Quick little system based on Milestones from Fate. This allows for characters to change on a deeper level than notches and experience allows. You can't change the world without the world changing you.
Character Advancement
When the Cabal completes an Objective, each player can pick an Advancement option for their character. This reflects how their actions and experiences have changed who they are. Each entry lists possible in-character justifications for picking that option.
Change Obsession: Obsessions can be refined or redirected. Given the pull of obsession, it works better to move this in a related direction. The Obsession Identity can be swapped for another available Identity but the Obsession must tie into the new Identity selected.
Possible cause: Revelation, ideological confrontation, loss of interest
Change a Passion: A Passion no longer fits who you are and can be rewritten. When you change your Fear Passion, pick an appropriate Stress Meter.
Possible cause: Frequent Self checks, productive therapy, a memorable event
Change a Relationship: Move a Relationship to a more appropriate type. (Favorite becomes Responsibility, Mentor becomes Protégé)
Possible cause: Straining connections, shifting feelings, new social dynamic
Replace or remove a Relationship: Swap one of your Relationships out with a different person or group, or remove a Relationship entirely. This does not cause a stress check since you did not actively work to destroy the Relationship but they may be caused by interactions with the previous Relationship.
Possible cause: Moving on, new friend group, emotional distance
Gain or replace a Mundane Identity: If you have an available slot for an Identity, you can gain a new one starting at 15%. If you are at your limit, pick one to replace with a new Identity at the current percent minus 1d10+5%. An Obsession Identity cannot be replaced.
Possible cause: New job or hobby, growing pains, self reflection
Improve a Mundane Identity: Gain an extra Feature. If an improved Identity is replaced, the new Identity has the default amount of Features. Can only be picked once per Identity.
Possible cause: Dedication, self-improvement, increased knowledge
Therapy: Remove a hardened or failed notch of your choice. Stress meters with five failed notches cannot be selected.
Possible cause: Relief from tension, internal processing, personal success
