I do feel that compared to standard 5e, BG3 has really limited options for unarmed playstyles.
Monk unarmed damage does not increase with level as it does in 5e, Unarmed or Improvised Weapon proficiency simply does not exist so it doesn't scale too well, and as far as I'm aware there are no artefacts that give a boost to unarmed (though throwing and improvised weapon ones do).
I can appreciate that Monk was a late addition to the game, so there may not have been a lot of time to develop around Unarmed as a concept, I'm just hoping in a future update unarmed gets a looking at.
