格姆的实验室

{{spoilers| thumb|Level 1 : Windy Station & Stormy Station thumb|Level 2 : Chilly Station & Goemm's Lab To reach Goemm and his lab, you will use a series of asura portals to transfer between "stations," each gate requiring you to become tuned first by interacting with an Attuner Device. The effect lasts 20 minutes and persists if you fall; it only expires if you log out or die. Without the proper attunement, the portal will transport you to the previous station rather than next one. The second and third Attuner Devices are each guarded by a veteran, so you might find it faster to run past the foe rather than slug it out. Once you reach the lab, you will trigger an event to defeat Goemm. If you fall along the way, any Golem Assistant can teleport you to any of the stations you have previously reached, so at worst, you only have to retrace your steps in the current station.

If you die during the puzzle, instead of just falling, you will have to be resurrected by an ally. If you are in combat when you fall, you might suffer falling damage instead of being teleported back to the first station. The puzzle had previously included an Aetherblade Cache, introduced with the original Sky Pirates of Tyria update. It was subsequently removed but has now been reintroduced as part of the Sky Pirates update, along with an associated achievement. At some point, the Cave Bat guarding the first attunement device was downgraded from a veteran to a normal rank.
