Although the Demon Radiance of a High-level Demon enhanced friend and foe alike, this enhancement was not without a cost. In essence, the power granted by the Demon Radiance was still an enhancement born from absorbing Evil Energy!
And this absorption was forced!
Typically, only those of an equivalent level of power could resist it.
Therefore, upon seeing the Knights and Wizards on their own side "strengthen" one after another, the three High-level Knights wreaking havoc on the battlefield felt no joy. Instead, with bloodshot eyes, they charged furiously toward the three Demons!
They had to eliminate these three creatures quickly and put an end to the Demon Radiance. Otherwise, if the fight dragged on, they would pay an incredibly steep price, even if they ultimately achieved victory!
