# Minions Upgrading

You can get more battle powers by upgrading your NFTs.

Upgrading condition is to burn each 2 of them to get higher level NFTs.

|  Upgrade  |    Burn    | Success Rate |
| :-------: | :--------: | :----------: |
|   Common  |      -     |       -      |
|  Uncommon |  2 Common  |     100%     |
|    Rare   | 2 Uncommon |      80%     |
|    Epic   |   2 Rare   |      30%     |
| Legendary |   2 Epic   |      10%     |

{% hint style="success" %}
Each upgrade will consume $1 worth of TWI or STWI

If the upgrade is successful, a minion with a higher rarity will be minted; if the upgrade fails, only a minion of the same rarity will be minted.
