I've read about a non-consumable anti-borg device used in a Defera Invasion zone mission (that requires using it on 100 borg). I can't seem to find this mission anywhere. Do I need to do something to unlock it? I've spoken to all the Deferi mission-givers in the base camp, including the Deferi who gives the temple quests, and none of them have it.
It is a zone-wide mission that Julia (the temple girl) hands out randomly. Usually there's only one zone-wide mission from one of the three contacts (city, power plant and temple) available at any given time. If I'm about to leave Defera, I'll usually run through all the contacts to see if one of the zone-wide missions has popped and claim it so I can run it the next time I log in.
