Ability Score(s): Rhetoric + Voice
Usage: There are three subtypes of Comedy skill; Buffoonery, Pun, and Physical. Comedy is a delicate art which can easily backfire in the hands of the inexperienced or poorly endowed (comedically). Although humor is largely subjective, this skill focuses both on how commonly you're viewed as "funny", and how well an audience or individual takes your attempts to make them laugh.
Normally Comedy is tested against the Mental Defense if you're trying to make an individual or a handful of individuals laugh or be amused. Some who are less inclined to emotions may have bonuses to Mental Defense against it at GM's discretion.
With an audience, you are often testing against a DC based on how receptive they are toward you as well as their comedic tastes (determined by GM; they either like Buffoonery, Puns, or Physical, or a combination of two or all three, or rarely none). Base DC is 20 and is increased by 5 if the audience is unaware of who you are or 10 instead if they know you and don't like you. DC is reduced by 5 if the audience knows and likes you. In addition if your type of comedy matches the audience's preference the DC is decreased by 5, and increased by 5 if it doesn't match their interests. If they don't like comedy at all, it's increased by 10 instead.
