Location: Novigrad Docks
Go to the Novigrad docks, once there you’ll notice a woman being threatened by a hooded man. Speak to the woman and she will tell you that she can handle herself. You can either use your Axii sign (Level 2) on the hooded man, threaten him normally, or leave as the woman said. Any option you choose ends up revealing that the man was acting with the strumpet and you killed his mood, the prostitute ends up not getting paid.
