Notes

You can find the full and very detailed written guide here https://maxroll.gg/poe/build-guides/chaos-minion-army-necromancer-league-starter

Use convening wand otherwise check the convoking wand tree setup


Make sure to have a 4s trigger wand before putting molten shell in it

You will never have the plaguebringer buff on boss fights if you have desecrate in the trigger wand, flesh offering will destroy all corpses.

Helmet implicit can be "minions have increased maximum life" instead of despair curse effect if you want tankier minions.

Ring suffix can be minion life instead of minion movement speed if you want tankier minions.

Hungry loop options
Use awakened AoE if you are using gravebind exploding AG setup, 
Use Awakened melee splash if you are using asenath double curse setup.
Use empower if you just want to make your AG even tankier.
