The quest should not be a problem at all. You will find barghests just everywhere in the outskirts at night. Look for rabid dogs or do the Vesna Hood quest - both are guaranteed locations for barghests. After you have collected ten skulls, see Abigail for a nice XP boost and some coin.
- You do not need the Barghest entry in your bestiary journal to complete this quest. Barghest remains contain their skulls with or without the entry.
Barghest Skulls Edit
Abigail, the local herbalist, will pay cash for barghest skulls. I should see her as soon as I collect the number she needs. I must collect ten barghest skulls for Abigail.
I have enough barghest skulls to collect my reward. I should see Abigail. I should see Abigail and collect my reward.
Abigail paid me for the barghest skulls. Job done. I received my reward for the barghest skulls. (100 + 2000 XP)
