Here you'll be able to fight mobs in a controlled environment. There
nis a mobspawner (I built the whole place around a dungeon) that you'll
nbe able to turn on and off thanks to the mod controller block that controls torches. The
nspawner is located above the arena floor on a floating platform which
nenables it to stay in darkness when the torches around it is turned off.

The Arena is located on the server minecraft.bytescape.com, northeast of Bytescape City just outside of Howling Elk in the water.
