Carrion Golem Necromancer 3.15
Max version has 89% elemental resistances and 7500 ES
Can easily do all content. Also allowed to farm 60-80% delirium maps

Mandatory belt

Belt price ~ 2 chaos at first day of the league

(Use Glassblower to add quality to Flasks)

Granite Flask with bleed immune

Quicksilver Flask (movement speed)

There are 2 Movement Speed flasks which are good for us :

Cheap

Expensive

Quartz Flask with ignite immune

You can craft it by using Alterations, might take 10-20+
Reduced charges is the best thing you can roll as Prefix

I would not recommend to roll it with alts, better to buy it

Jade Flask with freeze immune

You can craft it by using Alterations, might take 10-20+

6-Link Chest

Rare one or Tabula
Buy what is cheaper

6-Link would give you +40% dps compared to 4-Link

Add up to 20% quality to your gems by using Gemcutter's Prism

When you get those items feel free to complete UberLab
Would recommend to buy second Life Flask for this purpose
Buy Twice Enchant for additional use of the Divine Font if needed
Take Bone Barrier and put Bone Armour on left click for auto cast
Here you can find current UberLab scheme
Best helmet enchant is 'Summoned Carrion Golems have 40% increased'

Flask setup

Blood of the Carui or Life Flask with instant life recovery

If Karui Flask is too expensive - buy Divine for the first time

Clayshaper x2

Mandatory item
First currency you farm will be spent to buy 2 of them to finally switch to Carrion Golems

+1 to max number of golems each
4-8 chaos at first day of the league

Once you have them - rebuild your gem setup :

Enemies Maimed by zombies take (10-14)% increased physical damage
Blood Magis allows spectres to always cast their buffs
Vulnerability is cast on bosses to increase DPS
Flesh Offering to increase minion's attack speed
Pride doesn't work with generosity, doesn't matter if it's linked together
Second Blood Magic is for 'No mana regen' mod
Animate Guardian is leveling
Hold Desecrate at stash tab and use to create Spectre if needed

At the time of purchase 2 Clayshapers - take Golem Commander node to have +1 to max number of golems

Now you can have up to 4 Carrion Golems and should get new spectres instead of Slave Drivers
Move to Ashen Fields (Act7) and summon 2 x Carnage Chieftain for Frenzy Charge generation and 1 x Host Chieftain for Power Charge generation
(Use Desecrate, Hold 'A' , and select the correct corpse)

Abyss jewels x2

If jewels are too expensive - decrease the roll

This setup would allow you to farm T1-T13 rare maps
