"BECOME CORPSES, MINE ENEMY!" Vol bellowed at them, noticing their fear, and adding to it. "MY GOBLINS SHALL FEAST UPON YOUR BONES!"
His words didn't need to make sense. They didn't even have to be consistent. They just needed to contain within them enough aggression and sinisterness to make the enemy buckle. The fact did remain, after all, that Vol intended to summon some goblins if he could.
After his first attack, and his shouting, Nolan's men immediately backed away from him, and his heavy mace that seemed to fell three men every time it was swung.
That, of course, wasn't an optimal strategy, given the men to the side of them, who were just as hungry for their blood by now as Vol was.
"KILL THEM ALL!" Vol demanded, as soon as they showed their backs. He was surprised by the ferocity with which they responded to his command. It was his first time ever showing that level of command on a battlefield, and then men hungrily responded to it.
