If the damage of an attack is a simple success (0-3 points over Toughness), the target is Shaken. Shaken characters are rattled, distracted, or momentarily shocked. They aren't stunned but are temporarily suppressed and may hesitate.

On their action, Shaken characters must attempt to recover from being Shaken by making a Spirit roll:

• Failure: The character remains Shaken. She can only perform free actions.
• Success: The character is no longer Shaken and may act normally.

Spending Bennies: A player may spend a Benny at any time to remove her Shaken status (even when it is not her turn).
