Difference between slightly weaker enemies and core?

[Schwarzhelm]

I am playing with a suboptimal build so I reduced the enemy difficulty to slightly weaker, crit and damage are not reduced.
Now my dumb question, what is the difference? I am right now at the vescavor queen and her stats seem to be the same. Looking into it I found a screenshot in the steam forum where the difficulties are compared and imo it looks like slightly weaker is the same as core (no changes).

I noticed that the vescavor swarms did not trigger their gibber ability even though it is still in their description but this could have been a bug on my side since the queen still had it.

It remains a mystery.

I discussed it here (the screenshot you saw was probably from me).

Enemy stat adjustments (difficulty) seems bugged

I have been doing many tests since yesterday to compare difficulty differences. Under Enemy stat adjustments, “Slightly weaker” is consistently giving me the same exact enemy stats as “Standard [none]” (so Daring and Core result in exactly the same HP, AC, Ability points, Saving Throws, To Hit). I do not know if this is a bug, but other choices such as Moderately weaker (Normal) or Slightly stronger (Hard) causes a significant difference in stats, so Slightly weaker (Daring) being identical to…

Ps: personally, I always reduce the Crit damage, because they are often one-shot kills in PF1. The reduced version remains plenty of damage but without being over the top.
