Charisma is a stat gained by eating fruit and vegetables. Both fruit and vegetables, when eaten, increase the charisma of the character by +1. Charisma is used to determine purchases made on the market. If two players place a bid on the market at the same time, the player with the highest charisma makes the purchase. The same method is used when applying for a posted job and when selling items on the market.
Charisma has three associated trophies that are earned by increasing a character's charisma to 20, 100, and 255. These trophies are called Charmer, Leader, and Hero, respectively.
