Here is the final upgrade for my Summon Reaper Champion and a dangerous ~90% quant Uber Eater kill to celebrate. I was sitting at ~31m bleed dps in my last video. Beeing that close to dot cap was rubbing me the wrong way.

Here is how I achieved dot cap:
I didn't want to pay 300 divs for Awakened Empower, so that was a no-go. I also didn't want to replace Asenath or Anathema to achieve a "fake" dot cap. I tried hitting Eldritch Battery with tattoos and was prepping for a +2 helmet, but I hit Lethe Shade first, so I settled.
Final solution, and probably the cheapest: Buy a corrupted Diadem with "90% Cost and Reservation Multiplier" (30divs), get a lab service for Reaper enchant (7divs), add a small cluster with reservation. Use the free mana to add Flesh and Stone and replace the "weaker" maim support from Skeletons. Then shift some gear back towards "increased dot damage taken when maimed by you" and voila, dot cap.
This version can also run a Mageblood now while still maxing out Anamamu.
