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.
This simple ritual lets the caster detect the "scent" of Demons in the area. The thaumaturge prepares a small herbal bundle with milkweed, holy water, sage and a handful of simple grass. With a short set of phrases she takes a whiff from the mixture, after which she can immediately tell any Demonic presence by scent. This does not mean that she can detect Demons at a distance, merely that she can tell if a person or anything they are carrying's smell happens to be demonic, which can be useful when combined with augmented senses.
System
The thaumaturge simply completes the ritual and sniffs from the herbal bundle. Afterward, she can detect Demons by scent; actually sniffing someone up close would require no test, but catching a scent at a distance of a few feet might take a Static Mental Challenge (difficulty 6). Detecting a Demon hidden around a corner, for example, could increase the difficult to 8. The scent distinction lasts for an entire scene.
