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

Author: Aria Apr 17,2025

The Synthesis mechanic in *Atelier Yumia: The Alchemist of Memories & the Envisioned Land* is a central and intricate part of the gameplay, intertwining with resource collection and crafting. To truly master the game, understanding and optimizing your use of Synthesis is crucial. Let's dive into the different types of Synthesis and how to maximize your equipment crafting.

Synthesis Types in Atelier Yumia

In Atelier Yumia, you'll encounter three distinct types of Synthesis:

  • Regular Synthesis: Performed at an Alchemist's altar, this is essential for crafting weapons, armor, battle accessories, magical items, and materials required for other Synthesis processes. Early in the game, you unlock the Atelier, which serves as your primary Synthesis hub. Additionally, you can construct a Simple Altar on cleared manabound zones or campsites for convenient access to regular Synthesis.

  • Simple Synthesis: Accessible anytime outside of battle through the radial menu, this allows you to craft utility items like bandages, zipline gauntlets, and repair kits for treasure chests and ladders, provided you have the necessary resources.

  • Building Synthesis: Although not labeled as Synthesis, this mode, available on certain plots of land, involves crafting storage chests and wall hangings. The game often refers to this as Synthesis, so keep that in mind to avoid confusion.

Regular Synthesis at altars is the most complex aspect of the mechanic. Crafting a gun staff for Yumia, for instance, involves several steps:

  1. Find the Recipe: You'll need to discover the recipe while exploring the world. You can also upgrade existing recipes at a Recipe Recall Station using particles from mana fountains.

  2. Select the Gun Staff: Choose the type of gun staff you want to create at the Alchemist's altar.

  3. Select Synthesis Skills: If you've unlocked Synthesis Skills in the skill tree, select them to boost your item's damage and quality.

  4. Choose the Alchemy Core: Start with an initial Alchemy Core and decide whether to focus on:

    • Effects Alchemy Core to enhance selected skills.
    • Quality Alchemy Core to increase the item's quality level.
    • Trait Alchemy Core to add more Trait Crystal slots.
  5. Fill the Slots: Add collected resources to the slots of each Alchemy Core. Use the left or right bumper to switch cores and add resources.

  6. Collect Mana Fragments: Gather yellow mana fragments around the Alchemy Core to further boost the item's quality.

  7. Synthesize the Item: Complete the process to create your item.

To craft powerful items early in the game, unlock Synthesis Skills from the skill tree as soon as possible. These skills not only enhance your items but also allow you to duplicate them, conserving resources. Additionally, matching resources to the element type of specific slots (indicated by a blue outline) and prioritizing higher-quality resources can significantly improve your crafted items.

If the detailed Synthesis process seems daunting, you can opt for the auto-Synthesis feature after selecting your Synthesis Skills. This option simplifies the process and still results in strong items, allowing you to tackle even the final boss on Normal difficulty without much trouble.

And that's everything you need to know to leverage the Synthesis mechanic effectively in Atelier Yumia.
