Cobra Fangs
A character using Form of the Cobra gains a venomous bite along with his serpentine form. Unfortunately, huge black cobras tend to make people run away as fast as they can. This Serpentis power enables a Setite to gain the deadly bite without the full-body transformation, making it more useful for taking victims by surprise. The police do ask questions when someone dies from a cobra bite under unlikely circumstances, so Cobra Fangs still requires some discretion.
System: The Setite expends one blood point, and in one turn his fangs become hollow, more slender and venomous. The vampire injects venom when he bites. He must still grapple with the victim to deliver a bite attack, and the bite does the usual amount of damage; the venom, however, kills mortals within one minute. Bitten vampires or other supernaturally resilient creatures suffer ten health levels of aggravated damage, minus one per dot of Stamina, over the course of five minutes. This damage may be soaked with a single roll of Fortitude by vampires and Stamina by Werewolves.
