Two hours and thirty-nine minutes of Savathûn's campaign, the longest session in the Witch Queen playthrough. Doubt as weapon is the expansion's central mechanic — the Guardian is asked to doubt the Traveler, doubt the Light, doubt whether the distinction between Light and Darkness is as categorical as the City's theology has always claimed. Savathûn weaponizes this doubt by showing the Guardian a Throne World where everything they were trained to oppose looks functionally identical to everything they were trained to defend. Aim carefully because doubt misdirected destroys the people using it.
