# Collectible Synthesis

Collectible Synthesis feature ilets players upgrade specific collectibles into higher-quality versions. The system supports merging same-type, same-rarity items, with a Priority mechanic that increases the chance of boosting rarity.

## How It Works

Players can select a collectible as the Main Component and consume other materials of the same type to enhance its quality.

### Step 1: Select Main Component

Tap an item in your Inventory — the first item tapped is set as the Main Component for synthesis.

### Step 2: Add Materials

Slot in 10 items of the same type as the Main Component to proceed with ascension.

Note: All materials must be the same type as the Main Component — no mixing allowed.

### Step 3: Confirm & Ascend

Once all materials are in place, hit \[Confirm] to start the ascension.

If successful, your Main Component upgrades to a higher quality version — good luck!

## Quality Ascension Rules

* The ascended collectible will increase by +1 quality tier.
* If the Main Component is SR, it will ascend to UR quality after synthesis.

## Priority Mechanism

The Priority tag affects synthesis rules:

**If the Main Component comes with a Priority tag:**

* All 10 materials must also be Priority items.

**If the Main Component comes without a Priority tag:**

* Materials can be a mix of Priority and non-Priority items.

#### How to Get or Keep Priority 

* Regardless of success or failure, the final product always increases in quality.
* Whether the resulting item retains or gains the Priority tag is determined by system probability.
