Rex Sanguis Sacrorum

The mind does not survive Torpor easily. Nightmares besiege the unconscious. Memories twist and tangle like a wall of swiftly-growing vines. Elements submerge beneath a demented fog. But for those who know this ritual, sacrifice can make it all better. The vampire must first blood-let an animal, human or vampire, inflicting a number of lethal points of damage equal to the character’s Blood Potency score (yes, this may kill the creature). The blood must be spilled into a censor, where it is mingled with the vampire’s own Vitae and then burned. As the acrid smoke rises, the vampire must whisper entreaties to Ianus, beseeching the god to look backward through the vampire’s Requiem for some kind of clarity. For the remainder of the night, the vampire’s mind is not given over to The Fog of Eternity, and she can remember everything about her Requiem without having to overcome torpid dementia (though the Storyteller may still require an Intelligence + Composure roll to remember certain things).
This ritual has a few restrictions. First, all the blood sacrificed to Ianus must come from a single creature. So, vampires of higher Blood Potency must sacrifice larger and larger animals… or, of course, humans. Second, the vampire may only cast this ritual once per week, with the exception being during the month of January (Ianus’s month, the beginning and end of the year). During January, the ritual can be applied every night.
If the vampire chooses to sacrifice another vampire, however, the effects of this ritual last a full week instead of one night.
