Boddyknock's Tale - NWN Henchman Quest (Chapter 3)
Boddyknock's Tale is the third and final quest that's given to you by Boddyknock, one of the available Henchman in the Neverwinter Nights Main Campaign. Every Henchman will have a unique quest that will become available from talking to them during the chapter. These quests are locked behind character levels, if your Henchman tells you that they will "finish the story later" it means you have to level up more.
Note: If you did not complete this Henchman's quest during Chapter 1 and Chapter 2 then it will not be available to you during Chapter 3. Also, if you did not keep their quest reward with you from Chapter 1 and 2 then they will be unable to upgrade it and may not offer you the quest either.
For this version of Boddyknock's Tale you're tasked with obtaining a Dragon Scale which is found inside of the Brass Dragon Cave located in the Spine of the World map. You can reach the Spine of the World map by traveling through 2 Moonwood maps - both of them lead to this one.
You'll find the Brass Dragon Cave in the western portion of the map inside there will be some giant bodies along with the body of a Brass Dragon (pictured below). There's really not much else to collect inside of this cave, the Dragon Scale we need is found inside of a pile of dirt near the body.
