Lucifer thought of a way to turn the tide against the sky beasts. He decided to unleash his most recent and powerful spell: Thunder Rain. Sitting in a meditative stance, he began to call upon his mana, connecting with the atmosphere around him. With focused concentration, he formed a bond with the ambient mana, allowing him to manipulate the weather.
As he deepened his connection, the skies above the battlefield began to darken. Thunderclouds gathered, swirling ominously above the attacking beasts. Lucifer's mastery over his lightning affinity came into play as he infused his mana into the clouds. The air crackled with energy, and an intense anticipation built up among the defenders of the Lava Kingdom.
