For magic crafting, your skill needs to be above a certain grade.

You need to craft Processed Silver Soul Stone.

I don't know if you'll be able to craft it at your... proficiency, Player.

To craft the Processed Silver Soul Stone, you need to prepare enough Silver Crystal Soul Stone. Think you can do it?

Player: Accept

Did you manage to craft the Processed Silver Soul Stone?

Let me see.

Player: “Will these do?”

Yes, that’s everything we need.

And they’re good quality, too.

Player: “Glad to hear it.”

Tsk tsk, Daeva. You know what they say about curiosity.

You'll find out once we deem you worthy enough, Player.
