Developers need to be warned about this at the stage of character creation. If intelligence is below 8, then the main character becomes a fool. Many dialogues are inaccessible to him, others look at him with pitiful sympathy.
But such a player will have a unique romance with the Goblin Sazza, who will become his wiser partner, mentor in this cruel world. And a unique ability to dialogue with the most stupid of monsters and humanoids. Oh, it's like the Trickster's way in Wrath of the Righteous.
Not for me... but why not if someone really wants to play like that
