My plan was to swap to Prowess every time before I used an action boost, and then back to Nystul's; since Prowess is sustained outside of the sentient weapon, it'd be almost identical, but with the increased MRR cap. If I find that I'm getting crit at all by mobs that are not Beast Mark/Infernal Pact/etc, I'll just go back to Legendary Disciple of the Dawn with a Ghostbane augment; no harm no foul there. I'd lose 5 Hide and Endless Night doing this, but that's negligible compared to an otherwise loss of practicality. Echo of Ravenkind is something I may very well eventually incorporate, though it appears to be bugged in several ways atm. I currently run Legendary Flightfoot Greaves on my aasimar (saves me blinding speed and grants FoM), but that wouldn't solve the dodge problem if some other gear were shuffled. I'm in too much of a farming mindset to think too heavily about gear atm - amber temple is life I'll reply back with my thoughts whenever I eventually decide to throw things around again. Going to take a lot of these things into account and see how they ultimately fair versus the setup I've been currently running.
As a side note, I'm relatively certain that I'll have reaper wings in at least 4-5 days, gonna keep endlessly grinding
