Desire for Better Weapons

Customers are lining up these days, which means they like my work. But I have no plan to be content and settle down. It will only hinder my advancement as a craftsman. So... I need to keep improving, and that's why I came up with this idea. Black Stone. That stone has some surreal power, from what I hear. The thing is... I have never tried using that stone. I don't even know what it actually is! I want to run around and ask people about it, but I can already see that Dwarf next to me giving me THE LOOK. You. Learn something about the Black Stone for me. Squeeze out some juicy information.

Don't run around announcing it to the entire town! Be discreet! Secretive! Hush-hush!

Black stone ... Funky, funky stuff, I tell you. So, how am I supposed to use that?
