Why Redeem Codes Matter in Idle Heroes
Redeem codes hold significant value for both new and veteran players. Free Gems accelerate key summoning cycles, Heroic Summon Scrolls increase the chance of acquiring elite heroes, and Core of Transcendences support the pursuit of top-tier Transcendence units.
