Experience points Edit
Experience points are generally awarded for the completion of quests, overcoming obstacles and opponents, and for successful role-playing.Experience points are used to improve characters in discrete experience levels. As the difficulty of the challenge increases, the experience rewarded for overcoming it also increases. As players gain more experience points, the amount of experience needed to gain new abilities typically increases. Alternatively, games keep the amount of experience points per level constant, but progressively lower the experience gained for the same tasks as the character's level increases.
