Menagerie build help

Alright. I am a complete n00b who has just about 100 hours in the game. I am starting my second build, and I want to go for a full on menagerie build where I have all the minions that do all the damage. The objective is MASS. I wish to live out the gaming fantasy of having a huge army. Rn I’m running a necro / occultist because I saw occultist has minions.

My questions are

1. Best class combo to summon all the minions?
2. How the heck do I scale the damage so my army can effectively deal damage?
3. What skill or thing should I be spamming in the fight?
4. Theoretically, what are some ideas to turn this from a normal menagerie build to a funny one? Darker the humor the better
