If he was only a fire elemental mage he might not have been able to fire it with any significant impact. It was already so big that if it touched anything it would explode.
But Esdras was not willing to compromise like that, he still had the wind element under his control. Tendrils of green wind began to form in front of his hand, like a vortex, and the speed kept increasing.
The vortex of wind became so sharp that it could cut through metal like a hot knife through butter. With a shout, he slammed the vortex into the fireball and fired it at the ant nest.
What he did not expect was that the wind vortex fused with the fireball as it was launched at such a speed that it created, tearing sounds in the air.
Fortunately, they were standing on a hill far away, this was why they were confident in escaping the blast from their current position. There was also no chance of tree branches triggering the explosion of the fireball early.
