Timothy absolutely dominated his six opponents, he had the upper hand, and performed accordingly. However, he was still far away from completing the mountain of tasks that he was stacking above his shoulders!
For example, if he ran into an opponent that was more powerful than him, he'd be dead, so he was working on the not-dying part. He degraded one of the fresh corpses in front of him, took its skull, and started shaping it into a helmet, because quite frankly, he didn’t want to risk getting hit on the head by anything physical.
Dark mages didn’t often use physical means to attack their opponents, but he didn’t want to take any chances! Since the pyramids had depleted most of his mana pool, he had to take various measures of protecting himself from danger!
