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.
System: This ritual was developed by a young aspiring member of Wards and Measures, as a means of further ensuring that valuable secrets of the Chantry do not fall into the hands of their enemies. To enact this ritual, the caster must drain a Blood Trait from each member of the Chantry and cast it into a fire fueled by the blueprints of the Location that they are attempting to cast this protection upon. A copy and not the original will suffice. After the fire dies down, the ritualist must anoint a small spot above each portal leading into the protected location. This leaves small telltale black marks for those who know what to look for and are often mistaken as just a dirty spot on the surface it sits upon.
Until the end of a month, while inside the protected location, the participants in the ritual are aware whenever another entity uses supernatural powers to actively spy upon the Chantry and them. Thus allowing them to end conversations before giving away valuable secrets or hide whatever secret materials the hidden observer was after. The participants also discovers the type of attempted surveillance - listening, watching, telepathic contact, etc.
This ritual does not protect against supernatural powers that do not directly spy on the user; for example, it will not detect a Nosferatu using Obfuscate to stand in the corner and listen to what is being said, because Obfuscate is not providing him with any information. However, if they used Heightened Senses to listen in on the conversation, the ritual functions normally. Likewise, this ritual won’t immediately detect a character employing Telepathy to send the recipient a message, but Telepathy attempting to plumb the user’s mind for information would be detected. Last but not least, it does not block conventional eavesdropping. If the participants are careless enough to let someone overhear or otherwise spy on them directly, that’s their own problem.
At storyteller’s discretion, particularly mighty elders or similarly powerful creatures may be immune to this ritual, though this should be rare and reserved for those who have specifically cultivated their talent at supernatural surveillance, or else this ritual quickly loses its usefulness
This is considered a Haven Ritual and may be augmented by other rituals that affect havens as well.
