# Uniqueness

Most NFT games sell in-game items as series that contain a limited number of items with the same properties. Our NFT minting process is a bit more complicated behind the scenes: we make the NFT item properties randomised to make them truly unique. Our system generates unique values for each attribute of the NFT item, making it almost impossible to mint two identical NFTs.

For example, a player chooses to mint a glove called "Iron Fist of Alchemy", that has the following default properties:

\


Physical damage: 80

Tactical damage: 44

Armor: 140

Attack speed: 14

Block rate: 4%

Durability: 574

The system first checks the rarity of the item which is 'Epic' in our case, meaning it will randomly assign a value between 85 - 100% range. The frequency of values between the two extremes is described by a Gaussian bell curve. The same applies to each of the property values, hence the probability that two NFTs are minted with the same combat properties is extremely low.
