You can’t be in direct sunlight, you can’t be near any people with strong religions, your shape and first ability is decided by the one that made you, you have to drink blood three times a day, and can starve like any human, except your body also has a mind of its own, and if you don’t feed it, it will rampage. You get one random ability per every century you live through, you get one official familiar for every century you survive in, and you're three times as fast and strong, as the peak of human athleticism. You will die with a steak to the heart, and are immensely flammable. Welcome to the vampire problem. Good luck surviving.
