[ Rarely does John have such a willing (and easy-to-pick-on) audience. How could he say no? His new friend takes a fortifying drink, and John pours himself a fresh cup of blood. ]
Short version: imagine for a moment that you can see the heat of an object. [ He holds up a hand, palm open in demonstration. ] A living human body, that glows pretty bright. Blood outside the body... [ He tilts the cup with a finger hooked into its handle. ] Dimming down, losing energy. And the table? Hardly anything there.
Now, necromancers [ which he says with easy calm, just carries right on past it, ] can sense life and death just the same. A human body is full of cells being born, cells dying off. Outside the body, a sample will run its course, then fall to match ambient levels. Some substances seem to hold energy longer, conduct it better. Blood's great for that.
[ This time he dips a bare fingertip into the cup. When he withdraws it, the blood stretches up with his finger, gone viscous and stringy. ]
That energy can be turned to a purpose. Nudge platelets into clotting, for example.
