Gust is always changing how alchemy works in Atelier games. The synthesis system is in flux, with different means of piecing things together appearing almost every time. Sometimes, youll have more puzzling moments. The Mysterious series has entries with grids and ingredients having different colors and shapes to fill boxes. The Arland trilogy tended to have you picking items from lists. Atelier Ryza: Ever Darkness & the Secret Hideout changes up everything in the best sort of way, and the result is an entry where it is easier to become an invested alchemist.
