Arrogant Turtle was an Authority Magic Isaac had developed at Tier Three, based on his Fantasy Authority of [Positive Infinitesimal]. It provided a defensive capability similar to the concept of "limitless"—any attack unable to break through his Authority's defense would only get closer and closer to Isaac, yet never manage to touch him.
It was a Defense Magic that looked incredibly perilous but was, in reality, completely overpowered.
When this Magic was upgraded to an Authority Magic, its defensive power increased further, and it also gained offensive applications. It could be used to restrain an enemy by infinitely expanding the distance between them and their surroundings, creating an effect similar to time stoppage.
'Arrogant Turtle?' Morgan quickly recognized it.
