The Code of Conduct trait means that the character adheres to a strict moral standing or self-imposed set of rules they follow at all times. Depending upon whether it’s a Minor or Major rait, this can be purely guidelines or a deep-seated way of life. The Doctor has a strict Major Code of Conduct, as he believes all life is precious and would even offer his hand of forgiveness and help to a Dalek or Missy. While this is listed as a Bad Trait, it doesn’t mean that having a code is bad; just that it can restrict your actions and limit your choices. Being good is often the harder option, but it means you’re a better person for it.
As a Minor Trait, Code of Conduct means that the character should try to do good at most times, and are unable to harm another being unless it is absolutely necessary and for the greater good.
As a Major Trait, their limits their actions dramatically, meaning they need to strive to do their best at every moment, almost verging on the saintly! Discuss the character’s own unique Code of Conduct with the Gamemaster when you take this trait. Breaking it may be very costly, resulting in the loss of Story Points!
