Well, if u want more Blood Magic show, you'll have to let him mock them, taunt them, let them suffer, since if he gets serious, he can one shot them spending most of his Blood Essence to create an Armageddon of Blood Spears and pull a Gilgamesh-style Gate of Babylon on those Vampires. Well... that might be an idea for later.
