Unite elemental heroes by merging tiles with fire blasts, ice barriers, and lightning strikes into upgraded champions. Collect experience by dispatching AI foes in auto-battle arenas; spend it to boost team stats—attack speed, crit chance, mana regen. Assemble squads—tank, healer, DPS—to tackle quests: lava caverns, frost citadels, storm towers. Boss fights demand synergy—freeze lava monsters to shatter them, amplify thunder to short-circuit guardians. Can your merged heroes conquer every domain and ascend the Hall of Heroes?
