Trait

In the SPECIAL character system, Traits are optional character modifictions that affect the player character. Traits modify different aspects of gameplay, including (but not limited to): Main Statistics, Derived Statistics and Skills. Traits always have both positive and negative results. Fallout 3 is the first SPECIAL game where there are no traits, as they were rolled into Perks. In games where Traits exist, one can choose up to two traits when designing a character (the player might also choose no trait at all). Choosing the Mutate! perk lets the player change one of his traits. Note that if you chose no trait at character creation, you cannot fill the empty slot with this perk.

In Fallout Tactics, where characters of different races can be created, traits also have different racial requirements. In Lionheart, a fantasy game which used the SPECIAL system, a different approach to racial traits was chosen. For each race one was free to choose (or not) any of the regular list of traits, but if the character belonged to one of the "tainted" races (i.e. everyone except pureblood humans), the player had to choose one of the list of racial traits available to their race. These traits were the only thing that distinguished the races from humans, and often had no penalty other than marking the character as tainted.
