3.13 Caustic Ground Zombie Consumer

Level as you would any normal minion build. You will initially want to map with spectres or normal mon'tregul zombies as this build struggles to operate without a 6-link. Tab is fine - this league I used tab clearing T16s and level 93. Kill all bandits, we need the points!

- please note, PoB currently doesn't support the increased corpse life nodes, but they do affect your zombies with Aukuna's will. I have put it as 80% increased minion life (corpse pact, 2x corpse life nodes) on the large cluster jewel. Obviously this won't affect minions other than zombies but we aren't using them for dps so it doesn't matter.
- PoB is set as if fighting Sirus with Vaal Summon Skeletons up. Endurance charges set to 1 as you often have three up, but not always, so 1 for a rough average estimate.

These are my current gems. Note that if you are not using Kitava's Teachings and/or Bubonic Trail you will need to remove 'Death Attunement', spec to 'Thunderous Salvos' and use unleash to get reliable caustic ground. Or use another means to trigger zombie limit.

My Current Gear:

Essential:
Mon'Tregul, Aukuna's Will, Siegebreaker

Advised:
-6-link chest with a Deafening Essence of Fear applied. Bloodbond is also fine, if you happen to find a cheap 6-linked version of it.
-Two unset rings (1 is fine, 2 is a luxury)
-a sceptre with %minion damage and trigger spells Trigger is just really nice to have. Not essential.
-Elder helm with Minion life Just helps to keep your utility minions invincible. If you get a super juicy one with +minion levels, 20 minion damage and 20 minion life, by god put your zombies in there ASAP.
-amulet with minion damage is BiS, as you can get other mods on it too. Otherwise Jinxed Juju or Sidhebreath are both alright. Anoint with Righteous Army.
-Rumi's, Kiara's flasks Rumi's gives us some much needed block, Kiara's takes care of providing onslaught while giving us ailment and stun immunity.

Jewels with a mixture of life, minion damage, cast speed and minion life, as you require. - cast speed is less important with Aukuna's, but still nice to have

If you can get hold of a Legion jewel that gives you some strategically placed minion life or damage notables, then do it.

Cast raise zombie on a pack, move/leap slam/cast more, zombie dies, everything else dies. Several ways to force-die the zombie in play: Volatile dead on CWDT (no damage, just corpse removal), Bone offering on trigger/CWDT (your preference), Death Walk from bubonic trail kills a corpse with each step, Kitava's teachings absorbs a corpse once per second, and casting 4 zombies kills the first. This all results in near-total corpse removal.

Spectres you have you have a few choices. I run They of Tul (despite nerf they're still good), Arena Masters (move, attack and cast speed, everything we need), and a bubble spectre. You may find, however, that you want to rip your ears off after a while of running with ToT and AM... they're noisy little buggers.

Chaos golem for phys reduction. AG geared with Leer cast for damage, Ambus for endurance charges, Dying breath for damage, Victarios boots for movement.

Despair I like to run on trigger as we only really need it for bosses, but you can run a Witchfire Brew if you prefer.

Skeletons are just there for bosses/area defence mechanics like ritual/blight. They wither everything and provide FF for more damage to zombies. With withering touch on Skeletons, vs a boss you have near-permanent 15 wither stacks as you have ~40 skeletons attacking ~1.6 times per second. (40x0.25x1.6 = 16) At worst you have 9 skeletons doing so while VSS is on cooldown, so you only get ~4 withers, which you can buff up a bit to 9 with withering step. Either way, better than standing around casting it manually or missing out on FF by using a spell totem.

Lunaris and Shakari - helps deal with physical and chaos damage, as well as projectiles and poison.
