Charisma

In gaming, Charisma is a stat often used to determine how likable you are to NPCs, and can play a part both in unlocking otherwise-hidden dialogue options, or reducing the price needing to be paid for items.

In the Dungeons and Dragons rulesets, Charisma is the primary stat of the Sorcerer class, and is used both to calculate damage as well as the spells that the Sorcerer is able to cast.
