Kothar struggled against the Aemos soldier's grip, but he couldn't break free. Thanks to his Plasma Blade, Kothar hadn't had to face the Aemos in the realm they specialized in the most, raw physical strength.
The soldier growled and grunted as he wrestled Kothar to the ground, while he did so, Kothar realized at the angle his arm was trapped at, his Plasma Blade would be ineffective.
So, favoring the stronger shock that it would provide, he cast his Ball Lightning spell, flicking it out with his left hand, and then manipulating the mana, so it curved around the soldier's back, and struck him in the head.
"Bzzzt!" There was the loud buzz of Kothar's spell hitting home, and then the smell of burnt flesh filled the air, and the soldier went limp, his brain fried to crisp by Kothar's.
