I get it... They drink blood to live, die from a stake through the heart, sunlight hurts them (usually), I understand the basics... Every story has a few changes to it though:
Go to ancient lore instead of the mythos which has developed within the past few centuries if you want to really know about vampires. You'll discover that there basically are three different types of vampires: The original vampires, vampires made into vampires by other vampires, and vampires made into vampires through a spell or curse. The original vampires can venture out into daylight, but are severely weakened by it. They can morph into several shapes and can give the illusion of morphing as well. They are humanoid in shape but clearly not human. Silver can poison them but it doesn't kill them. The wood of an oak tree through their heart will kill them, as will beheading and burning their bodies to ash. Their reflection in objects is blurred but still exists. Things like crosses and holy water are meaningless to them. Garlic does not affect them but rather the pollen from a flower of the garlic family (which is true of all vampires). They are unable to cross over running water, which is why they originally made other vampires. The vampires they make are under their servitude. Vampires made into vampires by other vampires cannot venture out into daylight without quickly dying. While their strength is greater than that of a human it is about half that of an original vampire. They require more blood than an original vampire does to survive on, or must spend more time at rest to regenerate. Again, it is the wood of an oak tree through their heart and not just any wood that will kill them. Silver poisons them and can eventually kill them, although death through silver poisoning takes a long time. Crosses, holy water and all that stuff doesn't work on them. Vampires made vampires through a spell or curse are confined by the content of the spell or curse, so their various strengths and weaknesses will vary accordingly. If the spell or curse is religious in manner, then items such as crosses, holy water and other religious artifacts will work on them. Vampires would take professions which allow them ready access to blood without people questioning the loss of blood, and would allow them to stay indoors during the daylight hours. Barbers were the preferred profession for many a century since barbers also acted as general physicians in many a small town and village. Vampires also normally would partake of blood from an area that would or might be hidden by clothing, The inner thigh, inside elbow or knee, underarm, between the toes, genitalia, etc. Rarely would they bite someone on the neck. Usually that was only done if they were in a hurry, and then they would try to cover it up by ripping out the throat and making it appear to be a wild animal attack. Biting on the neck would advertise their existence which they tried to avoid.
