Genesis
It’s not needed as often as books and movies make it seem, just often enough to keep their senses sharp, their powers potent, and to, you know, not get hangry.
Same goes for the Vlokodlak, also known as werewolves. The biggest myth about them? That they need a full moon to change. Nope. A full moon might amplify their power, make the shift a little easier, but it's not a hard requirement. They can change whenever they want, though it takes a lot of energy and control. And here’s another big myth about both Upir and Vlokodlak: you can’t make them. They’re not contagious, you don’t get bitten and suddenly sprout fangs or fur. Vampires and werewolves are born, end of story.
