In 224 of the Magical Age, the monster army in the north suddenly moved south and invaded the territory under the jurisdiction of the archmage. After hearing the news, the archmage was furious, and controlled his three strongest magic crystals to block the monsters, vowing to destroy the monster army. The three kinds of magic crystals have different attack effects, and flexible choices can make the game easier. Spell crystals can obtain gold coins and resources by knocking down monsters, and use them to upgrade crystals to make crystals more powerful.
