This type of warding circle guards against vampires other than the caster.

Ingredients: The ritualist inscribes the warding circle with a rowan stick dipped in a mixture of Blood and warm ash from a still-burning fire. 

Process and System: In order to gather the ash ingredient for this Ritual, a vampire takes one level of Aggravated Damage and must test for Terror Frenzy at difficulty 2 because of the proximity to fire. If this causes a Frenzy, the ritualist may not attempt to cast this Ritual again the same night. This Ritual uses the standard rules for warding circles and considers any vampire other than the caster to be a trespasser. 

Duration: Until destroyed
