“Your prefrontal cortex has been enhanced with the Empathy Synthesizer, increasing your Charisma by 1.”— In-game description
Charisma Implant is a Fallout: New Vegas perk.
Effects
This implant can be bought from Doctor Usanagi at the New Vegas medical clinic for 4000 caps. It increases your Charisma by one.
Notes
Charisma is a stat that is easily bumped up to meet any requirement since many different armors and the stacking effects of alcohol give temporary bonuses to Charisma.
