I can only carry over my experience from SotDL, but if one wanted to avoid a flat bonus system and get into diminishing returns on both penalties and bonuses, I think boon/bane is a great way to go.
Last night, we bumped our PCs to 7th level to try out the Master path abilities in our final session and fought a CR 32 monster - monster scaling is different but that’s pretty tough. The spells and abilities are insane but it was still incredibly challenging. My death priest who could teleport adjacent to anyone who goes down in a fight felt really damn clutch.
