All abilities used in the game are associated with a Target Number, a numerical value that the roll result must match or beat.
Most rolls made by the Player heroes are made against three Attribute Target Numbers (Attribute TNs, for short), based on the ratings they have in Strength, Heart, and Wits.
During character creation, the players generate three Target Numbers, one for each Attribute, putting a hero’s fundamental capabilities right in front of a player’s eyes.
Each Attribute TN is equal to 20 minus its corresponding Attribute score.
