At night between 10pm and 1am go into a dark room and think of the qualities of a vampire and picture you having them this could be either drinking blood or running faster than a normal human.
do this outside for better results.
then chant the following 10 times
blood red, pale skin,
moonlight draw me in,
quench my thirst,
coursing veins,
let my body feel no pain
the following side affects are
headache
slightly sharper K9s
a small thirst for blood
food may taste a bit funny at first (you will get used to this)
a deep black ring around your eye
faster and stronger
sun will feel hotter and you will burn easier
