Perk（輔助能力、特長）是玩家角色在SPECIAL系統中能夠獲得的額外能力。 The number of ranks each perk has determines how many times the perk can be obtained.與同時帶來優缺點的Trait（特徵）不同，Perk帶給玩家角色的幾乎只有好處。
Type of perks编辑
Perks obtained by special actions or interactions with other characters.
Perks obtained as a reward for quests.
These are perks obtained through implants by an Auto-Doc, which cost money. In Fallout: New Vegas, the number of original implant perks (not those of Old World Blues) you can receive is equal to the player character's Endurance statistic.
Perks obtained as a reward for challenges.
Perks adding special unarmed moves.
Perks which are obtainable by having a good relationship with the respective companions. Companion perks are disabled when not traveling with the respective companions.
Unique companion perks编辑
Perks of a companion, affecting only them.
A character's perk rate determines how often the player character gets to choose a new perk (or an additional level for an already obtained one). In Fallout, Fallout 2 and Fallout Tactics, the player character can choose a perk every three levels, with Fallout Tactics offering different rates for non-human characters. When choosing the Skilled trait, the perk rate is reduced so that the player character can choose a perk every four levels. In Fallout 3, Fallout 4 and Fallout: Brotherhood of Steel, the player character gets to choose a perk (or skill) at every level. In Fallout: New Vegas, the perk rate is set at every 2 levels.
