After the potion run and the obvious revitalization of the Alliance of Kingdom's troops, the Tribe of Death's forces halted in their assault for a moment. It was only for barely more than an instant. But the fact that the Tribe of Death's forces showed any reaction at all to the Alliance of Kingdoms defenses improving was all General Scoll needed as confirmation. That reaction wasn't planned. If it was, the Tribe of Death should have gone into theater instead of war.
It was actually still too early to confirm if his hopes had come true. But General Scoll trusted his ability to read the flow of combat. And he also trusted his knowledge. Though it was practically common knowledge for everyone on the battlefield that nothing daunted the Tribe of Death. They were immovable in front of death, and yet they never stopped moving. That was the kind of enemy the Tribe of Death was.
