Duo Aurabot Guide/Build

Wanted to move this discussion here since I found it an interesting topic.

Big thanks to Sunshinetroughrain on Reddit for the link and comment:

Haloplasm is the best source by far https://youtu.be/2p4v2lwXfqQ

I haven't tried duoing outside of running independent builds and just playing together. I'd be interested to hear from people who run group content. It's always fascinated me but I haven't tried anything but the solo playstyle.
