CI BV Zoo summoner (3.4, WIP)

Using culling strike and poison support on Blade Vortex, both Herald of Purity and Herald of Agony minions can be maintained. Since Blade Vortex has a duration, Skeletons can be cast while at max stacks as extra damage, with Zombies being a constant meat shield and slight additional damage.

Energy Shield is used due to having an ES chestpiece and helm. While a life based version is likely possible, and I may make one at some point, I found that achieving reasonable levels of ES was much easier.

Guardian is taken due to the minion buffs it gives via Minion Accuracy, Sentinels buffs, and intimidate. Radiant faith is also a significant amount of ES, allowing us to avoid going a life based build.

Shield charge is used as the mobility skill due to having an unusually high attack speed for casters from Spiritual Command.

Use skeletons to get bodies to raise as zombies, then buff yourself with BV and shield charge around the map, using any downtime to summon more skeletons.

Body armor:
This build requires The Coming Calamity unique armor, in order to support herald minions without running out of mana. There's simply no choice here.

Helmet:
Look for a +2 minion helm at least with good resistances. If possible, the elder mods giving extra minion support links are extremely strong.

Gloves:
Focus on finding strong energy shield and resistances. There are no offensive mods worth taking.

Boots:
Movement speed and dexterity are the priority on these, with resistances and ES being secondary.

Amulet:
Strength and dexterity are necessary as an implicit if nothing else. Besides that, resistances and ES as always. An alternative is the new unique Perquil's Toe, if you're able to fit this into the resists and stat budget.

Belt:
This is the main source of strength, so make sure to grab a heavy belt with strength as a suffix. Alternatively, an stygian belt with strength would work.

Rings:
Several choices here. Essence worm is a not too expensive unique which works well, as it allows us to run an aura. For a cheaper option, the new Mark of Submission with Temporal Chains is a significant amount of defense. On the expensive end, an The Hungry Loop is extremely strong. Regardless of your choice, one ring should be a rare with ES, dexterity, and resistances.

Shield:
A standard ES shield with resistances and/or block is the best choice here, to help with the build defenses.

Weapon:
The choice here is looking for defense or QoL. Heartbreaker is the best choice for QoL here, without losing out on too much ES. For maximum ES, Ephemeral Edge is the best choice. An alternative to Ephemeral Edge is a mana/ES The Dark Seer, as it gives almost as much ES as Edge and also provides a chance to blind, which can be useful.

Jewels:
Energy from Within jewels at the sockets north and east of the Witch provide significant ES, and an abyss jewel with the mod "Minions have X% chance to taunt on hit" adds significant survivability.

This is what the build is designed around, as most people do not achieve 6-links.

If you have an essence ring, run Haste for faster clear, or Determination for more defense.

If you have The Hungry Loop, put your skeletons in it with brutality, move your Herald of Agony into your helm, move zombies to your gloves with brutality, and add in a CWDT-Immortal Call-Increased Duration to your shield.

If you have the Minion Damage Support elder mod in your helm, add in Brutality to skeletons, or GMP to your Herald of Agony.

If you have Heartbreaker, remove Culling Strike and add in either Increased Duration or Less Poison support to your Blade Vortex.
