"Atelier Yumia" is a story about Yumia and her companions who face memories and, despite their hesitations, follow the path they believe in. Freely traverse the vast open world in all directions. The continent is an uncharted land where the player can use a wide variety of items and actions to make their way. Ranges and items offer an immersive variety of actions during combat. Real-time combat will put your decision-making skills to the test. Use two types of range in your strategy that change skills as you switch between them. Additionally, the synthesized items will transform into weapons such as swords and spears that can be used to attack. Items can be reused multiple times, so use them with confidence to get rid of enemies in your way. Weave mana to craft items. Manipulate the mana contained in ingredients to create new items based on recipes. The items you create will have powerful effects in a variety of situations, such as exploration and combat. An item's power depends on the ingredients used to synthesize it, so choose them carefully while analyzing the mana power they contain. You can use simple synthesis to create tools that open the way forward, as well as items that will be useful to you during combat and synthesis. You also have a building function at your disposal that allows you to create and then decorate bases. The Aladissian Empire once prospered on a certain continent, achieving remarkable growth thanks to alchemy that stopped the attack of other nations. However, as a result of a sudden and mysterious cataclysm, it came to an end. A few centuries later, alchemy became known as a dangerous art that brings destruction, and is considered "evil" and "taboo." Currently, the lonely alchemist takes her first steps in this unexplored and dangerous land. Her name is Yumia Liessfeldt, and after losing her mother in an accident three years earlier, she found out that she came from a family of alchemists, which raised many questions in her. Why was Aladiss destroyed? Why was alchemy banned? Is alchemy really bad? Convinced that the truth she is looking for lies on a fallen continent, Yumia embarks on a journey to learn its lost history.
