The player has to add a sum of the character's Attribute level plus Skill Adds and Specialization Adds bonuses and subtract the Difficulty Modifier (DM) number. The harder the task, the higher the DM number. A DM 3 is a very easy task, a DM 9 is an average task, and a DM 22 would be an almost impossible task. Trying to perform a task or action that requires a rating in a Trained skill that the character does not have does so at an additional DM +8 (more if it requires a Facet or Specialty). Then 2d10 are rolled and the results checked on a modifier table, with the result being added or subtracted from the base sum. The larger the success margin, the greater the result; this is converted into Result Points, which are read on another table to determine the result.
