The power of the Ice Maxim exceeded Merlin's expectations. The very moment his hand wrapped around the Ice Maxim, everything seemed to come to a complete stop.
If he was an ordinary person, it would be futile to even attempt to seize the Maxim as it would be a suicide mission. Even without anyone's control, the Maxim contained insurmountable power. The fact that this Maxim was strong enough to suppress the Ice Goddess for thousands of years by itself, was a testament to its power.
Moreover, an Honored Legend's Maxim was not the same as ordinary Maxims. In order for a Spell Caster to be known as an Honored Legend, he must first be able to produce an ultimate Maxim, namely the strongest Maxim of one of the elements!
Only after producing an ultimate Maxim, the Spell Caster was worthy to become an Honored Legend. This also meant that their ability to control the particular element had surpassed the gods.
