Each character has 5 basic traits: Endurance, Fortune, Psyche, Strength, and Warfare. Each character also has 3 derived traits: Presence, which is the higher of Fortune or Psyche; Stamina, which is the higher of Endurance or Strength; and Power, which is the highest of Endurance or Psyche or Strength or Warfare. The 5 basic traits are set individually, and range from -2 to 4. The 3 derived traits range from -2 to 3; if a basic trait is 4, any derived trait it affects is still capped at 3.
At character creation, assign values to each basic trait, from -2 to 2, assigning a value of 2 to no more than 2 basic traits. If 2 basic traits have values of 2, then all 5 basic traits should add up to 2. If 1 or no basic traits have values of 2, then all 5 basic traits should add up to 3.
Experience checks will usually come from rolling traits. There are 5 options for doing so, 2 of which will be highlighted during a session.
Endurance & Stamina
Fortune & Presence
Psyche
Strength
Warfare
At the beginning of each session, the player of a supernal picks one, and then the MC picks one.
The advances available to characters will depend on the setting. A game set in Amber or the equivalent will have one set of advances, and a game set in the mythic past with players as heroes will have another.
