How do Negative Traits work?
When you are in a challenge (see the Primer for information on challenges), you may attempt to call a Negative Trait that your opponent possesses that is appropriate to the challenge. (Taking Lame [Physical] as an example: “You’re so Lame you can’t get past this bouncer.” doesn’t work, but “You can’t catch me – you have a Lame leg.” does.) If your opponent has that Trait, he must bid an extra Trait or relent the challenge. If he does not have that Trait, you must bid an extra Trait or relent.
