There's certainly been discussion of it on the discord (like a thread on it)
All I can say for Devour the Rich is that there are some other mechanics that interact with it
I'd say more but for superbosses I really do try to hold my tongue since they're the big challenge of the game.
(edit: Also, you'll get some more tools going forward if you continue to play and come back to it, ones that'll help)
Particularly that mechanic tends to be easier with more tools since there's just more ways to do the thing via different Accessories you pick up over time.
Oh, and its designed to force a three person party and tier 1 classes. So the only way you can get stronger against it is more tools on the toolkit
