I looked up a few and i think you can see the Ability Scores in BG3 Wiki. At least of some of them.
This gave me pause. The ability scores of some NPCs are way over the top. Look up kahga or better, examine Gekh. Even if those are NPCs they should at least be somewhere near the possiblities the Races give. Having a lvl 5 Duergar with 18,18,16,14,14,12 or something like that would make him some kind of uber Dwarf.
Kagha is nearly the same.
While i do not think the battles too hard it still feels like an unfair advantage. I downloaded some mods to go that way and the battles got ridicoulously easy. I always hated having a games difficulty based sorely on enemy strenght. Nothing tactical about that.
That does seem out of the ordinary but again you have to realize NPCs are not player characters. They do not have the limitations players do, but that particular Duergar is stronger than a CR 6 Duergar in official books. They have the same Strength score but overall that "Level 5" Duergar is way tougher than his "Level" expresses.
Something I recall Larian saying that they had to go with "Levels" of monsters instead of Challenge Rating to simplify it. Maybe I was wrong earlier, Larian really does expect you to cheese strat some of these things.
