"since BG3 is not even going to reach levels where casting WISH would be a thing."
What?? Gosh, I sure do wish we could eventually get to those levels. Boy, if there is one thing I could wish for, it would be to try out those pinnacle 9th level spells. Maybe it is just wishful thinking on my part, but I think even a limited wish would be worth implementing, but only if Larian wishes to believe so.
