The Arena of Slaughter is a small dungeon in Act III of Torchlight II.
It is a fighting arena overseen by a boss monster named Grom the Murderer. He must be defeated to finish the side quest Grom's Arena.
Completing the Arena of Slaughter resets the dungeon, so you may re-run the Arena of Slaughter as many times as you like.
