Death City Battle Event

The Death City Battle Event is an event that happens near the end of the 10th questline. It happens on the second floor of the Death City Castle. It is completed once the player has killed 50 enemies. The easiest way to complete this event is to aggro a whole group of enemies onto you and bring them infront of the defense systems, and fire away. Make sure you count how many enemies the defense systems kill. This event can usually be completed as fast as 5 minutes or as slow as 15 minutes (if you aren't taking breaks from it). Bring a diamond sword and maybe an extra set of diamond armor, as this will be a long battle.
