Multiple Personality

Severe; extreme; follows Irrationality

World of Darkness Rulebook / Vampire the Requiem
The trauma that spawns this derangement fractures your character's personality into one or more additional personas, allowing her to deny her trauma or any actions the trauma causes by placing the blame on "someone else." Each personality is created to respond to certain emotional stimuli. An abused person might develop a tough-as-nails survivor personality, create a "protector" or even become a murderer to deny the abuse she suffers. In most cases, none of these personalities is aware of the others, and they come and go through your character's mind in response to specific situations or conditions.
Multiple-Personality Disorder (MPD) results from traumas so severe and prolonged that the victim’s mind splits into several personalities. When a vampire suffers this derangement, the Storyteller and player need to agree on a set of alternative personalities for the character, as well as on what situations call each personality to the fore. Each personality should have some connection to the trauma that fractured the character’s mind. Alternate personalities might believe they belong to different clans, bloodlines or covenants, or even not be aware that they are undead.

Symptoms

Effect: A character with multiple personalities can manifest different Skills or perhaps increased or diminished Social Attributes for each identity (the number of dots allocated to your character's Social Attributes are rearranged by anywhere from one to three).
A character with multiple personalities can manifest different Skills or perhaps increased or diminished Social Attributes for each identity (the number of dots allocated to your character’s Social Attributes are rearranged by anywhere from one to three). The character does not actually possess more Skills than other characters, he merely switches personalities when he needs to use certain Skills. For instance, a tough-guy “protector” persona might emerge whenever the character needs to fight, so the baseline identity doesn’t need to face the moral and emotional stress of combat. The “protector” persona takes possession of the character’s combat Skills, while the other personalities don’t admit that they know how to fight.
This is an extreme derangement. The character must experience a life-altering trauma or supernatural tragedy to manifest it. The ailment cannot normally be acquired by failing a Humanity roll unless the sin performed is truly ghastly. MPD is an elaborate derangement, and a challenge to roleplay. Its symptoms are frightening and the suffering it exacts from its victim is monumental. It should not be an excuse for slapstick, wacky, foolish or childish behavior.
