# Enchant grade system

<figure><img src="/files/0tWXKXtU5dUXgSBjGUOT" alt=""><figcaption></figcaption></figure>

## 1) <mark style="color:$info;background-color:$info;">Overview</mark>

Enchant Grades add a progression layer **on top of refining**. You keep refining your weapon like normal, **then** improve its *grade* to boost the value of those refines and, at **Grade A**, unlock extra per-refine perks.

**Key points**

* Grades run **D → C → B → A**.
* You can upgrade grade at the **Enchant Grade Master (Haldier)**.
* Your current grade is shown as **\[D] / \[C] / \[B] / \[A]** in menus/tooltips.
* Only **Grade A** grants *extra bonuses per refine* (see Section 5).

## 2) <mark style="background-color:$info;">How Enchant Grades Work</mark>

* Each eligible item (mainly **weapons**) starts at **Grade D**.
* You can rank it up to **C, B, and A** using materials and Zeny.
* Grades affect:
  1. **Refine scaling** (how much benefit you get from each refine level).
  2. **(Grade A only)** Extra bonuses that scale with your item’s **refine** and **weapon level**.

> If you see the grade tag like **\[A]** next to the item name or in the UI, that item is already Grade A.

## 3) <mark style="background-color:$info;">Rank Up Your Gear</mark>

1. <mark style="color:$primary;">**Find Haldier**</mark> (Enchant Grade Master) in the main town.
2. Choose the item you want to upgrade.
3. Confirm the material & Zeny cost (varies by grade step and item).
4. If the attempt **succeeds**, your item’s grade increases (D→C, C→B, or B→A).

## 4) <mark style="background-color:$info;">Grade Bonuses at a Glance</mark>

Most of the magic happens at **Grade A**, which adds *per-refine* perks. For **D/C/B**, expect standard refine behavior (the exact multipliers are server-configured).

**You always keep your normal refine benefits**; Grade A just layers extra bonuses on top.

## 5) <mark style="background-color:$info;">Grade A — Per-Refine Bonuses</mark>

At **Grade A**, your weapon gains **extra bonuses that scale with refine level** and **weapon level**.

> "Per refine" means the bonus is **multiplied by your current refine level**.\
> Example: If a perk says **+3% per refine** and your weapon is **+10**, that’s **+30% total** from this perk.

#### <mark style="color:purple;">Weapon Level rules for Grade A</mark>

| Weapon Level | Extra Critical per refine | Extra Damage vs **all elements** per refine | Attack speed per refine |
| ------------ | ------------------------: | :-----------------------------------------: | :---------------------: |
| **WLv 1**    |               **+2 Crit** |         (no extra elemental damage)         |     (no extra aspd)     |
| **WLv 2**    |               **+3 Crit** |      **+1%** (physical **and** magical)     |     (no extra aspd)     |
| **WLv 3**    |               **+5 Crit** |      **+2%** (physical **and** magical)     |        +1% (aspd)       |
| **WLv 4**    |               **+8 Crit** |      **+3%** (physical **and** magical)     |        +2% (aspd)       |

* “Crit” here is the **value you see on the character window**.
* "Damage vs all elements" applies against **Neutral, Water, Earth, Wind, Fire, Holy, Dark, Ghost, Poison, and Undead** targets, for both **physical** and **magical** damage.

**Quick examples**

* **WLv 4 Grade A +10** → **+80 Crit** and **+30% damage vs all elements** from Grade A perks.
* **WLv 2 Grade A +12** → **+36 Crit** and **+12% damage vs all elements** from Grade A perks.
* **WLv 1 Grade A +9** → **+18 Crit** (no elemental bonus).

> These bonuses are **in addition** to any other refine effects, cards, enchants, or skills.

## <mark style="color:purple;">Refine Grades  - How the Bonus ATK Works</mark>

> The Grade on your weapon *multiplies the ATK you get from refine*.\
> For **Weapon Level 1** (WLv1), base refine gives **+2 ATK per +1**.\
> Grades add extra % on top of that base:
>
> * **Grade D** = **+50%** more refine ATK
> * **Grade C** = **+150%** more refine ATK
> * **Grade B** = **+250%** more refine ATK
> * **Grade A** = **+350%** more refine ATK

### 1) <mark style="background-color:$info;">The Base: Refine ATK (WLv1)</mark>

* By default on this server, **WLv1** weapons gain **+2 ATK per refine**.
  * Examples with **no grade**:
    * **+1** → 2 ATK
    * **+5** → 2 × 5 = **10 ATK**
    * **+10** → 2 × 10 = **20 ATK**

> This “base refine ATK” is what the Grade multiplies.

*

```
### 2) <mark style="background-color:$info;">The Grade Bonus (WLv1)</mark>
```

```
Grades add **extra % of the base refine ATK**.\
Formula (showing the _extra_ and the _total_):

* **Grade D (+50%)**
  * **+1**: 2 + 50% = **3 ATK** (2 + 1)
  * **+10**: (2 × 10) + 50% = 20 + 10 = **30 ATK**
* **Grade C (+150%)**
  * **+1**: 2 + 150% = **5 ATK** (2 + 3)
  * **+10**: 20 + 150% = 20 + 30 = **50 ATK**
* **Grade B (+250%)**
  * **+1**: 2 + 250% = **7 ATK** (2 + 5)
  * **+10**: 20 + 250% = 20 + 50 = **70 ATK**
* **Grade A (+350%)**
  * **+1**: 2 + 350% = **9 ATK** (2 + 7)
  * **+10**: 20 + 350% = 20 + 70 = **90 ATK**

> **Tip:** The % is applied to the base refine ATK, not to your total ATK stat.\
> In practice, the server calculates with integers (fractional results are truncated).

## 7) <mark style="background-color:$info;">FAQ</mark>

**Q. Where do I see my current grade?**\
A. Look for the grade tag **\[D] / \[C] / \[B] / \[A]** next to the item name or in the Enchant Grade UI.

**Q. Do I lose refines when I rank up?**\
A. No. Ranking up changes the **grade**, not the refine level.&#x20;

**Q. Does the Grade A elemental damage work on magic too?**\
A. Yes. The “damage vs all elements” perk applies to **both physical and magical** damage.

**Q. Does this stack with cards, elemental converters, and skills?**\
A. Yes. Grade perks stack with your usual builds and gear.

**Q. Which items can be graded?**\
A. Most **weapons**. the NPC menu will only show eligible items.
