Only usable when an action is announced. Vampires cannot block this action. This acting vampire is treated as a mortal ally for the duration of the action (cannot spend or burn blood, cannot use Disciplines, will burn if reduced to 0 life, etc.). The vampire's blood represents his or her life while he or she is an ally. Only usable on an action that doesn't cost blood or require a vampire, clan or Discipline. Burn option.
