This arena is surrounded by self-sealing emergency glass. When a competitor is thrown against the glass, the temporary breach blasts out hot steam and caustic gasses before closing. Within the arena there are target drones that circle above the competitors, attempting to get a positive lock. If a competitor is targetted for 5 seconds, they are blasted by a stream of damaging plasma. The arena's plasma supply is constantly regenerating, so the more time passes the deadlier this hazard becomes.
