The Mad Monk

"Want to break into my prison!! Come get it over my body!!" shouted the Warden

The Warden fires a few fireballs towards the groups to disturb the person that is casting the magic circle in the sky [2nd Circle - Fireballs]. 

Seeing the incoming attack from the warden, "Hmph.. mere fireballs are nothing for me." said one of the people in the group.

Then, the black-cloaked man waves his hand and creates a bluish barrier in front of the group [3rd Circle - Bubble Barrier]. The moment the fireballs reach the bluish barrier, they get dissolved without creating an explosion like it is supposed to do.

As the fireballs turn into some water vapor, a few of the surviving guards launch an attack towards the group from afar. However, all of them couldn't penetrate the [Bubble Barrier] as most of the guards used fire magic.
