Atelier Yumia: The Alchemist of Memories & the Envisioned Land Synthesis Guide

by Hazel Mar 28,2025

One of the most intricate elements of *Atelier Yumia: The Alchemist of Memories & the Envisioned Land* is the Synthesis mechanic, which is intricately woven into every facet of the game. From the resources you gather to the weapons you craft, everything hinges on this system. Here’s how to optimize your use of it.

Synthesis Types in Atelier Yumia

In *Atelier Yumia*, there are essentially three types of Synthesis:

  • Regular Synthesis: Conducted at an Alchemist’s altar, this is used to craft weapons, armor, battle accessories, magical items, and materials necessary for further Synthesis. Early in the game, you unlock the Atelier, allowing you to return and Synthesize at any time. In buildable areas, such as cleared manabound zones or campsites, you can construct a Simple Altar to enable regular Synthesis.
  • Simple Synthesis: Accessible anytime outside of battle via the radial menu, this allows you to craft items like bandages, gauntlets for ziplines, and various repair kits for treasure chests, ladders, and more, provided you have the necessary resources.
  • Building Synthesis: Accessed through the radial menu in designated plots of land, this form of Synthesis involves creating storage chests and wall hangings, though it's not explicitly labeled as Synthesis in the game. The narrative often refers to it as such, so keep that in mind to avoid confusion.

How to Synthesize Equipment in Atelier Yumia

Synthesis in Atelier Yumia.

Regular Synthesis at altars is the most complex part of the system. For example, to craft a gun staff for Yumia, you first need to find the recipe during your exploration. You can also upgrade existing gun staff recipes at a Recipe Recall Station using particles from mana fountains. Once you have a recipe, follow these steps at an Alchemist’s altar:

  1. Select the type of gun staff you want to create.
  2. Choose Synthesis Skills if they are unlocked in the skill tree.
  3. Select the initial Alchemy Core to build upon.
  4. Choose between:
    • Effects Alchemy Core to enhance the selected skills.
    • Quality Alchemy Core to boost the quality level of the finished item.
    • Trait Alchemy Core to increase the number of Trait Crystal slots available for the item.
  5. Fill the slots of each Alchemy Core with collected resources.
  6. Collect mana fragments to further improve the item’s quality.
  7. Finalize and Synthesize the item.

To craft powerful items early in *Atelier Yumia*, it’s crucial to unlock Synthesis Skills from the skill tree as soon as possible. These skills not only boost damage and quality but also allow you to duplicate items, conserving resources.

You can enhance an item’s quality by adding resources to all three Alchemy Cores. Use the left or right bumper to switch between cores while filling slots. Collecting mana fragments (yellow sparkles around the Alchemy Core) for all three cores significantly enhances the item’s strength, which is advisable unless you’re crafting a quest-specific item.

When choosing resources, prioritize those that match the element type of the specific slots, identified by a blue outline. You can also organize your resources in the submenu to select higher-quality ones first, although sometimes prioritizing effects might be more beneficial.

If the detailed Synthesis process seems overwhelming, you can opt for the auto-Synthesis feature after selecting your Synthesis Skills. The game efficiently creates the best possible item, enabling you to tackle even the final boss on Normal difficulty without much hassle.

And that’s all you need to know to master the Synthesis mechanic in *Atelier Yumia*.
