#### 🔪 Sharpness

* **Affects the amount of $HERO earned** during battles.
* Decreases by 1 point every time the hero wielding the weapon is unstaked.
* Can be restored to **MAX Sharpness** at **The Blacksmith** using $HERO.

***

#### 🛠️ Durability

* Does **not affect performance** directly.
* Decreases by 1 point every time the hero wielding the weapon is unstaked.
* If **Durability = 0**, the weapon becomes unusable until repaired.
* Can be restored at **The Blacksmith** using $HERO.

### The Blacksmith

The Blacksmith allows players to **maintain** and **extend the life** of their weapons.

| Action      | Effect                                      | Cost Formula                                                         |
| ----------- | ------------------------------------------- | -------------------------------------------------------------------- |
| **Sharpen** | Restores weapon to MAX Sharpness            | `(daysSinceS2 * weaponRarityCoefficient * 100) / (20 + daysSinceS2)` |
| **Repair**  | Restores weapon to MAX Durability (if at 0) | Same as Sharpen                                                      |

> **Note:** Both Sharpening and Repairing cost scale with time and rarity, encouraging early and strategic upgrades.

#### 🎰 Remixing Weapons (Gacha Remixer)

Remix multiple lower-tier weapons to **create a single higher-tier weapon**. Remixing always returns one weapon of **equal or better rarity**.

{% hint style="info" %}
Cost to Remix = ((daysSinceS2 \* 240) / (20 + daysSinceS2) + 100) \* weaponRarityCoefficient
{% endhint %}

| Remix Inputs | Upgrade Probabilities | Upgrade Probabilities | Upgrade Probabilities |
| ------------ | --------------------- | --------------------- | --------------------- |
|              | **+0 Tier**           | **+1 Tier**           | **+2 Tier**           |
| 2 Weapons    | 30%                   | 70%                   | 0%                    |
| 3 Weapons    | 5%                    | 94%                   | 1%                    |
| 4 Weapons    | 0%                    | 95%                   | 5%                    |
| 5 Weapons    | 0%                    | 90%                   | 10%                   |

{% hint style="info" %}
Please note, the 2-Weapon Remix will launch with a 70/30 success/fail rate, but phase to a 60/40 success/fail rate over the course of 5 days with a 2% change per day.&#x20;
{% endhint %}

> ⚠️ **Legendary ➝ Mythical Remix Rule**
>
> * The **only way to obtain a Mythical weapon via remixing** is by combining **3 Legendary weapons**.
> * This special remix has a **50% chance** to upgrade to **Mythical.**
> * Cost uses the same formula as above

| Input               | Result                           | Chance | Cost Formula |
| ------------------- | -------------------------------- | ------ | ------------ |
| 3 Legendary Weapons | Mythical (50%) / Legendary (50%) | 50%    | Same formula |
