Manic Depression
Manic-depressives (also known as bi-polars) suffer from severe mood swings, sometimes resulting from severe trauma or anxiety. Victims may be upbeat and confident one moment, then uncontrollably lethargic and pessimistic the next.
Kindred with this derangement are constantly on a hair trigger, never knowing when the next mood swing will strike. Whenever the vampire fails a task, the Storyteller has the option of secretly making a Willpower roll (difficulty 8) for the character. If the character fails the roll, she lapses into depression. Additionally, the vamprie will go into depression whenever one of her rolls is botched, or if her blood pool ever drops below 2. The Storyteller should roll a die to determine how many scenes the character remains depressed, keeping the number a secret.
Vampires in a depressive state have their Willpower ratings halved (minimum 1). In addition, the vampire may not access her blood pool to raise Attributes. Upon emerging from the depressive state, the character is energetic, relentlessly upbeat and active (obsessively so) for a number of scenes proportionate to the time spent in depression. When a vampire is in this manic state, the difficulty of all rolls to resist frenzy is raised by one.
