Seberus was absolutely gobsmacked to learn that all 5,000 of Michael's allies possessed the same impenetrable shield as he did.
After all, the Absolute Unity Defense that Michael had was something that could defend against any and all kinds of spells.
No matter what element spell was thrown, as long as it wasn't cast by someone who was stronger than the wielder of the defense, then they wouldn't be affected by any spell.
"Yeah, they have it," Michael said matter-of-factly. "But theirs is called the Lesser Unity Defense. It's a weaker version than what I have. Since I'm a 4-star mage, any 4-star or lower magic spell would not do anything to me. But for them, if they're a 4-star mage, they can only protect themselves from spells that are 3-star or below."
Michael explained it with a faint hint of disappointment in his tone, as if it wasn't already one of the most powerful defenses that existed in this world.
