“That’s not cheating, unfortunately.
In case you’re wondering, I can do something like this; [Level 4 Dark and Water Compound Magic: Prohibition].

That’s it.
This will disable your fireballs for three minutes from now.”

“You sealed my fireballs? There’s no such magic that can seal magic! I feel sorry for your bluff! Hm? Arey? Arerey? Why is there no fireball?”

“As I told you, I disabled it for three minutes.”

This [Darkness/Water Compound Magic: Prohibition] was one of the most powerful and high-end magic.

The Dissolution Magic and the Prohibition Magic… I feel nostalgic as these two were the signature magic that represented my youth.‎
