# Bound Item Merger

The **Item Merger** is a quality-of-life NPC designed to clean up and optimize your inventory. When you receive items from daily rewards, events, battle passes, VIP subscriptions, or cash shop packages, identical items with the same bound type or **\[NT]** (Non-Trade) tag often end up in separate inventory slots. The Item Merger scans your inventory and consolidates these duplicate stacks into single, compact stacks—instantly freeing up valuable inventory slots.

{% endhint %}

{% stepper %}
{% step %}

### Speak with the Item Merger

Visit the **Item Merger** at `prt_hq 117, 97`. The NPC automatically verifies your weight capacity and scans your inventory for eligible duplicate stacks.
{% endstep %}

{% step %}

### Select a Category

The main menu displays only categories that have mergeable items, complete with a live counter of how many inventory slots will be freed:

* **Merge ALL Eligible Stacks** *(Consolidates everything in one step)*
* **Account-Bound Items** `[AB]`
* **Character-Bound Items** `[CB]`
* **Guild & Party-Bound Items** `[GB]` / `[PB]`
* **\[NT] Non-Trade Items** `[NT]`
* **Unbound Regular Items**
* **Information & Help**
  {% endstep %}

{% step %}

### Choose Bulk or Individual Item Merging

Inside a category, you can choose to merge **ALL** items belonging to that category at once, or select a specific item to merge individually.
{% endstep %}

{% step %}

### Review the Preview Screen

Before any items are modified, a detailed summary displays:

* The exact item names and binding tags
* Total quantity to be consolidated (`X ea.`)
* Number of inventory slots that will be freed
* Total service fee (Default: 0 Zeny)
  {% endstep %}

{% step %}

### Confirm & Consolidate

Select **Confirm & Merge**. Your items will instantly merge into single stacks, freeing up your inventory space. A green confirmation notice will display the total number of slots saved.
{% endstep %}
{% endstepper %}

## Important Rules & Mechanics

{% hint style="warning" %}

* **Binding Isolation:** Items with different bound statuses will **NEVER** merge together. For example, an `[AB]` Account-Bound item and a `[CB]` Character-Bound item will remain in their respective separate stacks to protect your account bindings.
* **Stackable Items Only:** Only stackable consumables, tickets, passes, boxes, vouchers, and crafting materials are consolidated. Non-stackable equipment (weapons, armors, and accessories with individual refines or slotted cards) are safely ignored.
* **Weight Requirement:** Ensure you have enough weight capacity when speaking to the NPC so the inventory rearrangement can safely proceed.
* **Service Fee:** The standard service fee is set to **0 Zeny**. If a fee is ever enabled, the NPC checks your Zeny balance before proceeding.

## Frequently Asked Questions (FAQ)

<details>

<summary><strong>Will merging items change their bound status?</strong></summary>

**No.** An Account-Bound item remains Account-Bound `[AB]`, a Character-Bound item remains Character-Bound `[CB]`, and a Non-Trade item remains `[NT]`. Merging never alters item binding.

</details>

<details>

<summary><strong>Can I merge equipment like armors or weapons?</strong></summary>

**No.** Equipment items are non-stackable by design because each piece can hold distinct refine levels, cards, and random option bonuses.

</details>

<details>

<summary><strong>Why did I have duplicate stacks of the same bound item?</strong></summary>

Separate reward distributions (such as daily logins, battle pass tier claims, hourly rewards, and web shop packages) create new inventory entries upon receipt. The Item Merger cleans these up seamlessly.

</details>

<details>

<summary><strong>Is there a limit to how many times I can merge?</strong></summary>

**No.** You can use the Item Merger as often as you like whenever your inventory becomes cluttered.

</details>

<details>

<summary><strong>Where can I find the NPC?</strong></summary>

In the **Prontera Headquarters** at coordinate `prt_hq 117, 97`, or by using the `@itemmerge` / `@mergebound` commands.
