BLOOD AND YOU:
Races:
Demon Blood - Demon blood is essentially human blood because the demon needs a human host in order to survive. Snacking on a demon will grant you the same nourishment as a human.
Fae Blood - Tastes sweet. Very nourishing. Gives the vampire a sort of high, can cause hallucinations, or put them in a state of euphoria. This can impair the vampire's senses, depending on your character. Fae blood is very addictive.
Wolf Blood - The ultimate Red Bull. Makes you more powerful for a short time. Powers are easier to use. Strength, speed are increased. Wounds heal much faster.
Witch Blood - More nourishing and 'lighter' than a regular human's blood. You can take more and store for a longer period of time. This makes the blood very prized as it requires less feeding.
Human Blood - Mmmm, people. Human blood is, and will always be, the fount of life for vampires. More readily available, easier to come by. A vampire can not survive solely on the blood of other races. It needs human blood in order to remain animated.
Vampire Blood - Almost an act of sex for some. Very intimate. May allow for the exchange of memories. It's a pleasurable experience. Some vampires have a weakness in their blood that makes them irresistible to other vampires. Others carry a weakness that makes them unpalatable.
Blood from a blood bank - Once the blood leaves the body it is no longer 'alive'. Blood from a blood bank or 'bagged' blood will make you weaker. You will remain awake and animated, but you will grow weaker to the point that your stats are the similar to a regular human.
Blood from an animal - Animal blood is much the same as blood from a blood bank, though the effects of weakness take longer. Blood from animals will fill you up, but powers will eventually wane.
Feeding:
How Often? The vampire only needs to feed once every two weeks, but that's pushing the envelope. Essentially, that's going from a full tank to fumes. If you have a character that's prone to frenzy, probably one shouldn't wait that long.
How Much? Only a pint will do the trick.
The Kiss is what most vampire's refer to the act of feeding. A vampire naturally has the gift to put a human in a state of pleasure. This is why we have blood dolls - humans who are addicted to the act of being victimized. The act of penetration of fang on flesh yields no pain, unless of course that vampire has that as a weakness.
