Can heal gunshots

"Can't hurt," I said. "You might get lucky and solve our problem. But only a really critical shot will drop him, and even then it's iffy whether or not you'll get him. White Court vamps don't soak up gunshots as well as Red Court vampires do, or ignore them like the Black Court, but they can get over them in a hurry."
"How?"
"They have a kind of reserve of stolen life-energy. They tap into it to be stronger or faster, to recover from injuries, forcibly manipulate the sensations of police lieutenants, that kind of thing. They don't run around being as tough as the Black Court all the time, but they can rev the engine when they need to do it. It's probably safe to assume that Lord Raith has a great big honking tank of reserve energy."
