Personality is one of a character's base attributes that affects their ability to retrieve meaningful information from NPCs, through persuasion or other methods. A character's personality also governs their ability to achieve better prices for merchants' goods. It affects how high of disposition NPCs will have as well. A high enough personality also results in NPCs saying things like: "You seem interesting please share your thoughts". Personality governs the Mercantile, Speechcraft, and Illusion skills.
