Every character has a finite set of skills he or she can learn during the course of the game. Each known skill has a level score, representing the character's proficiency in that skill. The skill level can be raised by spending ADV Points on the Character Screen. The ADV Point cost to train a particular skill is determined in part by the character's class.
