Charm
From NsdWiki
Personality is the measure of a character's likability — how well he or she can carouse with the best of them.
Personality helps with getting to know people, making good impressions, seducing the king's daughter, and communicating effectively. It can be used to lead others: both people and animals.
A character with a poor Personality score is a real drag: unlikable, bashful, boring, or annoying. Characters with a good Personality score are the life of the party: amicable, sociable, and guiding.
Those with great personality: sterling conversationalists, JFK, and Hugh Hefner.
