[2.4] Necromancer of many

Completely new equipment, some tree rework, higher lvl, bosses progress

Lvl88, Atziri, Uber Izaro, T11 maps

Moooreee. Goal is to summon as many minions as possible.
Our only concern is to support our legions. We'll have no time for direct attacks.
1. It is PURE summoner - no direct damage (Ancestral Bond)
2. It isn't "wait while your minions do the job" build. You have stuff to do.
3. It is really hard to control. Effectiveness depends on you own skill.

Chest: SRS double totem. Main damage source. Spirits spread over entire battlefield, attacking everyone.
5L: Summon raging spirit - Spell Totem - Increased duration/Faster casting - Minion damage - Melee physical damage
6L might be complemented with Melee physical on fill life, Multistrike, Melee splash, Increased rarity. It's not easy to color ES armor for this link.
Faster casting pumps skulls faster, but Increased duration is more efficient. But again, coloring problem. SRS amount should be >40.

Helmet: Raise Zombie meatshield. Currently have 10 zombies. "+2 lvl to minion gems" and Empower for more HP. Take damage, kill common mobs.
4L: Raise zombie - Minion life - Fortify - Empower

Gloves/Shoes: Summon Skeletons. Currently up to 14. Our only targeted 'attack'. Summon them wherever you need reinforcement: pump damage on boss, help zombies in defense, destroy "cannot die" totem... Our most controllable forces.
4L: Summon skeletons - Minion speed - Minion damage - Melee physical damage
I don't like Spell echo here - it reduces our maneuverability and doesn't pump damage.

Gloves/Shoes: Raise Spectre. Currently have 4 specters. You are free to choose spectre monsters, but physical based are better. I am using giant statues for tanking even where zombies are falling.
4L: Raise spectre - Minion life - Minion damage - Summon * golem
Lightning golem is only team-friendly golem. Additional support for spectres is better, but I just like this guy. 1 more minion type =)
Chaos or Stone golems are useful too.

Hand: Auras
2L+1: Hatred - Generosity | Discipline
Hatred with generosity and aura passives grants huge damage boost.
Discipline for defences.

Hand: [de]buffs
3L: Any offering (I am using Spirit) - Any curse - Increased duration
Enfeeble seems to be the only curse that works properly.
Flesh offering may help to pump SRS amount. But Spirit grants nice chaos damage, ES for us and helps to max everyone's resistances.

2 Unset rings and Black Maw Talisman:
Desecrate, Convocation, Clear Mind
Black Maw with Clear mind is optional, but it helps with mana and grants damage/speed (Commander of Darkness)
Desecrate for offering.
Convocation for tactics: retreat or instant meat shield

Ancestral Bond, Necromantic Aegis, all minion nodes, duration, survivability, auras.
Ascendancy: Commander of Darkness, Flesh Binder, Mistress of Sacrifice, Soul Weaver.

My current equipment:
Midnight Bargain - zombie and spectre
Bones of Ullr - zombie and spectre
Grip of the Council - damage boost and nice stats
Victario's Charity - epic shield for Necromantic Aegis
2 unset rings and Black Maw Talisman for gems
Helmet - +2 minion
Stats from non-unique equipment - helmet, chest, belt, rings, amulet - life, es, resistances.
Non of this equipment is vital.
It might be a good idea to gain chaos resistance.
Skullhead is usefull.

Refresh totems, summon skeletons, create-consume corpses, curse enemies and stay close to battle (to grant auras). In difficult situations you will also need to raise new zombies. When retreat, cast convocation to regroup and heal zombies. Convocation does not affect skeletons so they will hold enemies for a while.
You will need to perform MANY actions in battle.
And don't die - you are the weakest point of you army.

Level 88.
Killed Atziri at the first attempt - never even saw her before. Have died 2 times.
Killed Uber Izaro. It took a time to adapt, but in the end - nothing extremely difficult.
Clearing up to t11 maps without problems. Just don't have higher tiers yet.
Gems are still lvl 19 (without quality). Empower is not leveled.
Chest is 5L.
Average clear speed. Most of deaths are caused by my own carelessness.
I feel absolutely comfortable most of the time.
Complex and interesting gameplay. Lots of skills, lots of things to perform and to track. And I like it.
