The fiends of Hell have “hellish” conditions! In a section with the "Cursed Souls" property, your villain character will be able to quickly increase a number of skills (including the mischief skill), move up the career ladder more confidently as a criminal, and also be more successful in seducing other characters with his depravity... This property will also help longer maintain the character's needs for nutrition, hygiene, natural need and vigor, while the needs for communication and leisure will fall faster.
