Experience or Skill Points
Another currency in the game is experience or, in our case, skill points. When players first made their characters, they were given a number of starting skill points to get started. As players complete adventures, dispose of fiends or even just talk to people in your world, make sure to reward them with skill points so that they have a sense of accomplishment and get to experience the thrill of character advancement.
For comparison with other game systems that utilize levels, Untitled assumes that between ten and fifteen skill points is roughly equivalent to a single level. As the Storyteller, you decide how many and when to award skill points, as well as how they are earned in your campaign. You could give a skill point or two to a specific player for exercising good judgement or completing an especially difficult puzzle, or award the entire group at once when they hit a milestone in your adventure.
