Master of Mining 5

You've come a long way, friend. This is the last challenge I have for you now. Bring me 1 Magic Powder (Black).

Magic Powder (Black) can be obtained by refining Dark Crystal Ore or Black Crystal Ore. Since they are rather rare, it will require some patience. I wish you luck.

You must train your skills diligently. Come back when you have the time.

I don't think you have everything I asked you to get. Come back when you have everything.
