Thank you for providing the code, I appreciate it. This code is for the Summoners War: Chronicles April Fool's event, and it can be redeemed in-game by entering "APRFOOL4" in the event code section. Once redeemed, players will receive various rewards such as mana stones, crystals, and energy. This code is only available for a limited time, so players should make sure to redeem it as soon as possible.
