Lady Luck

Lady Luck is a quest in the Fallout 4 add-on Vault-Tec Workshop.

Detailed walkthrough
The final experiment focuses on attempting to harness people's vices to increase productivity. Valery Barstow wants to focus on greed, and as such, has a prototype slot machine for the Sole Survivor to build, power, and set parameters.

Because Barstow herself created the prototype, there are no R&D team notes available on each parameter, but instead can be accessed in her notes under the second menu. One can choose from: Indentured Servitude, Customer Profiling, or Lost Revenue to make the resident win every time.

After Clem has gambled for an hour, Barstow will approach and analyze the results. Depending on choices made during the previous experiments, she will be satisfied or mixed on the results. If the Sole Survivor chooses all the "inhumane" experiment perimeters, she will be satisfied with the work and announce her intentions to head out into the wasteland. Choosing a mix of humane and inhumane perimeters will result in the same outcome. Nevertheless, both results will still give the player character the option to convince her to stay in Vault 88 with a speech check. If the Sole Survivor only chooses humane perimeters, she will be dissatisfied and will angrily leave Vault 88, without the ability to convince her to stay.

Regardless of one's decision, she will give the Sole Survivor a unique vault suit, reducing damage from ghouls by 15%, and the quest will end.

After completing the quest, the slot machine can be mass produced. It is located on the Vault tab under Resources, while on workshop mode. The stats of the machine depend on the experiment option that was chosen, although all versions require 1 unit of power regardless of the experiment.
 * Selecting the indentured servitude experiment option makes the machine provide 3 bottlecaps per settler at each settlement reset.
 * The customer profiling option provides 1 bottlecap per settler and 5 points of happiness.
 * The lost revenue option provides 15 points of happiness.
