Traits and Flaws are special things that you can choose at the beginning of creating a character that gives your character flair. Traits are a specialization of sorts, granting you boosts in certain skills that give you an edge in those certain areas. Flaws grant you more points at the cost of certain aspects involving your role play. For example, if you have a flaw such as a fear of Rancor, this grants you say 15 extra points but every time you come against a rancor you have to roll morale to not just shit your pants and run away in fear. Extra points, for flaws, simple easy and understood.
