- Kill Hern inside Half-Moon Mill.
Hern is a fairly easy kill, even if he is a vampire. He is usually inside Half-Moon Mill’s home with his wife. They can both be killed with any weapons. As long as Hern dies, the mission completes.
During the day, you’ll find him outside — unusual for a so-called vampire — hanging out on a bridge. You can sneak into a shack next to the bridge and snipe him safely from an open window. His wife usually won’t notice if it’s a one-hit kill. As long as you don’t have this quest, only his wife will be present at the mill. You can kill her before getting the quest to make killing Hern slightly easier.
