No spells nor rituals that will work.
Yes, you have to be born that way.
It is a genetically inherited illness,
not a contagious disease.
Even if it were contagious
or you were somehow capable of "turning" yourself,
there really aren't any good sides to it
so doing that would not be what most people would call smart.
I must agree with the post from above.
There is no spell that can turn you into a vampire, it is strictly hereditary- and even in that, there is great speculation that Vampirism is only a mental condition.
ill tell you rite now, you have to be this way, i dont want it and it still haunts me every night when i try to sleep like normal people do. or when you almost attack your fiance when she cuts herself in the kitchen, trust me.....you have to be born this way.
