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.
