Hard agree that explode totems is the way this league. I also tried Shockwave Totems, and good clear and 80M pinnacle damage isn't too hard to reach.
OP. Lots of build guides out there for explode totems. You can start with Ziz who is a pretty reliable creator: Ziz Explode Totems Guide
And poe.ninja of course. Just look for Pathfinder -> Devouring Totem builds for inspiration.
You got a snort out of me with this one. Nice.
