Obsessive/Compulsive
The trauma, guilt or inner conflict that causes this derangement forces the individual to focus nearly all of her attention and energy onto a single repetitive behavior or action. Obsession relates to an individual's desire to control her environment - keeping clean, keeping an area quiet and peaceful, or keeping undesirable individuals from an area, for example. A compulsion is an action or set of actions that an individual is driven to perform to sooth her anxieties: for example, placing objects in an axact order, or feeding from a mortal in a precise, ritualistic fashion that is never allowed to vary.
Vampires with an obsessive or compulsive derangement must determine a set of specific actions or behaviors, as described above, and follow them to the exclusion of all else. The effects of obsessive/compulsive behavior can be negated for the course of one scene by spending a temporary Willpower point. The dificulty of any attempt to coerce or Dominate a vampire into ceasing her behavior is raised by one. If a vampire is forcibly prevented from adhering to her derangement, she automatically frenzies.
