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 peoples' vices to increase productivity. Valery Barstow wants to focus on greed, and as such has a prototype Slot Machine for you 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. You can choose from: Indentured Servitude, Customer Profiling, and Lost Revenue. Again, choosing negative parameters will lose respect from your companions.

After Clem has gambled for an hour, Barstow will approach and analyze the results. Depending on your choices on the previous experiments, she will either approve, state there were mixed results, or disapprove. She will then state that she wishes to venture out into the world and conduct experiments elsewhere. There is an orange dialogue option to make her stay in the vault.
