Sunny Crystals will first appear in Cole's shop. After buying all of them in stock, a scene will take place where the Ster Highlands are unlocked. They are used primarily to create Komets but can also be used to make weapons.
Cordelia will ask for two Sunny Crystals as one of the castle Front Quests anonymously. This request must be completed in order to complete Cordelia's events and get more of her requests. Esty may also request these from the castle as one of the regular Front Quests outside of Cordelia's flag.
Atelier Totori Edit
- "A crystal formed under bright sunlight. Charged with solar energy, it's almost blinding if you stare directly at it."
