Custom Blood Magic: Ritual
Some chronicles allow for their players to develop customized powers for their characters. The following is a compilation of player created custom content in OWBN. At this time, custom content that is created and/or used by vampire PC's is required to be listed.
The known final mastery of the Inscription Ritual. Its most potent form allows the Thuamturge to inscribe their most powerful rituals they may know. This generally requires the equivalent of a full page of paper. A reader can then unlock the power of that ritual by reading the inscription and following its instructions. The scribe uses his blood as a base for the ink, and his vitae’s power remains in the mixture to help fuel the ritual. An inscribed ritual is in imperfect form - it cannot be used to learn Thaumaturgy. It’s a simplified set of instructions, with the scribe’s vitae empowering the rite so that it overcomes any omissions or sloppiness on the part of the practitioner.
System: A thaumaturge who knows the techniques of Supreme Inscription can write an abbreviated form for any fifth-level ritual that he knows, at a cost of four blood points. Anyone who can read the language may then use the ritual notes later. Actually casting the ritual from the notes requires the use of the usual components and time, as well as the standard Mental Challenge, but the caster need not have any knowledge of Thaumaturgy. Once an inscription is complete, the power of the writer’s vitae is trapped in the object; his maximum blood pool is effectively reduced by three until the inscription is used. After use, the inscription dries into a fine, illegible ash, withal1 the power expelled from the vitae-based ink. The scribe can use the scroll himself (which is rather pointless) or give it to someone else. To prevent an inscription from reaching the wrong subject, many scribes also use Encrypt Missive (Blood Magic: Secrets of Thaumaturgy, p. 87) with this ritual.
It is known that the blood powering Inscription can be used for links of Sympathy and Identity an incautious Tremere could find his blood in the hands of an enemy who can use it against him.
A Storyteller must be present for you to use Inscription. You give your Blood Trait cards to the Storyteller, who should make a special mark on your sheet (placing an “I” over each used Blood Trait circle is a good idea). Place your Inscription upon an item card, with a note of the ritual and your character’s name (so that the Storytellers can tell who wrote it when it’s used up).
