One of the most intricate elements in *Atelier Yumia: The Alchemist of Memories & the Envisioned Land* is the Synthesis mechanic, which is integral to nearly every aspect of the game. Whether you're collecting resources or crafting weapons, Synthesis plays a crucial role. Here's how to maximize its 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 required for Synthesis. Early in the game, you'll unlock the Atelier, allowing you to return and Synthesize at any time. In areas where you can build, such as cleared manabound zones and campsites, you can construct a Simple Altar for 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 repair kits for treasure chests and ladders, provided you have the necessary resources.
• Building Synthesis: Available only on specific plots of land through the radial menu, this involves creating storage chests and wall hangings. Though not explicitly labeled as Synthesis, the game's story often refers to it as such, so keep that in mind.

How to Synthesize Equipment in Atelier Yumia

Regular Synthesis at altars is the most complex form. To craft, say, a gun staff for Yumia, you first need to find the recipe during your exploration. You can enhance existing recipes at a Recipe Recall Station using particles from mana fountains. Here's how to proceed at an Alchemist's altar:

1. Choose the type of gun staff you want to create.
2. Select Synthesis Skills, if they're unlocked in the skill tree.
3. Choose the initial Alchemy Core to build upon:
   • 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 available for socketing.
4. Fill the slots of each Alchemy Core with your collected resources.
5. Try to gather mana fragments to further enhance the quality.
6. Complete the Synthesis process to craft the item.

To craft powerful items early in the game, unlock Synthesis Skills from the Synthesis section of the skill tree as soon as possible. These skills provide flat damage and quality boosts to your items, and they also allow you to duplicate items, saving resources.

To maximize item quality, add resources to all three Alchemy Cores. Use the left or right bumper to switch between cores while filling slots. Collecting mana fragments (yellow sparkles) for all three cores significantly boosts the item's strength, which is generally advisable unless you're crafting a quest item.

Don't overlook the importance of matching resources to the element type of specific slots, identified by a blue outline. You can organize your resources in the submenu to prioritize higher-quality ones, though you might want to focus on effects instead.

If you prefer a simpler approach, use the auto-Synthesis option after selecting Synthesis Skills. The game excels at crafting the best possible item, enabling you to tackle the final boss on Normal difficulty with relative ease.

With these tips, you're well-equipped to master the Synthesis mechanic in *Atelier Yumia*.
