When you master charm and you kinda max out the "comfort", you get a third option on the Dark Path in the middle of the forest. Am I missing a step, though?
I think you're referring to the characters acceptance level for comfort.
Dark path in the forest has a couple possibilities.
If it's your first time there and you haven't beaten the boss yet, then you'll get a scene with an owl dropping a ring.
If you already saw the scene with the owl, then it's a generic scene.
And lastly there's another option. If you return there after dreaming about a girl, there will be a scene where you can save a girl that's tied up.
In this scene you will have a few options. If you know illusion magic, you can use an illusion, if you know fire you can cast fire. And if your acceptance is high enough (most players probably don't see this option), you can charm the bandits.
