Atelier Yumia: Guide to Memory Alchemy and Land Synthesis

Author:Kristen Update:May 07,2025

One of the most intricate aspects of *Atelier Yumia: The Alchemist of Memories & the Envisioned Land* is the Synthesis mechanic, which is integral to nearly every facet of the game. Whether you're gathering resources or crafting weapons, understanding Synthesis can greatly enhance your gameplay. Here's how to maximize its potential.

Synthesis Types in Atelier Yumia

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

  • Regular Synthesis: This is conducted at an Alchemist’s altar and is essential for crafting weapons, armor, battle accessories, magical items, and materials needed for further Synthesis. Early in the game, you unlock the Atelier, where you can perform regular Synthesis at any time. Additionally, in areas where you can build, such as cleared manabound zones and campsites, you can construct a Simple Altar to enable regular Synthesis.
  • Simple Synthesis: Accessible through the radial menu outside of battle, this allows you to craft practical items like bandages, gauntlets for ziplines, and various repair kits for treasure chests, ladders, and more, provided you have the necessary resources.
  • Building Synthesis: Though not explicitly labeled as Synthesis, this mode is accessed via the radial menu on certain plots of land. Here, Yumia synthesizes items like storage chests and wall hangings, which the story often refers to as Synthesis.

How to Synthesize Equipment in Atelier Yumia

The regular Synthesis at altars is the most complex form. To craft a gun staff for Yumia, you'll first need to discover the recipe while exploring the game world. You can also upgrade existing recipes at a Recipe Recall Station using particles from mana fountains. Here's the process at an Alchemist’s altar:

  1. Select the type of gun staff you wish to create.
  2. Choose Synthesis Skills if they are unlocked in your skill tree.
  3. Select the initial Alchemy Core to start with:
    • Effects Alchemy Core: Enhances selected skills.
    • Quality Alchemy Core: Boosts the quality level of the completed item.
    • Trait Alchemy Core: Increases the number of Trait Crystal slots you can use.
  4. Fill the slots of each Alchemy Core with collected resources.
  5. Collect mana fragments to further enhance the item's quality.
  6. Synthesize the item to complete the process.

To craft powerful items early in the game, unlock Synthesis Skills from the skill tree as soon as possible. These skills provide boosts to damage and quality, and also allow item duplication, saving resources.

You can enhance the item further by adding resources to all three Alchemy Cores. Use the left or right bumper to navigate and fill slots in a specific core. Collecting mana fragments (yellow sparkles) for all cores significantly increases item strength, which is advisable for most items except quest-specific ones.

When selecting resources, choose those that match the element type of the slots, indicated by a blue outline. You can organize your resources from the submenu to prioritize higher-quality ones, though sometimes focusing on effects might be more beneficial.

If the complexity of the Synthesis mechanic feels overwhelming, opt for the auto-Synthesis feature after selecting your Synthesis Skills. This feature optimizes the crafting process, allowing you to create strong items capable of defeating the final boss on Normal difficulty with ease.

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