Perimeter Tower Hylek Waves Defeated x/5

This event occurs after the Defend the Ordnance Corps airship event. Hylek will attack the towers that were built at the start of the Outpost: The Ordnance Corps event chain. The event will fail if the tower loses all of its health. The tower does not have much health so it is advised to complete this event with a group.
