# How to craft Hourglass?
1. [**Workshop**](/game-economy/economy-components/workshops.md) **Rarity Restriction**
A **Workshop can only craft Hourglasses of equal or lower rarity**.
> A **Rare Workshop** can craft **Common, Uncommon, and Rare Hourglasses** but **not Epic or higher**.
2. **Two Crafting Methods**
* **Upgrade by Combining 3 Hourglasses**
* To craft an **Hourglass of higher rarity**, players need **three Hourglasses of the same lower rarity**.
* Additionally, they must own a **Workshop with a rarity equal to the target Hourglass**.
* Hourglasses must be **fully charged** and **not currently equipped**.
* **On-chain transaction required** to complete the crafting process.
**Craft from Materials**
* Requires **1 Empty Hourglass + Sand + Workshop**.
* The resulting Hourglass rarity is random but will be **equal to or lower than the Workshop rarity**.
* **Empty Hourglass** is obtained from:
* **Final boss chest rewards (Boss Challenge Mode)**
* **Bomb Pass rewards**
* **Sand** is obtained from:
* **Bomb Pass rewards**
* **Purchasable Sand packs in-game**
