Grape Mentats (1)



  • 3 can be found in Hubris Comics: one on the third floor on a desk, and two in a suitcase in the changing room on the top floor.
  • 3 can be found in the underground levels of Listening Post Bravo (accessible during the quest Blind Betrayal): one on a console on the western wall of the first room, and two more on a table right before Paladin Danse.


  • With their +5 CHA, Grape Mentats can give even the least-Charismatic characters a shot at passing difficult persuasive dialogue options.
  • Because Charisma in Fallout 4 affects buying and selling prices as well, the bonus provided by consuming Grape Mentats can be immense when paired up with their natural +10% boost. However, there is a limit to how much a price can be influenced at a vendor, and no amount of additional Charisma or Grape Mentats will drop or raise the price beyond that limit.
  • Grape Mentats can also be used by the Sole Survivor to increase the number of settlers in their settlements that have already reached their maximum settler capacity.
