Neither warrior had used their spells during the battle. One refrained out of pride, while the other harbored far more sinister intentions.
From the start of the match, Damian had been subtly moving the runic circle of the invisible box closer to the pompous noble's throne-like chair. After injuring the champion knight, he finally activated it. Coincidentally, both the knight and the lord began screaming at the same time. Damian had expected the second-rank lord to have heightened enough senses to realize he was trapped in a confined space the moment it was activated. But the fat lord only noticed when he started struggling for breath.
