Charisma

Cost: [5/level] (see Charismatic for the Ultra-Lite version)

Charisma is a mental, mundane advantage representing the natural ability to impress and lead others.

As an Attribute[]

Cost: [±10/level]

Charisma as an attribute has a base of 10 and replaces Charisma and Smooth Operator advantages. Covers at least the following skills:

Acting, Carousing, Detect Lies, Diplomacy, Fast-Talk, FortuneTelling, Intimidation, Leadership, Panhandling, Politics,

Public Speaking, Savoir-Faire, Sex Appeal, and Streetwise.

Adolph Hitler is often said to had Charisma but he wasn't given this advantage in Classic: Who's Who 2. Instead he was given the skills Performance, Psychology, and Public Speaking to simulate Charisma.

Sean Punch has commented on Charisma in the following post to the SJG GURPS Forums:

in 2007
- This falls under the "Charisma clause" for Telepathy on p. 134 of Powers: "Telepaths often have Charisma as a side effect of their power, but it isn't considered one of the power's abilities." That is, you can use "I have this power" to justify "I have this unusual-but-related advantage," but you can't argue that an advantage without the power modifier should benefit from a power's Talent and use whatever power-stunt rules the GM allows. If you want those benefits, then you have to accept that your advantages are shut down with the rest of the power, and give them the power modifier.
  - page 61 of GURPS Psionic Powers has the "Aspect" power based on Charisma, part of the Telepathy "Control" series.

On its cheap price in 2008 ("I'd probably price Charisma at 10-15 points/level, were I starting from scratch.")

Kromm said that Charisma doesn't apply when interacting with animals. Only Animal Friend does.

Need to ID earlier post affirming this.
