 A character's potential reflects a threshold for a character as it journeys through life. Potential acts both as a yardstick that measures the number of a character’s experiences against other characters and identities, as well as a bar that the character cannot surpass without further advancement. This bar represents the upper limit for some of the character’s traits, increasing as the character progresses through events in the fiction. Just like the character's attributes, potential is a whole number, only it cannot be less than one. Potential is directly proportional to the character’s attributes; it is equal to the sum of the values of their attributes divided by five, ignoring the remainder.

 A potential 2 character, for example, has a sum of attribute values ranging from twenty (20) to twenty-nine (29). A character whose attribute values total thirty-seven (37) is a potential 3 character (30 / 10 = 3 remainder 7). The sum of a character's attributes cannot be less than ten, as that would result in their potential being less than 1.
