Arcana
Night (X) is THE
Aspect of Momus Arcana Card. Never run Momus staff without it. Even at max rank, the Ω Move Pulses last 4 seconds each. Meaning you always have time to get one or two different Ω Moves out in each cycle.
- Should mention that ONLY the first Omega Move of each benefits from
Night (X). The two follow up Bursts will not deal Crit from
Night (X).
Eternity (IV) will help with your ability to reactively dodge cancel your Ω Move channeling. When using
Jeweled Pom start, its very easy to allocate 3 Grasp to this Arcana, so I'd recommend using it.
Eternity (IV) does not slow down IGT, so if you're having trouble with
Vow of Time, I recommend NOT using it.
Keepsakes
Jeweled Pom is King in post-credits runs, so of course using a Fates' Whim loadout is very good.
Specifically for
Aspect of Momus, I also like starting with either
Harmonic Photon,
Iridescent Fan, or
Barley Sheaf. Each of these three Gods have great synergy with Momus Staff.
Demeter is my personal favorite because Freeze will make it easy to Channel Ω Moves, and
Weed Killer +
Local Climate massively boos your Ω damage.
Familiar
Hecuba is good for taking away any worry about Magick limitations.
If feel you need defensive sustain,
Toula,
Frinos, and
Gale are each good depending on preference.
Raki is best for damage and speed, because even a 4% Crit chance over the cource of a run adds a lot of damage to the high numbers of your Omega Moves.
Oath, Vow, Fear
The hardest Vows specifically for
Aspect of Momus imo, are
Vow of Frenzy 2 and
Vow of Pain 2 & 3. It can be quite challenging to not get hit a lot while channeling Ω Moves so often, and
Vow of Frenzy makes it extra challenging. You can run
Eternity (IV) to help offset the increased enemy speed.
Vow of Wards means your initial Ω Moves deal no damage, but since the pulses repeat, its not overly punishing to have activated. It will slow down your pace quite a lot, however, because you won't be killing on spawn.
Vow of Hubris can really screw you over as well and prime you out of Magick.
Other than these, the standard rules apply for how challenging the different Vows are. You can find a more in depth breakdown of Fear here
