Cooking is used to prepare raw food to restore health. There are many different types of foods, with each healing a certain amount of health. However, as with all skills, players must reach certain levels to cook a specific food. Cooking and Fishing are very popular skills to raise as they can generate great profit by catching, cooking and selling foods to other players.
