Wich build is good for me?

Hi there, my favourite class is witch necromancer. I always make sure to have enough rarity of items found on my items i wear. I always play with zombies and srs because it's easy and chill to play for me. Up until now i played my own build but i struggle with e.g. delirium or some T16 bosses and sirius is undoable for me and also the conquerors i need often help with. I'm here to ask for an recommendation what build can be proper for me. What i'm looking for is: enough life for not to die in high lvl content, rarity of items found, minions - i like this playsyle, i want to focus on items to drop, not on monsters too much, minions should do the work for me hehe... i need no fast clearspeed and to kill sirius is not the main thing, i want to do all high lvl stuff like delirium, legions, delving down and get T16 Metamorphs down.. because i very often die on this juicy stuff and then all the wealth drops are gone. :(

Okay in short: I need: high survivability, minions to do the work, i want to do all high lvl stuff without dying too often, i dont need the fastest clearspeed, i play slow but want to do all with ease and not to die with minions. ^^

Ok ty :)
