# Evolutions

Robots in RoboHero have the ability to evolve, a transformative process that significantly enhances their capabilities. This evolution, however, is contingent upon fulfilling specific prerequisites:

* The robot must reach a certain level.
* It must be equipped with designated equipment.
* A specific amount of [**ASH**](/robohero-wiki/command-center/currencies/ash.md) and [**CRYSTALS**](/robohero-wiki/command-center/currencies/crystals.md) is required.

Evolution causes the gear equipped on a robot to vanish.

Each robot in RoboHero can evolve up to two times, allowing for three distinct stages of evolution. This process not only elevates a robot's stats but does so in a way that reflects its faction, class, and rarity. Moreover, the stat increase is further magnified by a multiplier associated with the robot's rarity.
