I don't want to Mod BG3, but is there a place to record or see the combat logs? I'd like to see the rolls and information in there because There seems to be a LOT of Critical Misses, which would indicate rolling a 1. If that's the case, I think their D20 random number generator is not seeding correctly or is flat out broken.
Click the little "double arrow" on the right edge of the screen, near the bottom. That will expand the combat log. There are a few threads about this where people have recorded hundreds to thousands of roles to test this: see e.g., https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=717185&page=9
Keep in mind confirmation bias. You probably notice large miss streaks (because you get frustrated) more often than large hit streaks.
