Evolve & Upgrade
Heroes evolve and unlock more potential as they gain new star levels. Full power is achieved at 12 stars.
Material Heroes are required alongside ASG to evolve a Hero. The more stars the evolving Hero has, the more and higher-quality materials are needed.
Material Heroes are burned and removed from circulation.
Level cap is limited by Star and the level 250 cap is unlocked as Hero reaches 12 stars.
