Sigil of Will-Power

Description
A small badge with a half cut ruby and the other half a sapphire, both in the shape of a curved tear drop wrapped around the other. Well, at least you think the jewels are a ruby and sapphire. They seem a bit off to the touch for gems, and don't seem to sparkle as well as they should.

Effect
Proof of clearing the Will-Power Temple. Expands Amber's shop inventory and adds the ability to explore the Will-Power Temple as a dungeon.

Obtaining
Defeat either Himika or Mizuko for the first time.
