# Evolution

At the camp, the player will be able to evolve miners to migrate in [Rarity](/en/readme/recursos/miners/raritys.md). To carry out the evolution, the selected miner must have a star level of 3, and satisfy a burning condition that varies according to the miner selected as a result of the evolution. In addition to burning miners for evolution, it is also necessary to pay [$MSB](/en/readme/tokenomics/token/usdmsb.md) to complete the process.

To carry out the evolution, the player must select between 1 and 5 miners as burning material **(dummy, legendary and unique miners cannot be evolved or used as burning material)**. The quantity and rarity of burned miners determines the [$MSB](/en/readme/tokenomics/token/usdmsb.md) cost and success rate in evolution as shown in the table below.

{% hint style="warning" %}
**Attention**: always pay attention to the success percentage based on the selected miners, as the evolution attempt consumes [$MSB](/en/readme/tokenomics/token/usdmsb.md) what is necessary and burns the selected miners regardless of whether the evolution is successful or not. So use the strategy to succeed in the evolutions or save money and rely on luck. It's your choice...
