Atelier Yumia: Guide to Memory Alchemy and Land Synthesis

by Penelope Jun 02,2025

One of the most intricate aspects of Atelier Yumia: The Alchemist of Memories & the Envisioned Land lies in its Synthesis system, which is deeply intertwined with nearly every facet of the game. From the resources you gather to the weapons you forge, everything revolves around this mechanic. Let’s dive into how to master it.

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

  1. Regular Synthesis: Conducted at an Alchemist’s altar, this is where you craft essential items like weapons, armor, battle accessories, and magical pieces.

  2. Simple Synthesis: Accessible via the radial menu, this allows you to create items like bandages, gauntlets for ziplining, and repair kits when needed.

  3. Building Synthesis: Found in the building mode, accessible through the radial menu, this lets you create storage chests and wall hangings—though it’s not labeled as Synthesis, it functions similarly.

To begin crafting weapons, armor, and other gear, you’ll need to utilize the regular Synthesis mechanic at an Alchemist’s altar. Early in the game, you’ll unlock the Atelier, which serves as your primary Synthesis hub. Additionally, certain areas allow you to build and place a Simple Altar for quick access to regular Synthesis.

Accessing Simple Synthesis is straightforward—it’s available anytime outside of battle through the radial menu. Meanwhile, Building Synthesis is restricted to designated plots of land scattered across the map.


How to Synthesize Equipment in Atelier Yumia

The regular Synthesis mechanic at altars is undoubtedly the most complex part of the process. For instance, to craft Yumia’s iconic gun staff, you’ll first need to discover the recipe during your explorations. Upgrading existing recipes can be done using particles found at mana fountains at a Recipe Recall Station.

Here’s a step-by-step guide to crafting equipment:

  1. Select the Item Type: Choose the gun staff or another piece of equipment you wish to create.
  2. Choose Synthesis Skills: If you’ve unlocked Synthesis Skills from the skill tree, select them to enhance the item’s stats.
  3. Select Initial Alchemy Core: Begin with the base core.
  4. Add Effects: Enhance the item’s abilities with an Effects Alchemy Core.
  5. Quality Alchemy Core: Increase the overall quality of the item.
  6. Trait Alchemy Core: Boost the number of Trait Crystal slots available.
  7. Fill Slots: Populate the cores with resources you’ve collected.
  8. Collect Mana Fragments: Gather mana fragments (yellow sparkles) to maximize quality.
  9. Finalize: Once complete, Synthesize the item.

To excel early on, prioritize unlocking Synthesis Skills as soon as possible. These provide flat boosts to damage and quality, allowing you to duplicate items and conserve resources. Additionally, adding resources to all three Alchemy Cores enhances the item’s strength. Press the left or right bumper while filling slots to do so effectively.

When gathering resources, ensure they match the slot’s elemental type (indicated by a blue outline). Organizing resources in the submenu helps select higher-quality options, though prioritizing effects may sometimes be beneficial.

If Synthesis proves overwhelming, opt for the auto-Synthesis feature after selecting Synthesis Skills. The AI will craft the optimal item, making boss battles—especially on Normal difficulty—manageable.

That’s all you need to know to harness the Synthesis mechanic in Atelier Yumia. Dive in and enjoy the alchemical journey!
