To obtain this perk, convince Vance to enter into a deal with the town of Arefu by passing a Speech check, a Medicine skill check, or an Intelligence check at the conclusion of the Blood Ties quest. Then return to Vance and ask to be shown the ways of the vampire.
- If you finish Blood Ties by killing The Family then you won't be able to get this perk.
- If between finishing Blood Ties and attempting to get this perk, you kill anyone in Arefu or become hostile with Arefu or The Family, Vance will not teach you this perk, and call you an "asshole".
Behind the scenes
- Hematophagy is the habit of certain animals feeding on blood (from the Greek words haima, blood, and phagein - to eat).
