The Forum of Hercules is a fairly small arena with a few hazards in it. The walls are lined with spikes, so you can knock other players into them to immobilize them for a few seconds. In addition, Hercules, who is standing on the top far side, will sometimes come down and smash the ground with his cestus, sending a shockwave that knocks players back, as well as breaking the railings in the back, allowing players to be knocked off.
One last hazard has to do with the entranceway, which is normally blocked. However, it will be open at times and if you go in the hallway and light the brazier, then arrows will rain down on the battleground, doing a good amount of damage to anyone out there.
