Reactor Room

The Reactor Room is a sub-area of the Spire of the Watcher dungeon where Persys is lured and damaged. Fireteams need to get Persys inside before the reactor core purge sequence deactivates, ideally before the second yellow wire path is completed. Once Persys is inside, the red nodes reopen so the gate can be shut and the boss sealed in. During the purge Persys absorbs the dispersed radiation, which drops its shield for roughly ten seconds, and the team can damage it in that window.
