Lush trees rustle in the wind. Birds sing their songs with the morning sun, and the light shines upon flowers growing along the roads. A single path leads to a small house where a girl lives. Sophie is cheerful and bright, though somewhat absentminded. An ordinary girl you might find anywhere. However, she possesses one special power that the townspeople do not have. The mysterious power to mix several materials and create something entirely different: "Alchemy"... Unfortunately, she continues to fail at an essential skill, Synthesis. She reaches her limit, with no alchemy books to read, and no mentor to guide her. But one day, she encounters a mysterious book that can move and talk on its own accord. The book claims to be the "knowledge" of alchemy itself. This encounter becomes a new beginning for Sophieâ€¦a new adventure in a world where nothing is the same. Set against a vibrant background reminiscent of a medieval European town the Atelier series' 17th instalment follows the exploits of a young novice Alchemist who discovers she is the owner of an enigmatic volume imbued with a soul. This Mysterious Book seems to hold all the secrets to the art of Alchemy knowledge and it goes on to become Sophie's mentor. As Sophie improves her Alchemy skills throughout the story she unravels forgotten memories, and eventually sets out to uncover the strange tale of the book's origin. The game features a completely reformed worldview from earlier titles within the series, in addition to a new alchemy-centric system. Sophie is able to obtain ideas for recipes from activities such as harvesting, exploring, battling, or from events,and these ideas are used as a basis of improving her knowledge of alchemy. When she performs alchemy, the player is presented with various predetermined shapes representing the ingredients used, and arranges each shape on a puzzle board that represents the cauldron. This process involves visual trial-and-error, and if the shapes are arranged perfectly, the player receives a bonus. The materials selected affect the quality of the item synthesised.This system is intended to offer a high degree of freedom based on the player's own playstyle. Once the player gathers the required ingredients, the alchemy process involves a five-step process which consists of selecting a cauldron, applying ingredients, arranging shapes to receive bonuses, reviewing the bonuses acquired, and finally selecting which bonuses the player intends to keep. After crafting, the player is able to progress the story, in addition to equipping up to four categories of items using the "Dollmake" feature. The "Dollmake" feature allows the player to freely customise Plachta using costume items crafted by the player via alchemy. As the number of items crafted via alchemy increases, the possible customisation options widen.The game's new weather system affects how the game world changes based on the current time and weather; for example, items receive shop discounts and specific types of enemies appear at certain times and under certain conditions. The game is set in the small town of Kirchen Bell, a location with a warm atmosphere and occasional rainfall, during the dawning era of alchemy prior to it becoming a widespread art.Within the outskirts lies an atelier studio run solely by a girl named Sophie, who has a mysterious power that allows her to combine items together to form entirely different items. Without a mentor or reference guide to teach her, her alchemy attempts repeatedly fail time and time again. One day, however, she comes across a mysterious book that moves and talks by its own free will.Sophie's goal is to restore the book's memories and its former human form.
