The Synthesis mechanic in *Atelier Yumia: The Alchemist of Memories & the Envisioned Land* is a central and intricate part of the gameplay, connecting every resource you gather and every weapon you craft. Mastering this system can significantly enhance your gaming experience. Here's how to leverage Synthesis to its fullest potential.
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 used to craft weapons, armor, battle accessories, magical items, and materials essential for other types of Synthesis. Early in the game, you'll unlock the Atelier, allowing you to return and Synthesize at any time. Additionally, in certain areas like cleared manabound zones and campsites, you can build a Simple Altar to enable regular Synthesis on the go.
- Simple Synthesis: Accessible through the radial menu outside of battle, this allows you to craft practical items like bandages, gauntlets for ziplines, and repair kits for treasure chests and ladders, provided you have the necessary resources.
- Building Synthesis: Although not explicitly labeled as Synthesis, this mode, accessed through the radial menu on specific plots of land, involves Yumia creating storage chests and wall hangings, which the game's narrative refers to as Synthesis.
Understanding these different Synthesis methods can streamline your gameplay and resource management.
How to Synthesize Equipment in Atelier Yumia

Regular Synthesis at altars is the most complex aspect of the mechanic. For instance, crafting a gun staff for Yumia involves several steps:
- Find the recipe while exploring the world.
- Upgrade existing recipes at a Recipe Recall Station using particles from mana fountains.
- At the Alchemist’s altar, select the type of gun staff you want to create.
- Choose Synthesis Skills if they are unlocked in the skill tree.
- Select the initial Alchemy Core (Effects, Quality, or Trait) to build upon.
- Fill the slots of each Alchemy Core with collected resources.
- Collect mana fragments to boost the item's quality.
- Complete the Synthesis process to create the item.
To craft powerful items early on, unlocking Synthesis Skills from the skill tree as soon as possible is crucial. These skills provide significant boosts to damage and quality, and also allow for item duplication, conserving resources. Additionally, enhancing all three Alchemy Cores with resources can further improve item quality. Use the left or right bumper to navigate through the cores and collect mana fragments (yellow sparkles) to maximize the item's strength.
When selecting resources, prioritize those that match the element type of the specific slots, identifiable by a blue outline. Organizing your resources from the submenu to select higher-quality ones can be beneficial, though sometimes prioritizing effects might be more advantageous.
If the complexity of the Synthesis mechanic feels overwhelming, you can opt for the auto-Synthesis feature after selecting Synthesis Skills. The game excels at creating optimal items, making it feasible to tackle the final boss on Normal difficulty without much hassle.
With these strategies in mind, you'll be well-equipped to master the Synthesis mechanic in *Atelier Yumia: The Alchemist of Memories & the Envisioned Land*, available now.
