In addition to earning and spending Experience, players can tweak their characters after each session. Tweaks are small, cost-free changes that help a player customize her character to fit the story and her style of play. Players cannot, at character creation, fully anticipate how their characters will work together or the types of the problems they will need to solve. Tweaks help counter this lack of prescience.
Players may tweak their character sheets in the following ways.
Shift one dot from one Attribute to another Attribute or from one Skill to another Skill. At the start of a new session, a player must announce the dot shift and must mark on his character sheet the Skill or Attribute he plans to change. During that session, the player must roleplay using the Skill or Attribute he wishes to increase; this can be as simple as creating a dice pool using the trait.
Swap out an existing Knack for a new Knack. If the character has purchased a new Knack, they may “swap” out their known Knack for another. At the level of Scion: Origin, characters may only have one Knack active at a time.
Write a new short-term Deed. At the start of each session, a player can set a new short-term Deed even if his character did not achieve his short-term Deed in the previous session. Again, a character can only have five Deeds active at any one time.
