The Minor Ability score is a decimal value ranging between 00 and 99. Your character will have a minor ability score for each of the 4 abilities (Strength, Dexterity, Intelligence & Wisdom).
Your character starts the game with a score of 00 for each minor ability score.
Each turn your character will obtain a number of ‘Minor Ability Points’ that can be distributed as you see fit amongst your character’s 4 minor ability scores.
The minor ability score cannot exceed beyond 99, though it does have a bearing on any and all Criterial or Fumble rolls.
