Third Edition also added an additional character attribute, Experience, not unlike a role-playing game to help the character develop their powers. By defeating enemies (hostile monsters, but not other player characters), the characters accrue experience points. The experience they gain is equal to the defeated enemies' craft or strength. These experience points can then be redeemed for gold, strength, craft or life at the cost of seven experience points for one. The earlier editions used a similar, but more limited feature which applied to strength.
