SKILLS

Skills reflect the experience and expertise characters have picked up along the way, based upon their life experiences. 
Certain skills require specific, often vocational training. These start at -3 (Inept) instead of 0 (Untrained) and are marked with an asterisk, such as Psychology* or Tactics*.
When a character has 1 level in that skill, they advance from -3 (Inept) to +1 (Beginner).
Levels in skills are called Skill Modifiers (or SMods), and players add SMods to dice checks using that skill.
Each skill is associated with an attribute, such as the Barter skill being tied to the Influence attribute or Unarmed Combat skill being tied to the Physicality attribute. Dice checks use both AMods and SMods.
