You either Randomly get bitten, when you are sleeping in a non-secure location. (eg. Beggars bed, Arena beds.) or ask the vampire in the dark brotherhood once you have finished getting assignments from him.
You cannot turn into a werewolf in Oblivion, though you can turn into a vampire by being bitten by vampires, though there are another source of becoming a vampire, you find it out, I am not going to tell it...
No, you do not. You can only become a vampire by being bitten by one, either contracting Porphyric Haemophilia from vampire enemies, or by allowing Vicente Valtieri to turn you into one.
find vampires and let them attack you until it says you have contracted what ever the diesese is called then sleep or do lots of dark brotherhood quests and a vampire will offer to turn you into a vampire.
no u cant you can be a vampire
there is no posion that will turn you into a vampire but a vampire blood can turn you into a vampire
Yes. Just become reinfected from another vampire later.
If you are a vampire, a blood potion replaces the need for a feeding.
I am lvl 15 and I can buy them.
before you completely turn there is a quest for a cure, but if you do not do that quest in time then the change is completely unchangeable.
Other vampires can turn you into a vampire.
As a vampire you get new spells and can suck peoples blood, but you are disliked by people and are rapidly damaged by the sun.
Vampires are not real then there is no way to turn into a vampire.
