Beastification
The technique Greg employed wasn't rooted in energy manipulation but an unconventional application of sculpting, as explained by Howard.
He began experimenting with this method, using mana for precise sculpting to form a thin, yet durable shell, then transforming mana within into highly condensed and unstable light and heat, releasing it in a directed burst.
When the dosage was right, light and heat too could become deadly weapons.
The impact of Greg's attack might not have been massive, but its effect on Soma was undeniably significant.
The intense flash of light, exploding at a moment when Soma's attention and senses were sharply focused, left nothing in his vision but blinding white.
Unable to see anything momentarily disrupted Soma's combat capabilities significantly.
Though this wasn't a complex Blinding Spell, Greg felt that in some scenarios, this simple burst of light was even more effective.
