I've been making mainly minion builds for several leagues now, leveling at least 4 of them to 100 in HC Trade so far during last couple of leagues. I've done Zombies, Spectres (when they were viable) and last league Skeleton Mages. We had fairly major minion changes in the patch notes, and thus I'm going back to Zombies.

Quick reference:

• PoB: https://pastebin.com/Y7zhtLty

• Build is made for generic clearing of fairly juiced content, not really viable or really annoying for harder bosses because your minions will die

• Adjusted for 3.19, Custom Modifiers has 33% reduced attack speed because of minion Frenzy Charge nerf and 10% less damage because of generic minion nerf at gem level ~30, as per patch notes

• 7.2mil DPS against Standard Boss

• 10 000+ ES

• 45 000 Armor

• Aegis Aurora + Max Block & Spell Block with Glancing Blows

• 84% All Resistances with Melding

• Decay Ward for minion survivability

• Can be adjusted for the new Mon'tregul's Grasp if you want explosions, but you will lose trigger weapon and Aggressive on Zombies

• Needs some minion resist rolls on gear, either from weapon, Ghastly Eye Jewel and/or Bone Ring (can use one Bone Ring)

• Only uses items that will be available on HC Trade, so no Empower lvl 5, Mageblood tier stuff or silly rares

• The way I calculate resists needed is: count number of free suffixes (minus the weapon) = 20, count total resist needed to cap = 511, count average roll needed for each suffix: 511 / 20 = 25.5. So capping resists won't be a problem.

• Gloves don't need Vuln corruption, that's from Animate Guardian but PoB can't simulate AG gear correctly, similarly Zombies have 7link with lvl 1 Culling Strike, that's obviously to simulate Kingmaker

• Animate Guardian items in general: Kingmaker, Leer Cast, generic Gloves with Vuln on Hit corruption, defensive Body Armor depending on your budget (Gruthkul's Pelt, Garb of the Ephemeral, Doppelganger's Guise etc.), Windscream boots

• Spectres are Carnage Chieftain (Frenzy Charges), Demon Harpy (from Scourge/Beyond, increased phys damage taken Scream), third can be whatever
