The Eighth Circle Shadow Wizard named Hickman Arlington was one of the five Chief City Guard Wizards of the City of Exiles' Vigilance Team.
The spell he was using now was called "Gisley's Shadow Escape Technique," or simply "Shadow Escape Technique."
The learning requirement for this technique was to reach the Six Ring standard and be able to absorb shadow energy.
A Six Ring Shadow Wizard could use this technique to split themselves into six shadows, a Seven-Ring would split into seven, an Eighth Circle into eight, and so on.
As long as any one shadow escaped the enemy's attack range, the rest could teleport to that shadow's vicinity, then merge into one and become the wizard himself, thereby escaping from the battlefield.
Catching such an opponent should be quite difficult, right?
Difficult it might be, but not as much as one would imagine.
Firstly, a shadow's teleportation to another shadow required "charging," which means the wizard had to cast.
