[2.6] Hybrid Baron Summoner Nercomancer (Zombie Focused)

Geofri's Sanctuary will give you flat energy shield based on your strength. This is useful for 2 reasons, the energy shield is scale along side your strength meaning you're gaining flat life from the strength with energy shield at the same time, and energy shield can be recovered without using flasks. Instead of having to spend portals for more flask charges, you can resummon your zombies to recover them then rely on your energy shield recharge keeping you alive. Just make sure you run out of danger anytime your energy shield gets low. You also get Zealot's Oath from the chest piece which helps keep your energy shield up.

Shaper's Touch
Does a few things that are nice for this build. The main thing is scaling your energy shield even higher based on strength. I was able to hit 4828 Life and 6264 ES with my current set up despite missing both life and energy shield on a few pieces and not using discipline. You also get a lot of flat mana meaning you can avoid mana on gear and also have just enough unreserved to resummon your minions as well as constantly summon either skeletons or summon raging spirits to direct your zombies.

Other than the helm, yes of course! Rare gear will make it easier to cap your resists and give you 2 slots for 40-50 strength. You'll be able to hit 1.2k strength a lot easier with rare gear meaning you have your zombies leeching to your life pool as well as 12 zombies (Or 6 with mon'tregul)

Chain and No Regen are the only things that are really bad. No regen is possible and I have done it, but you'll need a mana flask and you have to pay attention to how much you use your mana which is just annoying. Reflect might be a problem, but I never bothered trying since I didn't want to waste any maps. Totems is slightly annoying too if you get unlucky and have tons of Allies Cannot Die totems show up since zombie AI is a joke, but still doing of course.

The Baron (Duh)
Geofri's Sanctuary (For this Version of the Build)
Shaper's Touch (For this Version of the Build)
Alberon's Warpath (There is no reason to not use 18% Strength boots that cost an alc)
Violent Dead let's your zombies slam 90% of the time, making them able to actually clear a map
Brawn Crimson Jewel let's you multiply your strength by a lot, 6% per jewel slot at max rol. Might not be possible to hit 1k strength without a few but I don't math

Mon'tregul cuts your zombies in half but makes them tanky and powerful. I think it's the best choice after some testing
Astramentis gives up to 116 all attributes (Max roll) which is helpful in every way. A rare amulet does offer resists, life and energy shield however
Queen's Escape means you give up strength/life/ES on a shield but your zombies will move so much faster and you get an extra one. Without it, you'll want Flesh Offering up 100% of the time to not hate your life
Severed in Sleep/United in Dreams might be interesting since your minions do so much physical damage but I wouldn't bother with this type of build
Femur of the Saints makes you a niche build. +2 to your zombies in a 6 link is pretty nice plus attack speed for them as you summon more and more skeletons. If you find space for spectres then you get an interesting build
Grip of the Council is decent when paired with Queen's Escape since the movement speed penalty won' be noticed and the gloves do offer abit of strength. 20% extra cold is pretty nice too since our minions are mostly physical
Doon Cuebiyari offers 50-70 strength in the weapon slot. You can then socket a lightning skill to use Elemental Equilibrium and get a decent amount of power with iron will

Rush to first jewel socket and put in 1 Violent Dead (If you go for Non-Hybrid version, then either go through the int nodes or the mana regen)http://poeurl.com/bexx

Grab the second jewel socket for the second Violent Dead, then grab MoM for easy tanking while leveling http://poeurl.com/bexA

Go through the Templar area grabbing strength, life, and into the Scion Life Square. You can start using The Baron as soon as you have it. Skip the jewel socket for now. You'll use it for Brawn jewels but you need to make sure you have enough intelligence first http://poeurl.com/bexE

Grab the Minion Nodes above Templar and near Scion http://poeurl.com/bexE

I recommend grabbing strength to reach the extra zombies thresholds. Most strength nodes are close to life too, so you can grab some if you feel too squishy http://poeurl.com/bexQ

Grab the jewel sockets and fill them with Brawn Jewels. Make sure you still have the intelligence to use your gems. By now you can drop MoM and pick up some extra minion nodes on the right side of Witch and Might above MoM http://poeurl.com/bexO

From here there are a few things you can do. Simply grab Life or Energy shield, get Champion of the Cause under Duelist for abit more aura radius or get Elemental Equilibrium if you want (Cast Arc, have Hatred and Added Fire on minions) Some life nodes are close to 1 point 20 strength nodes. Unwavering Stance is very close if you hate stuns that much too.

I'm putting this build to rest at this point because I want to work on my Non-Crit Glacial Hammer character. I have no idea what I would get if I were to level past 90 except maybe more life to counter chaos damage

Melee Physical > Minion Damage > Faster Attacks > Minion Life > Added Fire

Multistrike would cause the zombies to lock in place when using normal attacks, and also doesnt work with their slam. I use faster attacks because the slam is abit slow, but if Flesh Offering is up, then the speed is alright so you can replace it with Added Fire or Minion Speed. I didn't notice a difference when using Increased Area of Effect

Zombie AI requires you to tell them what to attack or they kinda stand around 70% of the time, so you'll need something that let's you direct them to packs or bosses.

(Inside The Baron)
Skeletons/SRS > Minion Damage > Melee Physical > Multistrike

Skeletons let you easily drop them somewhere and have your zombies run to that spot. SRS are more for if you just want to hold right click and let your minions do their own thing. Both work but offer different styles. Multistrike is used here because it doesn't matter if these minions are locked in place since they are used just to direct the zombies and extra single target

If using Doon Cuebiyari
Arc/Ball Lightning > Curse on Hit > Elemental Weakness/Enfeeble/Temp Chains

Lightning skills to activate EE then using added fire and/or hatred on your zombies for extra damage. The Curse on Hit is just extra damage or to help your zombies live longer during sketchy map mods

These are based on personal preferences
Hatred for more Damage
Haste for quicker clear
Vitality for longer living zombies
Purity of Elements if you aren't elemental capped or for heavy elemental damage maps
Clarity so you can quickly summon skeletons/SRS

Convocation for easy zombie grouping
Desecrate
Flesh Offering > Increased Duration should be up 100% of the time
Spectre of your choice
