The Old Wandmaker asks the Hero to help him find some Corpse dust. The Corpse dust can be found in Skeletal remains, at the same depth the Old Wandmaker is in.
Once the Corpse Dust is given to the Old Wandmaker, the Hero will be rewarded with the choice of either a Battle Wand, or a Non-battle Wand.
Upon speaking with the Old Wandmaker:
Oh, what a pleasant surprise to meet a decent person in such a place! I came here for a rare ingredient - corpse dust. It can be gathered from skeletal remains and there is an ample number of them in the dungeon.
Being a magic user, I'm quite able to defend myself against local monsters, but I'm getting lost in no time, it's very embarrassing. Probably you could help me? I would be happy to pay for your service with one of my best wands.
Upon speaking with the Old Wandmaker without the Corpse dust:
Any luck with corpse dust, <insert class>? Bone piles are the most obvious places to look.
Upon returning to the Old wandmaker with Corpse dust:
Oh, I see you have succeeded! I do hope it hasn't troubled you too much. As I promised, you can choose one of my high quality wands.
