Magic barriers usually restrict the caster's movements. So, the caster has to remain in a single position to concentrate on the barrier's attributes like who to allow entry or exit, and who to allow using magic.
That's why I thought finding the caster would be easy.
But according to the man in front of me, he is the caster of this giant barrier, which might have been a bluff. Because, he is moving like crazy, while fighting Drake and others.
Well, we would find out soon enough.
However, the barrier I have casted is a little different, because it is a skill given to me by the system. That implies to the fact that I am the one who is giving commands and the system is executing it.
Which means, I can move inside it without concentrating on each and every attribute.
"Heh~? That's a pretty skill you have there."
He is still trying to be playful, while a bit uneasiness is visible on his face.
