Aight, Ill take a crack at a battle field.

Arena: Hades pits

Description: The fight is held above a large pit of black flames on top of twenty five stone pillars that are in the shape of a square, five pillars by five pillars. Each pillar has a diamater of ten feet, and the pillars are placed thirty feet apart. Also, there are countless chains dangling from the roof, and approximately twenty percent of the chains will fall if some one tries to swing from one chain to the next. The Chains that will fall will change each time the arena is used. In addition, the pillars are perfectly smooth on the side, making it impossible to climb naturallym however magic may still be used to climb it. Since the black flames are not normal fire, it penatrates all fire resistence abilities, magical or not. So even if a Flame elemental fell into the fires, it would still suffer a painful and certain death.

Size: 170 X 170 Feet. Small i believe.
