Bounty Hunt - NWN Side Quest (Chapter 2)
Port Llast: Bounty Hunt is a side quest that begins by speaking with Kendrack inside of Kendrack's Barracks in Port Llast. For this quest you'll need to hunt down 5 prisoners that have escaped from the Waterdeep Prison and return their tattooed ear to Kendrack as proof of kill.
Each of these prisoners is found in different locations throughout Chapter 2 and you'll encounter most of them while exploring areas and completing the main story quests of this Chapter. At first only 4 prisoners will be available to you, once you've turned in all 4 of their tattooed ears you'll be able to hunt down the final prisoner, Yesgar.
Below you'll find a list of each escaped prisoner and where to find them.
Zor: You'll find Zor inside of the Green Griffon Inn which is a building on the northern-most North Road map; use my screenshot below if you need help finding it. Zor is a Minotaur that's found on the 2nd floor of the Green Griffon Inn.
Wyvern: Wyvern is found in the northwestern portion of the Neverwinter Wood - Druid Encampment Map. He'll ask you to follow him into an ambush where he will summon 2 animals the first time you meet him. Like with all other prisoners he'll surrender when his health gets low enough.
Stirge: Stirge is found on the South Road map in the northwestern corner. There is a map marker for Old Tree Hollow in the exact spot that Stirge can be found.
Delilah: Delilah is found inside of the Archaeologist Barracks in the East Road map. Speak with Jax outside of this building and accept his quest to get the key that opens the doors leading inside. You'll find Delilah on the second floor of this building.
Yesgar: Once you've obtained all 4 of the other ears you'll need to return to Kendrack and talk with him about his kidnapped daughter. He'll give you the Port Llast Mine Key which you can use to reach Yesgar. You can find Yesgar inside of the Port Llast Mine which is in the first North Road map just north of Port Llast. The mine itself is pretty linear and you shouldn't have trouble finding Yesgar inside of it.
After eliminating Yesgar don't forget to rescue Shaldrissa, Kendrack's daughter. She can be found in a small jail cell connected to Yesgar's room. With her rescued and Yesgar slain all that's left is to return to Kendrack and turn in this quest.
