Do you think spell casters can duel vampires?

I currently have twins between vampire and spellcaster. They are now teens and they have vampire menu and magic menu. They can bind familiars.There's no dark form in cas. None is appeared they are spellcaster or vampire in cas either but they have spellcasters ranking bar on vampire needs. Human food doesn't fill their thirst bar, so they have to drink plasma I think. I need to play more.
