Evolution Guide — How to Evolve Your Units

Step-by-step guide to evolving units in ATS, including material requirements and best evolution paths.

What is Evolution?

Evolution upgrades a unit's rarity tier (e.g., Epic → Legendary), boosting all stats and unlocking a new skill.

Evolution Requirements

You need: the base unit at max level, evolution materials from dungeons, and a Gem cost that scales with target rarity.

Best Units to Evolve First

Focus on your main DPS first. Tanjiro → Legendary Tanjiro is one of the most cost-efficient evolutions for mid-game players.

Material Farming

Evolution Stones drop from Dungeon floors 5+. Higher floors have better drop rates. Use XP Potions to speed up the leveling process.
