what line could i find the value for the shadowcrystal in chapter 5

In Chapter 5, the Shadow Crystal value appears to be tied to the secret boss reward line rather than a shop-style price or numeric value. The clearest line I found is that beating the Chapter 5 secret boss “yields the chapter’s Shadow Crystal,” and Seam’s Chapter 5 dialogue says the crystals contain “the power of lost dreams.”

What that means

• There does not seem to be a literal “value” listed for the Shadow Crystal in Chapter 5.

• The useful line for finding it is the secret-boss reward line: defeating the Chapter 5 bonus boss gives the Shadow Crystal.

• Community discussion also treats Chapter 5 as the final Shadow Crystal chapter.

Best answer

If you mean the line that tells you where it comes from, use: “Beating her yields the chapter’s Shadow Crystal.”

TL;DR: The Shadow Crystal in Chapter 5 is obtained from the secret boss, not from a stated market value, and the key line is that defeating the boss yields it.
