Hopping Vampires are among the first creatures players will encounter upon entering the Warrens. Four of them will appear out of nowhere, together with several Thought Stealers. One group will appear in front and one group behind players who go down the path into the first room of the Warren. Hopping Vampires are suicidal creatures, who will chase players down and when coming into touch range kill themselves, taking the player down with them. They kill in one hit.
