i do something itemwise or on the skill tree that can boost my dps or i should return to crit bv with a few dmg auras and stuff, character name is GuwangShashou.
Currently using 2 curses and clarity + discipline and my ES with presence of chayula is 10.3k
