He didn't even register what the other wisp said to him, anger already boiling up inside him. Why was his hatred so persistent? As a verse dictates "Do to others as you would have them do to you.". He had done a number of things in his life so he shouldn't be surprised if a similar string of bad events happen to him but even as he understood this his anger couldn't be quelled.
He caught a glimpse of the fairy approaching from afar. After looking at each other the fairy seemed to have come to a realization and it started to charge at him.
"Don't screw with me you humanoid flea.(Curse Word I)"
To him, it looked like the whole purpose of those creatures was to make fun of humans. Small humanoid things with insect wings? Always flying around playfully? A complete mockery and abomination.
Charging up his projectile he thought about the time when he charged 2 of them and still couldn't manage to hurt a single monster. Primitive weaponry with no technological boost to make it viable. Maybe if he concentrated the spherical projectile and shaped it like a bullet. But would the shape affect the velocity or the piercing capabilities of the energy projectile? Maybe if he could crystallize it, like the crystals spread all throughout the cave, then maybe...but that would also require to give it a spin to stabilize the bullet. And that would also need to adjust his aiming accordingly in long range shots but the insect wasn't too far away for that to matter anyway.
Putting all these thoughts into his attack, he fired what he hoped to be something resembling a bullet.
