Traits

Traits are optional modifications that affect the Player Characters. Traits mostly modify aspects of gameplay, such as primary attributes, derived statistics, and skills, but can modify story elements as well. Traits have positive and negative effects, unlike perks. Player Characters may choose up to two traits, or even none at all before they start their campaign. Whenever a Player Character mutates, they change into two possible races, Super Mutant or Ghoul, and are allowed to choose new traits, including their racial traits.
