# Weapon Mending

## Overview

<figure><img src="/files/fQCSlqyiAMzGPKHVK219" alt=""><figcaption></figcaption></figure>

[Weapons](/items-and-assets/weapons.md) have two traits that require regular maintenance: **Sharpness** and **Durability**.\
As your Hero returns from battles, these traits will gradually wear down—reducing effectiveness or rendering the weapon unusable.

Restore both traits at **The Blacksmith** using **$HERO** to keep your weapons battle-ready and maximize reward potential.

> 💡Sharpness and Durability **does not decrease** after battling **Bosses**, but drops by **2** if the Hero **dies**

## Weapon Mending Mechanics

Maintaining your Hero’s weapons is essential for maximizing rewards. The Blacksmith lets you sharpen and repair weapons to keep them battle-ready and effective.

&#x20;Both Sharpening and Repairing cost scale with time and rarity, encouraging early and strategic mending.

> All weapons are minted at max sharpness and durability.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.onchainheroes.xyz/archive/weapon-mending.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
