The sound of blows, coupled with the sight of something zipping out of the tornado at varying angles, circling around, ascending or descending, depending on the angle, before zooming back in prior to the next blow indicated that the fight was not over yet... Up until the tornado dissipated after several minutes. 

Izaroth floated opposite from Glacia, the sudden barrage of blows he'd dished out while Glacias was otherwise immobilized inside the Tornado's winds as well as having not only created the tornado and making sure he didn't get caught within it himself, coupled with his prior injuries having taken a toll on his stamina, and it was showing in the rate of his breathing. At this point, if Glacias hadn't been taken down, there was no chance in hell Izaroth would be able to muster any further might.
