I think they should add the race of Vampire. You would be undead, can use a life steeling bite, efficiency increases with level. You suffer a -5 Charisma, your alignment can never go above -20, +1 perception, you can see in the dark, and can’t use your bite wile ware a helmet. During the night you would have +4 strength, +3 Dexterity, and +10 Damage Resistances. During the day you would have -3 Strength, -3 Dexterity, and -20 Damage Resistances. You would also haft feed every weak or so, or you would start to weaken. You might haft to store blood to drink. You might also be able to use a dominating bite on one person, but they would burst in to flame in the sun.
