# NFT Craft

**NFT Craft system** is a key feature of the **Achiefy's** ecosystem. Users can find a wide range of **blueprints** (receipts) to craft unique and valuable NFTs by using energy and reagents earned through [challenges and other activities](/achiefy.io/explore-features/activities.md).

All NTFs from the blueprints collection are **pre-created by the Achiefy's team** and have a **limited quantity**. As soon all NFTs from a specific blueprint are crafted, the blueprint will become inactive, and this NTF will no longer be available for crafting.

The less identical NFTs were issued, the higher their value and the more [energy and reagents](/achiefy.io/explore-features/rewards.md) required for crafting.

Any user who has not enough [energy or reagents](/achiefy.io/explore-features/rewards.md) can **replace the missing resources with ACF tokens**. This system allows users who did not participate in challenges but are interested in NFTs to get crafting reagents **from players** by using [ACF tokens](/achiefy.io/explore-features/usdacf-token-utility.md). Users can also buy already crafted NFTs from players.&#x20;
