Dristel putting out the fire Toz left in his wake gave Toz enough of an opening to launch a fireball straight at Dristel. However, Toz wasn't the only one with good reflexes, and Dristel ducked under the spell. Usually, Toz would have been able to redirect the fireball to crash down on Dristel's back. But Dristel's attack forced him to dodge, and the fireball flew forward and collided with the net of chains.
Dristel had used mostly basic attacks, reinforced by martial energy, occasionally extending his spear with aura or throwing a PIercing Gale at Toz's face.
However, the attack he used after ducking under Toz's spell was a technique TOz hadn't seen before.
Dristel slipped the spear through his hands so that he held it at the end of the shaft with only one hand. He began dragging the spear just above the ground in a wide circle from almost right behind him, accumulating extraordinary amounts of martial energy and aura at the same time.
A little world-building (aka info dumping) to build tension for the finale :)
