Perks & flaws are special effects that can be applied on a character, and that are always active. Perks are positive effects and flaws are negative effects. Each class begins with 1 perk and 1 flaw that are characteristic of that class. Later, as the class levels up, more slots open up and it is possible to add more perks & flaws (up to 4 each) or change any perk or flaw for another that has been unlocked (by unlocking another class). For each perk added, a flaw must be added as well.
