The Ghoul Contract (1)

Walkthrough
You will encounter ghouls while doing the quest for Mikul. Since there aren't many ghoul spots in act 1, be sure to read the book about ghouls before venturing into the crypt. After you've finished Mikul's quest there's a new passage in the crypt where you encounter more ghouls and a named alghoul. Every night there's also a ghoul which feasts on some corpses at the abandoned houses north of the cave. Collect three vials of ghoul blood and return to Kalkstein who resides at the local inn.

Ghoul Blood
Kalkstein the alchemist will pay for the blood of three ghouls.

Loot
I have enough ghoul blood. It's time to see Kalkstein and collect my reward.

Payment
Kalkstein is using the blood in some of his research. Interesting... In any case, job done.
