Water Shield, a level 2 cantrip, created a defensive force field through the arrangement of water elements.
This was a cantrip Angel had researched during this period. Among defensive cantrips of all branches, this one was considered among the weakest in terms of defense. However, it had a special use: Water Shield possessed an extremely high defense coefficient against water pressure. While maintaining Water Shield, one would not be disturbed by pressure even in the deep sea.
Back then, when so many people had been thrown into the Purification Garden, during the final Sea of Purification, many low-level apprentices had only been able to move beneath the sea by relying on Water Shield.
At the time, Angel had relied on the Purification Field to survive underwater. However, the Purification Field was not a cantrip Angel himself knew; it had been attached to a hat. If that hat had been destroyed underwater, he would have had to endure the terrifying pressure of the seabed.
Thus, after leaving the Sea of Purification, Angel had begun deliberately, or otherwise, to learn Water Shield.
However, plans could not keep up with change. Not long after Angel left the Sea of Purification, he went to Witch Town in the Nightmare Realm because of an accident. Then his right hand mutated and fused with the Projected Bloodline. Although the Projected Bloodline had not granted him any special abilities, it had greatly strengthened his physical body. With a few defensive cantrips and his own bodily strength, withstanding deep-sea pressure was no longer a problem.
So Angel later gave up learning Water Shield.
Now that he wanted to train in water cantrips across branches, he could not find a suitable one for the moment. So he simply picked up the Water Shield he had already learned more than
