Even though each of those spells was only as strong as a True Mage's, it was still powerful enough to hurt Junova if it hit him directly. Not to mention, there were countless of them.
"Shit!"
Junova was overwhelmed by the onslaught of the lightning spells and was electrocuted.
His body glowed a golden light, and he spasmed repeatedly. And as if the lightning bolts received a command, they turned and headed towards Junova.
Of course, not all of them managed to hit him. Most of it scraped past his body, and only some of it hit him.
But some is a relative term. Some of the lightning means a lot of Shock Arc spells.
Junova became fried without any way to protect himself. He slowly lost his flight and fell to the city below.
Seeing the beautiful display of strength, the citizens below were terrified. Lawrend instantly cast an Arch Mage spell that was very hard to avoid.
