The walls I created were just for show, while the real show stopper is the barrier. This barrier not only reflects spells used against it back at its attacker, but it also makes the attacks homing attacks. These attacks only reflect back at those within the barrier. On the outside, they just get spun away. But there is another thing that this barrier does. If someone tries to touch it, they will not only be shredded to pieces, but they will feel the pain tenfold as they do.
