"Pale. If you're already pale for a human when you turn you wind up almost pure white; people who were darker stop getting paler only just short of that. Eye color changes, depending on recency of turning and diet. Thirsty. Volatile for the first while, although that shortens and attenuates considerably when people know what they're getting into ahead of time. Very strong, tough, fast, precise. Perfect recall. Turning symmetrizes and smooths out, so many people like their looks better afterwards. Vampires don't sleep. It often improves or sometimes even adds de novo witchcraft. Vampires can completely heal from any injury without scarring as long as the injury wasn't inflicted by another vampire's teeth, all the pieces can be found, and they're brought into contact with their missing parts soon enough that they haven't completely dried out. They smell bad to werewolves, and vice-versa. Female vampires can't bear children. And they're about room-temperature, a little colder."
