In Just One Line attributes are a core mechanic of the game. Each of them relates to main features of your character: power, wit and cunning.
Every faction and race is related to a specific attribute based on their natural inclination. However, you are not bound to that specific attribute and you can boost whatever attribute you want thanks to items and drinks.
While questing, your attributes will be put to the test in many situations you face. Every challange, encounter, dialogue and story interaction will require a minimum score of power, wit or cunning (depending on what you are trying to do) in order to succeed.
