What about the extra foundation casting seals in Avalon?

Broken scrolls can be bought by hunting monsters or directly in prop shops. When the corresponding scroll fragments are collected, the Avalon King of Forging booklet can use these scroll fragments to synthesize a complete scroll in the forging factory.

When you have a complete scroll, you can go to the forge to forge new equipment. Scrolls can be obtained by synthesizing pieces of scrolls, divining from astrologers, or buying scroll treasure boxes in stores. Other materials needed for forging equipment may be obtained when fighting monsters and attacking barbarian camps.
