This Golden Ring

This Golden Ring is an overseer quest and part of The Book of Wuv multi-stage questline in Fallout Shelter.

Walkthrough
Enter the five-floor building, and head down the elevator and clear the two rooms underneath. You may encounter radroaches, mole rats, and feral ghouls on this quest.

Around the first or second floor up from the ground floor is a group of feral ghouls, which prompts a dialogue choice. Selecting "I don't want your “prize,” whatever it is. I'm looking for gold" will prompt the ghouls to give the party a single bottle of Nuka-Cola Quantum, otherwise a fight will ensue.

At or near the top floor of the building, there are two feral ghouls and a glowing one. Defeating them will result in locating the gold watch (the something gold) and completes the quest. The room they are in contains an additional bottle of Nuka-Cola Quantum.

Behind the scenes
The quest's name is a reference to the One Ring from The Lord of the Rings. The ghoul's dialogue shares similarities with that of the character Gollum.
