The Scale of Modifiers

A character's Characteristic or Skill modifier determines how good or capable the character is at that task or quality. Likewise, the Difficulty score of a task indicates what degree of challenge it presents to anyone attempting to carry it out. You and your GM should use this table and the examples of Difficulty scores specified elsewhere in Potestas when assigning the Difficulty score for any particular task.
