I'm not sure why are we even discussing the absolute powers. they have nothing to do with the evil path. they are a completely separate storyline, and you can complete EA (in both paths) with or without them.

Larian's Biggest Oversight, what to do about it, and My personal review of BG3 EA
"74.85% of you stood with the Tieflings, and 25.15% of you sided with Minthara. Good outweighs evil, it seems."
