EVOLUTION GUIDE

How to Evolve in Command An Army

To evolve a unit, check that unit’s current evolution requirement in-game, keep the needed duplicates or resources ready, then use the evolution option only after confirming the role still fits your four-unit army.

Short answer

Evolution changes the unit form. Requirements can vary by unit and update, so confirm the current in-game requirement before spending duplicates, Gems, or other resources.

Safe evolution checklist

  1. Open the unit you want to upgrade and read its current requirement.
  2. Keep useful duplicates until you know whether that unit can evolve or ascend.
  3. Compare the evolved role with your current four-slot army before committing.
  4. Recheck requirements after updates because progression details can change.

Do not mix up progression systems

Rarity stars, Star Limit, mastery, ascension and evolution are separate systems. A stronger-looking unit is not automatically better if it breaks your role balance or Star Limit plan.
