The Tech Specialist? is a captive Rikti scientist of Captive Technician? faction in need of rescue. Two of them (along with a third non-escort version) can be found on the Recover exotic technology specialists mission from Kelly Uqua. Once freed from their captors, they must be escorted to the entrance of the mission. Three waves of Arachnos will attack you on the way to the entrance. As Captives, they are unaffected by enemy damage.
