Overview
Rough Neighborhood is a secondary quest in The Witcher 3: Wild Hunt, set just north of Shani’s clinic and southeast of the Western Gate on the edge of Oxenfurt. It appears at night after the drinking part of Contract: The Oxenfurt Drunk, and disappears if you wander off. The XP drops after level 22.
Dora
Three mercenaries are harassing a woman. Whatever Geralt says, it becomes a fistfight, and losing counts as death. Drawing a sword and killing them makes her run off and ends the quest without reward.
Once they are down, Dora says she could have handled them herself but thanks him anyway. Geralt can walk her home, which she accepts after making it clear it will not lead anywhere, or just say goodbye.
Round two
Later, five mercenaries are waiting in the courtyard southeast of the Western Gate signpost. If Geralt walked Dora home, she is standing nearby and jumps into the fight. Otherwise he faces them alone.
