Core:Agency Sparks

At the start of each game session, every player character gets one spark of agency (or "spark"). This can be spent at any time to re-roll an attack roll, feat save, tradecraft check, or resistance save. Once re-rolled, the player can select which of the two rolls they keep. Sparks of agency must be spent in the session they are given or they are lost. The GM may choose to give award additional sparks at their discretion as rewords for excellent role-playing, daring acts of bravery, or anything else they deem appropriate. A character cannot have more than three sparks at any time. Finally, a player can choose to spend all of their character's sparks to immediately awaken at any time.
