# Mint NFT in EvoSim Universe: how the mechanics work

In EvoSim Universe you have the option to not only buy NFTs and use them to earn and level up, but also to mint (cross) assets. This way you can not only create new NFTs, but also get an eSIM box that contains a third NFT.

Let's take a closer look at what the minting process is, how it works, its cost calculation and what is the chance to get an eSIM box.

### Definition and features of Mint mechanics operation

Mint is a mechanic in EvoSim Universe that allows players to use two NFTs not involved in the game to create two new assets and a chance to get an eSIM box with a third Asset inside.

**Important conditions for committing Mint**

For Minting, you may use two NFTs not involved in the game with a Mint Count that is not equal to 7/7.

**An initial value of "1/7**" means that the NFT has not yet been used for minting.

**A maximum value of "7/7"** means that the item has been used the maximum number of times allowed.

Each time you use NFT to mint new instruments, the "Mint Count" value increases. For example, if this is the first time you have used an item for minting, it will change from "1/7" to "2/7", and so on up to a maximum value of "7/7".

**The mint feature is available for NFTs that are at level 5 or higher.**

**The main mechanic is the eSIM box**, the probability of getting it depends on the NFT's Luck score. Depending on the rarity of your NFT, as well as its level, the Luck score changes. That is, each NFT by rarity has a minimum and maximum chance of "Luck".

In the tables below you can read more about Luck depending on the level and rarity of your NFT.

### Common NFT

### Uncommon

### Rare

### Epic

### Legendary

**Important. **Once a rally has occurred, the Efficiency score ("Efficiency") does not worsen or improve, but remains as it was at the time of the rally.

**To calculate the cost of minting, you need to take the following data:**

**Please note!** When calculating the cost of minting, the Level Up cost from the first level to the current level of the NFTs that are involved in the minting process is taken into account.

For example, you have one Level 7 NFT and a second Level 8 NFT. In this case, you need to calculate the total Level Up cost of the first NFT from Levels 1 through 7 and the total Level Up cost of the second NFT from Levels 1 through 8.

**The formula for calculating the cost of minting is as follows.**

### eSIM box: the probability and what NFT inside can be obtained

The chance of getting an eSIM box from a minting is the arithmetic average of the Luck of the two NFTs you cross.

**For example, **you cross two Common NFTs of level five. The Luck value in this case is 20.3577%. To determine the chance of getting a box, do the following calculation:

**The next important **parameter is the rarity of the eSIM box that you can get as a result of mining. The rarity of the box depends on the rarity of the NFT assets you are minting.

With these changes, the minting process in EvoSim Universe becomes more understandable and predictable, giving players more control over their NFTs and increasing their chances of success.
