In White Wolf Game Studio's role-playing games set in the World of Darkness, a frenzy is a temporary state of rage and lack of self-control that a vampire character enters as a response to certain stimuli. During the frenzy, the vampire's inner Beast is in control. The most common causes for a frenzy are: Some vampires can and do deliberately induce frenzy ("summoning the Beast"), and then try to direct their instincts ("riding the Beast") for specific purposes.
