Level 92 Necromancer^3.25

Notes

You can find the full and very detailed written guide here https://maxroll.gg/poe/build-guides/chaos-minion-army-necromancer-league-starter

=== CAP RES & DEX & INT WITH GEAR ===
Spectres: Use two Carnage Chieftains from act 2 until you get  Arena master & Pale Seraphim & Perfect Forest warrior  (lvl25 spectre gem)  (ask in /global 6666 for spectres)

Early league start 3 spectre limit

1. Carnage Chieftain (act2 in "The old fields")
2. Arena master (Drox map)
3. Pale seraphim (Beyond mechanic)  (Replace this with Perfect forest warrior (damage) or Perfect guardian turtle(defense) or Perfect judgemental spirit (Def + dmg) as soon as possible)

Before you get perfect forest warrior culling strike support with your spectres is a good option.  4L (Spectre-phantasm-cul-holy relic) drop faster attacks or drop holy relic if you want to keep faster shield charging.

1. Carnage Cheiftan (act2 in "The old fields")
2. Arena master (Drox map)
3. Perfect Forest warrior (Damage) 
4. Perfect guardian turtle (Phys Defense) or Perfect judgemental spirit (+ES & +dmg, the stronger option but see Note)

Note: Perfect judgemental spirit can die to elemental reflect maps if you have a lot of map % increased effect, mine died on a map with 30% elemental reflect when it attacked with its fire spell into a very large pack (Skip ele reflect maps if you use it)

Try to over cap your resistances with +15 to negate elemental exposure.

If you get a white gem slot where you have faster attacks linked with shield charge you can easily change between faster attacks and Enduring cry when you do bosses. (This is a must for HC)

Minion skill GEM LEVEL is much more important than QUALITY:  21/0 >>>> 20/20    Spectres/dps golems/skeletons/zombies/phantasm/AG

There is a div card that gives 21/0 vaal skeleton called "The Bones"

You want one ghastly eye jewel with taunt on hit and one with bind on hit 

You want "minions have a chance to poison on hit" on all your ghastly eye jewels to reach 100% chance to poison with minions. This is a massive damage increase.

Dont use AG until total combined gem level for AG is at least lvl 20, "total combined gem level" =  +1 skills from wand/helmet/shield/+socketed gem lvls on ring.

If you start mapping with bought or traded low level(1) minion gems you will have a very bad time.

Wake of destruction shock effect is 15% but the uptime is very unreliable so shock effect is set to 5% instead

As soon as you finish hungry loop your AG will become very tanky. 

Swap to Solaris pantheon if you are going to fight end-game bosses that are mostly alone (Shaper/Eater/Exarch/Sirus/Uber elder/Maven)

!T17 MAPS! Skip the abomination map boss until you have at least medium budget setup. (They can destroy your permanent minions and AG in seconds if you are unlucky)

Convocate on top of tanky rares / bosses to focus dmg and to move your minions away from uber attacks that do a lot of damage. (So dont use convocate with automation / trigger / cast when damage taken)

LOW BUDGET NOTE

Dendrobrate is a good cheap option until you get enough "minions have a chance to poison on hit" jewels. (Get extra dex and Int from jewels, cluster or ring if you need it)
If you have more than 60% "minions have a chance to poison on hit" from jewels swap to covenant as soon as possible.

Dynamo is a very cheap anoint you can get early for increased mana regeneration, increased maximun mana and increasing the duration of your guard skill.
You want to anoint Death attunemnent later when you can afford to get a Silver oil.

Helmet implicit can be "minions have increased maximum life" instead of despair curse effect if you want tankier minions.

If you hate using melee skeletons swap it with carrion golem of hordes or try the skeleton archers(change multistrike for withering touch). (Changing will do less damage and is not recommended)

Use +1 to socketed gems on the ag unset ring if +2 or +3 is to expensive.

Dont level precision and vitality to high, keep mana at minimum 73+
Why?  (Shield charge (8mana) + trigger flesh offering (65mana) = 73mana)

Later when you get Immortal call linked with increased duration you want to have minimum 85 mana, preferably a little more.

For low budget AG body armour and boots use either Cospri + wake or Garb + windscream (Garb is more expensive but makes you crit immune)

Low budget end-game can do Uber Atziri/eater/cortex(depends on mods) if you play well and Uber Sirus&exarch if you play very well (Get medium budget before doing uber uber Elder/Maven/Shaper, or play like a pro)
(If you play Hardcore, get at least the Mid gear for 100% Spell Suppression)
Difficulty Ubers: Atziri<<<<Cortex(Depends on mods)<Eater<<Exarch<Sirus<<Elder=Maven<Shaper
Uber shaper+elder+Exarch+Sirus can wipe your minions at a low budget. (Make sure AG gem is lvl 21 before doing ubers)
Vs Uber Sirus respec into protection mastery to get corrupted blood immunity.

MEDIUM BUDGET NOTE

Helmet implicit can be "minions have increased maximum life" instead of despair curse effect if you want tankier minions.

You no longer need minion blind on hit jewel, precision aura or accuracy on a jewel/wand. (This is mitigated by +2 extra skill levels, 1 from Ashes and another from a +2  wand)

Make sure Ashes + Vaal summon skeleton has a combined quality of 40.
For example 15 for gem and 25 from ashes or any kind of mix between that. (There is no reason to have higher than 40 quality for skeletons/zombies)
