Red Fear

Rötschreck

Rotschreck "The Red Fear" is a condition caused by a character failing a Courage roll against an attack by or even the sight of Fire or Sunlight, which are among the few sources of injury that can destroy a vampire. It is similar to Frenzy in that it is a compulsion that is difficult to control; characters under Rötschreck will hysterically flee from whatever caused the frenzy.

The difficulty of resisting Rotschreck and its effects varies. In the worst case scenario, a vampire under the spell of this Rotschreck is completely controlled by their inner Beast, instinctly driven to a flight-or-fight mentality and forced to flee blindly from the source of fear while they remove any obstacle or person in their way regardless of their personal attachments with them.

In the Book of Nod, Archangel Michael clearly states, while cursing Caine, that he and his children will fear the flame and it will hurt them deeply, causing unbearable agony and pain; Vampires have been cursed not only by weakness to Flame but also fear of it.
