NECRO - help with build plz

i've always liked PoE and i ALWAYS have trouble getting one shot.

watched some videos, learned a bunch, but i'm still having trouble

i'm playing Necro, started playing with raise zombies of falling, and i've been struggling in higher content by getting constantly killed in one hit

this is my current character
https://pobb.in/aTHzlXmqqXZN

i tried using SRS also, but it didn't help me

i was using Chaos Golem instead of Carrion Golem, but since i've been constantly one shot, i just decided to go full damage instead

which items should i look for?
what can i change in my skill tree
