In an aerial battle, mobility was crucial, but the knights were forcing the beastmen on the defensive, taking away their main advantage.
Knights continued pouring out of the open portal like flies, so it was only a matter of time before they were overwhelmed by sheer numbers.
Everyone was busy and barely holding on to deal with the church troops, leaving the mages free to cast area-of-effect spells and explode several beastmen at once.
"The captain said reinforcements were on the way, but half of us will be dead by the time they finally arrive," Ash thought, hastily trying to come up with a plan to reverse the situation, but he realized there wasn't much he could do alone.
He was several times stronger than everyone around, maybe even stronger than the unit captain, but he couldn't change the tide of the battle alone.
A dozen lightning spears, fireballs, and arrows of light flew in his direction, interrupting Ash's thoughts.
