Phoropter as a settlement object
|Leads to: Lady Luck|
Valery Barstow next complains that the Hippocratic Oath is backwards and that doctors should focus on the greater good of the Vault, rather than patients' welfare. She requests you to build a phoropter prototype, which must be powered and programmed as per the previous objects.
The three parameters involved are Subliminal Messaging, Vault Monitoring, and Improved Eye Care. Most companions will hate the negative parameters and like the positive one.
If you chose mostly negative experiments for the three projects, the 'patient' will become angry and leave the vault. Trying two positives and switching to negative for this one will result in a speech check to convince them to stay.
After completing the quest, the phoropter can be mass produced. It's located on the Vault tab under Resources, while on workshop mode. The stats of the device depend on the experiment option that was chosen.
- Selecting the subliminal messaging experiment option makes the device provide 15 points of happiness for 6 units of power, at the risk of killing random non-essential settler (2% chance per day).
- The Vault monitoring option provides 5 points of happiness for 3 units of power, and can also kill settler (1% chance per day).
- The improved eye care option provides 10 points of happiness for 3 units of power, without any risk of death.
Curie "loves" if, when asked by the overseer about the hippocratic oath, the Sole Survivor says it is "there for a reason."
