Vampires are nocturnal creatures and find it difficult to awaken during the day. A vampire disturbed in his haven while the sun is in the sky may roll Perception (+ Auspex rating, if the vampire has it) versus difficulty 8 to notice the disturbance. Upon stirring, the vampire must make a Humanity roll (difficulty 8). Each success allows the vampire to act for one turn. Five successes mean the vampire is completely awake for the entire scene. Failure indicates the vampire slips back into slumber, but may make the Perception roll to reawaken if circumstances allow. A botch means the vampire falls into deep sleep and will not awaken until sundown.
While active during the day, the vampire may have no more dice in any dice pool than his Humanity rating.
