"A new variable in the equation?! I'll have to to recalibrate this..."...(Battle Hall Signups OP)....
Arena: Stadium Arena
The Stadium Arena is similar to the Tournament Arena, with all weather and seismic activity permitted. There is a lake in the middle so water moves are allowable. It is a circle of hard packed earth around 40 feet in diameter, and digging is permitted. The crowd can become involved in the battle at the referee's discretion. Nature Power's effect is randomised.
