Modren vampire rules

1.They need blood. Mostly. Usually Vampires go insane/grow weak/die without it, or degenerate into mindless, rabid monsters.
2.They are capable of changing human beings into other vampires. Classical vampires like Dracula needed to go through a more elaborate process to make another vampire, but bowdlerized versions removed the detail where he made the victims drink his blood to begin the transformation, leading to the idea that victims can become vampires from just a bite.
3. Recently, the idea has arisen that vampires judge each other by how far removed they are from a "source". The highest social status belongs to a Vampire Monarch who somehow became a vampire without being turned by one via bite; or else the next person below them if their spawn gets a Klingon Promotion.
4.Of course, there can also be a fusion of "types". A vampire may create mindless undead slaves via simple feeding (often referred to as "spawn"), but to create a thinking vampire with the potential for the gambits of powers, the full process is needed.
5.Or they create living servants like ghouls or blood-slaves who feed on their blood, get power from it somehow, and protect their masters any way they can. Vampire blood has often been depicted as having the power to extend the natural lifespan of ordinary humans, allowing them to bribe mortals to their service with drops of blood.
6. Vampires are almost always inhumanly strong, fast, and durable, often to the point of being Immune to Bullets and most other mundane weapons. For some, especially more modern ones, this is where it ends, making them effectively little more than intelligent (and stylish) super-zombies.
7. Achilles Heels.
8.No reflection (often because the vampire has no soul, but see below). This sometimes extends to shadows. But it depends on the vampire apparently. In one medium there are several types of vamps who have various weaknesses. In more recent examples this has been 'modernized' in terms of the vampire not being able to be picked up by audio or video recording or transmitting equipment.
9. The Undead: Technically, they are dead. Pretty spry for a dead guy, though.
10. Cannot be photographed or caught on video, often an extension of the "no reflection" rule. This may also be related to the silver rule; mirrors and photographic film are both (usually) made from silver. It may also apply only to SLR and TLR cameras, where a mirror deflects the image from lens to film.
