Fugue
Victims suffering from fugue experience "blackouts" and loss of memory. When subjected to stress, the indivual begins a specific, rigid set of behaviors to remove the stressful symptoms. This differs from multiple personalities, as the individual in the grip of afugue has no separate personaltiy, but is on a form of "autopiolet" similar to sleepwalking.
Kindred suffering from this derangement require a Willpower roll when subjected to extreme stress or pressure (difficulty 8). If the roll fails, the player must roleplay her character's trancelike state; otherwise, control of the character passes to the Storyteller for a number of scenes equal to the roll of a die. During this period, the Storyteller may have the character act as she sees fit to remove the source of the stress. At the end of the fugue, the character "regains consciousness" with no memory of her actions.
