How to increase DPS as a BAMA necro?

Hey everyone,

This is my first time playing BAMA this league, and I’m completely new to both minion builds and the Necromancer ascendancy.

Right now, I’m stuck at around 2.5 million DPS with a setup that seems almost identical to the one I'm following (Ronarray’s build)
Here’s the video that inspired me: https://www.youtube.com/watch?v=fv_ifkdhFLc&t=160s

I feel like I’ve got all the key components in place, but I'm still sitting at about 2.5 million DPS, while Ronarray is showing 50 million in his PoB.

Ronarray’s PoB: https://pobb.in/dOpKjf4b1oRu
My PoB: https://pobb.in/7pQHQLAgpgUS

Does anyone know what makes the difference between these two PoBs?
Is there some key interaction or mechanic I might be missing?

Note: I haven’t factored Shock into my PoB, but even with that added, I’m still light-years away from hitting 50 million DPS.

Thanks in advance to anyone who takes the time to help me out.

Have fun!
