Onslaught of basic mana bolts

"I command thee, kneel!" 

The leader of the dragon hunters shouted while raising his staff with likely a dragon's beating heart to the skies. 

And in the meantime, I intensified the bombardment of my mana bolts, erasing both the only remaining ranger subordinate of his along with the one that stood back to support the rest. 

As it turned out, targeting the supporter, in particular, was a great idea. The two melee users that only turned more frantic with their attack ever since the onslaught started managed to avoid death only thanks to the set of barriers that protected them from my attacks. 

A set of barriers vanished the second the dragon hunter of a supporting role ceased to exist, along with several body parts of the last two of the soldiers in the instant that followed the supporter's death. 

"How…" the leader of the now deceased group stared blankly at the situation right in front of him.
