Advancement
Resistance Toolbox
Advancement forms the core of the game - it dictates how characters grow in power, and what their aims and actions are, and as such the central reasons for advancement is a very important design decision to make.
Picking it out is one of the hardest parts of your job; it can’t be too easy, or too hard, and it has to encourage the right sort of play. Don’t be afraid to change or modify it halfway through as your setting and system grow around it.
Depending on the scale of the actions performed, you might divide up advancement into size categories - Minor and Major, or Low, Medium and High, for example. When a character advances, their player can select an additional ability from the lists available to them.
