The effect of frightened status is different.
Frightened status (RAW):
A frightened creature has disadvantage on Ability Checks and Attack rolls while the source of its fear is within line of sight.
The creature can’t willingly move closer to the source of its fear.
I believe BG3 forces frightened creatures run away and prevent them from using any action. (If they didn't change it recently.)
Oh I see, yeah ok that makes sense. The status debuff Frightened - which doesn't specifically say it forces you to run away - assumes you would run which of course opens you up for AOO. They are literally using the spell Fear - which does force you to flee instead of just the debuff.
On balance I could see how they could imply that, and it does affect us the same way.
