At the front of the orcs' charging formation, their speed suddenly dropped sharply, while the Orc Wolf Riders in the rear, untouched by Concussive Shot, were still racing ahead. The front ranks were abruptly checked, almost coming to a halt, but the riders behind them could not brake their momentum in time and slammed straight into them.
