Social Skills
Regular socialization is performed with Backgrounds, rather than social skills. If you want to ingratiate yourself with others, track down the word on the street, or otherwise perform social legwork, you probably want to use a background like High Society or Barrio. Social skills apply a -1 dicepool penalty when defaulting.
Animal Ken
Dealing with inhuman beasts is a skill in and of itself. Neither lions nor sheep really have any backgrounds, and the Animal Ken skill is used in their place. Animal Ken is used to read the emotions of an animal as well as to calm one down or train it to do stuff. Animal Ken is thus your one-stop-shop for all socialization with dogs, which considering how much less a dog knows than any human or supernatural about important plot points, is not nearly as overpowered as you might think
Specializations: Domestic Animals, Training, Wild Animals, Riding.
Bureaucracy
Managing logistics and patiently untangling skeins of red tape is the focus of this skill. Characters can understand and manipulate laws, navigate management systems, and correctly formulate formal requests. Bureaucracy is of use whether the character is attempting to perform bureaucratic tasks and of equal utility when confronted by the implacable edifice of a Kafkaesque course. It is not unusual for people to resent bureaucracy, because it is annoying. But as anyone who has done logistics under any circumstances can tell you, not having rules, management, and records in place is even worse.
Specializations: Business, Government, Logistics
Empathy
Empathy is our primary means of interpreting the meaning of actions and inactions of other people. It is a trainable sense of how others are feeling given how they look, what they say, and what they do. Empathy is of obvious use to people like lawyers and police, but it is also an important skill for batters in baseball. It is not merely about figuring out whether someone is being truthful when they are talking, but also about determining what someone is about to do in the physical world.
Specializations: Motivation Determination, Detecting Lies, Action Anticipation, Animal Ken
Expression
Expression is the art of entertaining and changing peoples' minds through art. Lots of people think that this can only be accomplished by making movies about gay cowboys eating pudding, but the truth is that any art that provokes the audience to even acknowledge it is on some level influencing the audience.
Specializations: Writing, Dance, Music, Oratory
Intimidation
Intimidation is the art of using fear to get other people to believe or do things desired of them. Intimidation can be explicit ("If you don't do X, I will stab you. In the face.") or implied ("Did you hear that the feds caught Ted for his tax non-payment? He's going to be doing time.") and the threats can be to the target's person, finances, or reputation. And some of the best Intimidation is actually phrased in a manner that implies that some third party will do some thing to the target and the Intimidating character is willing to help the target.
Specializations: Interrogation, Fear Mongering, Skulduggery, Blackmail
Persuasion
Persuasion is the art of manipulating people in such a manner that it isn't immediately obvious that is what you're doing. People who are skilled at Persuasion are essentially good at lying, although many of them get offended if you call it that. They may prefer the term acting or sales.
Specializations: Acting, Insinuation, Fast Talk
Tactics
Tactics is the skill that governs leadership in both the military and corporate sense of the term. Characters can inspire others to give 100% or produce a battle plan. The dragon crawls on its belly, and Tactics dovetails closely with Bureaucracy in the plotting of war, whether genuine or metaphorical. The tactical aspect involves actually maneuvering and the orders necessary to get others to do that - in contrast to the simple appeals to rules or potentially complex logistical management of Bureaucracy.
Specializations: Inspiration, Maneuvers, Naval, Siege
