Charisma

Charisma (CHR) is an attribute in Wasteland, Wasteland 2 and Fountain of Dreams.

Wasteland
"This attribute lets you know how likeable or persuasive a character is. Although it may seem like a trivial trait. it might well make the difference between life and death as you try to convince someone that you're trustworthy. Charisma also afects how an NPC will react to you when you want to hire him or trade equipment."

Affected skills

 * Confidence
 * Bureaucracy

Wasteland 2
Charisma is a unique attribute that does not directly impact any derived stats, but your party's total Charisma as well as the charisma of individual Rangers will have a real impact out in the world. It's the combined force of a ranger's personality and desirability. People will react more favorably to a Ranger with high charisma, and might talk about things they would have otherwise kept to themselves. It also ties in with several skills such as Barter and the conversation skills.

In game terms, this means that Charisma determines whether some recruits will want to join (some have a minimum total Charisma count the party has to meet), the leadership radius for the Leadership skill, and affects XP rewards:
