Rank 1 Reforge Available?

What does Rank 1 Reforge Available mean? Does that mean that it has Rank 1, but you'd need to use Credne Reforges in order to get lines on it? Or does that mean you can use a normal reforge, and it'll produce Rank 1 lines?

It means the item has a blank Rank 1 reforge, but that you to use a Fine Reforge Tool in order to "awaken" it (first line).
After that, you can use Credne's to add more "lines" and Fines to re-roll.

I see, good to know. Thanks!
