Ok so I'm on the third quest for her, the one to let out Taygen's Purity Agent for "temporary mayhem" but I'm having trouble finishing it and the G5 walkthrough is unfinished for the Dera Reaches. I've cleared out the Spire and the control panel is all mine, the options are:
More energy
Drain energy
Emergency dump
Energize agent
Obviously number four is what I want but if I choose that option a dialogue comes up about how the door to the control room gets shut and you die in their from exposure to the Agent. I know there is a stabilization conduit in the north-western end of the Spire and the only option that gives is to turn off the power flowing south to the lab. I've tried everything but I'm not sure how to proceed, can anyone please explain what I have to do to complete Litalia's third and hopefully final quest?
