Experience Points (XP): As a character overcomes challenges, defeats monsters, and completes quests, he gains experience points. These points accumulate over time, and when they reach or surpass a specific value, the character gains a level.

Playtest Idea: Each character who participates in an encounter or challenge will earn XP equal to the challenge rating of the monster or trap; or equal to the level of the adventure for non-combat encounters and puzzles. For information on how this would interact with class levels see character advancement.
