Torture sessions can last as long as the torturer wants them to.

Roll [ Medicine vs the captive's Constitution ] and select one or more Body Parts on the captive.

Success means the captive takes 1d6 Trauma and 1 Damage for each selected Body Part.

Failure means the captive takes 1d6 Trauma and 1d6 Damage for each selected Body Part.

Roll [ Demeanor vs Demeanor ] at the end of each torture session.

Success means you take 1 Trauma and the captive's spirit is broken, meaning that they will do or say whatever they think will stop further torture until they are freed.

Failure means you take 1d6 Trauma from inflicting torture on another human being and the captive continues to resist.
