A dungeon is a collection of rooms that follow on from each other. You must defeat all of the monsters in a room before you can unlock the next. Most dungeons end with an epic battle against a boss, with rare items as a reward!
Arcade dungeons only have one room. The goal is simple – survive the longest, and kill all the monsters as quickly as possible. The best players will have a statue of their characters erected before the entrance to the dungeon, showing everyone exactly who the biggest heroes are!
