As each stage of vampirism increases, some effects stay the same, while others change. You can only drink blood from sleeping NPCs. The longer you go without blood, the more powerful the benefits of vampirism will become, but the weaknesses will also get worse.
There are four stages of the disease of Vampirism. But, if you want to turn into a vamipre, you can wait three days and the disease will become permanent When you are fighting against vampires, you also have a chance of contracting vampirism each time they land a hit on you – that could turn you into a vampire! If you contract the disease, it can be cured with any of your regular disease potions.
