Charm
From NsdWiki
Charm is the measure of a character's likability — how well he or she can carouse with the best of them.
Charm 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 Charm score is a real drag: unlikable, bashful, boring, or annoying. Characters with a good Charm score are the life of the party: amicable, sociable, and guiding.
Those with great charm: sterling conversationalists, JFK, and Hugh Hefner.
