The stage was completely sealed off by a barrier, with defensive Mages stationed around the stage to block the energy from leaking out after it exceeded the threshold of the barrier.
The students in the World College Tournament were all Advanced Mages, and the damage of a single Advanced Spell was enough to destroy an entire street. As such, even though the stage was the size of four soccer fields, they still could not afford to lower their guards.
Normally, the world organizations did not encourage Mages to duel with one another, mainly because of how hard it was to control the power of their spells. As Mages grew stronger, the destruction they could cause was absolutely terrifying. There were quite a few incidents where Mages were seriously injured in duels.
