Skills are abilities that a player can learn and use to perform a particular action. These abilities are unique to a particular class, and are also retained even when a player starts a New Game Plus. Players can learn multiple skills from different classes. There is a definite, but very huge amount of skill-mixing possibilities that a player can have. Regardless of its purpose in combat, skills are essential in a character's development in the game, and a proper knowledge of how a skill should be used is required to master the different challenges in the game.
Skills can be learned by visiting a Skill Trainer corresponding to the class that a player wishes to learn, which is located on towns throughout Haggerdom. Skills require a certain amount of attributes as well as costing gold to be learned.
