When blood bathers and vampires meet, the results are usually violent in the long term: blood bathers, after all, bring trouble in the form of hunters note , law enforcement note , and scarcity of food note . Another source of conflict, though is that once a blood bather has completed the Bathing Ritual, the blood becomes inert. It is useless for transfusions or any other medical purpose, and it is useless for any other mystical use - including consumption by a vampire. Once the local undead discover that someone is killing the living, draining their blood and making that blood useless, they will probably find a way to kill the blood bather. Or at least, they can try - blood bathers aren't exactly easy to kill.
