In order to become a vampire you have to get into a fight with a vampire. If you are an Argonian its harder to get the desiese because of the resist desiese atrabute. An easyer way to do this is to get into the dark brotherhood. After a certin amount of quests one of the people will let u become a vampire. After three days of geting the vampire desiese, you will be a full vampire. You will have to sleep to become the vampire though. When you sleep after the three days you will have a dream about being being a vampire. After the you wake up you will notice that your skin has been turned pale and that your eyes are a redish kind of color. To stop this from happening you will have to go to a town chaple and pray.(If there is anything that you feel that I forgot to include the write a comment about it)
