Under the Collar

Under the Collar is a radiant side quest in the Fallout 4 add-on Nuka-World.

Detailed walkthrough
Upon acquiring the quest and travelling back to the Commonwealth, the player needs to locate the target. There are two options available for collaring them: stealth or brute force. Since the person in question is usually found in the company of others, be it civilians in cities or raiders/Gunners with their respective squads, sneaking up on them can be very difficult. If stealth is not an option, beating the target into submission in unarmed combat provides a foolproof, though potentially dangerous alternative. If the target is friendly and the player has invested in charisma, the target can be convinced to follow the player to a less visible location where they can be collared non-violently through a second charisma check. As soon as the Shock collar has been put around the victim's neck, they will run off and disappear from the game the moment they leave the current cell. Returning to the quest giver to collect the reward finishes the quest.
