Vampires, they need human blood, they can't drink demon or other races they could posion them. Elves, sneaky creatures with very good with archry and mickry with animals but they can't shapeshift. The sins- The seven sins are very powerfuul demons with infulences on both demons and other races. They are weak though in sense they are connected to sin if people don't get temped, or anything the sins start to loose power.
