1. As a Woman, the size of your breasts is increased by one cup size. As a Man, your Penis grows by one penis size. As a Futanari or Herm, you may choose to increase the size of either your breasts or your Penis.
2. Immediately go into heat, comparable to a cat. For one week, every three months, this heat cycle will repeat. During heat, you will remain incredibly aroused to the point of being barely able to sleep. The only way to calm this arousal down is to have sex, or wait for the heat to pass once the week ends. The arousal will continuously return throughout the week, even after sex as it will only temporarily stave the urges off for a few hours. This cycle will become a permanent phenomenon, only interrupted by pregnancy or serious illness. (This is an inheritable trait.)
3. Grow a fully functional penis, complete with balls and sack. (If you already have 2, lose all of them.)
4. Your body, as well as any body fluids you give off now smell of a smell of your choice. (The default smell is the smell of buttered popcorn.)
5. Grow a pair of fully functional, typical demon horns in either black, violet, red or dark purple color (you may choose which, otherwise it defaults to black). (This is an inheritable trait.)

(Decided gender by a coin toss/1d2 in the case you are a futa or a herm.) The vampire will not be able to approach other people participating in the game, and other participants will be unable to perform any actions with the intention of helping you or keeping the vampire from doing anything to you. The vampire will be unable to in any way intentionally harm you. (Biting you in order to feed off of your blood is an exception as long as it doesn’t drink enough to harm you, or if it is done to turn you.)
