Dialogue
Hakan Derk Dialogue
You want to make quality weapons with the Black Stone NPC Knowledge Item?
This cave used to serve as a big furnace.
It doesn't work like that anymore,
but if you look around,
maybe you will find some clues.
That's all I can say for now.
Hakan Derk Dialogue (Alt)
If you do plan to go inside the cave,
beware of the Lava Tribe monsters.
Hakan Derk Completion
