Return to the Gnomeland Security Headquarters in the Steamfont using the Unstable Tinkered Portal at ( 1780, 453, 837 ) /waypoint 1780.14, 452.72, 837.15. Then head over to Clockwork CXXV ( -536, 174, 954 ) /waypoint -536, 174, 954 where you will see "a stealthy clockwork". It will despawn quickly and drop a wrench on the ground ( -537, 174, 953 ) /waypoint -536.91, 174.08, 953.32. Pick up the wrench.
and examine the admin key to use it. You will be teleported into an instanced zone, Admin Level Access.
This zone has even-scaled ^^ mobs, called "Geargobbler System," so be careful!
While in this zone, you will have a buff on you called "Superuser Access" that increases most of your stats. Caution is still advised, but you will be more survivable against these tough mobs than usual.
The Clockworks can NOT see through Stealth or Invisibility.
Make your way east across the room (you may have to wait for mobs to path away) to the ramps to the upper level. On the central plank (northern side) of the upper level is the Geargobbler System (an NPC) ( 6, 15, -5 ) /waypoint 5.87, 14.98, -5.39. Take the dialog path about his objective to update the quest.
Return to Nell with the information you've collected. The exit from the zone is at ( 49, 1, -23 ) /waypoint 48.70, 0.62, -23.35.
Note : If you don't have stealth it is possible to complete dialogue while under attack, dialogue is not interrupted. If you chose dialogue from top to bottom quickly and then jump from platform when completed it is survivable.
