During this event, Heroes could 'Trick or Treat' by clicking on doors in the various zones. There were timers placed on doors (according to some players) and on player characters themselves (according to others). If I remember correctly, time between one possible door spawn and the next for a given player character was two minutes. For this reason, working in a group made the event much faster. Either a treat was awarded usually in the form of a random inspiration or a trick which would spawn various enemies who came out of the door. The Monster, Eochai could also be found throughout Paragon City in different levels according to the zones. Back then there were no Giant Monsters.
