'Fighting for a long period of time is harder than I thought,' Kyle thought as he focused on healing from another injury he had received.
He had been fighting the Metal Elementals for several minutes already, and his focus had slipped.
While he was stronger than them, he was still human.
Meanwhile, the Metal Elementals were more like machines.
They were precise, methodical, and procedural.
Their programming wasn't perfect, but they never made mistakes with their imperfect programming.
Additionally, they constantly refined their programming.
When they realized that an attack didn't work, they changed their approach, and if that worked better, they would use that for a while.
Kyle's Ether was recovering faster than he was using it, but that was not true for his focus.
He hadn't been in such a long battle in his entire life, which was why he wasn't used to it.
