Term: Retrain

Retraining, often called rerolling, offers a way to alter your character choices, which is helpful when you want to take your character in a new direction or change decisions that didn't meet your expectations. You can retrain any aspect of a character, except for their Ancestry and Heritage.
There's no hard and fast rule for retraining, with the GM's permission and some Downtime being needed, usually between Sessions or during a particular narrative ordeal.
Optional Rules exist for those who want them, too. Such as Optional Rule: Retraining with Time or Optional Rule: Retraining with Costs.
