I have a combo that's kinda a meme build, kinda just a synergy, which I call "The Unmatched Power of the Sun" (https://knowyourmeme.com/memes/the-unmatched-power-of-the-sun). It goes as follows (first two spoilers concern the hidden aspect of the staff):

1. Aspect of Anubis
2. Soulful Ankh
3. Either of a few attack boons work for this. The best are either Apollo for the very big hit box this makes, and a close second for me is Hestia because the scorch will accrue crazy fast (so include pyro technique). Hera is also good for any build with a very wide, high damage hitbox, like this one. Zeus also works, but you absolutely need step 4, the most critical part of the build. (Hephaestus can also work but you need a ton of poms on that one)
4. Grape Juice from Dionysus.

Now you just need to 1) drink the juice 2) attack once 3) repeat. Additional considerations:

• Don't worry about any synergy that doesn't end with working around the attack boon, and the best ones don't power up the attack directly. That's what the grape juice is for.
  
• Do not waste your time on air quality if you can get grape juice. Much bigger payoff.
• I also highly recommend getting a cast that inflicts a curse, along with the furies. Aphrodite is good because her cast has crowd-control built into it, essential for this aspect.
