GW2 Collapsed Observatory jumping puzzle guide with detailed explanations and video walkthrough. Collapsed Observatory is a jumping puzzle in the SE portion of Kessex Hills. This puzzle is fairly short and simple but might be confusing for first timers. Hopefully this guide will make it easy.
You will want to head to Cereboth Waypoint on the SE corner of the zone. Once you are there, head south, towards the waterfall.Soon enough, you will see a bunch of oozes that you can just run past and skip.
Once you get past the oozes, jump on the wooden plank below and go through some broken stairs.
At the end of the stairs, you will see this large beam. Ideally, you will want to make it onto the beam as it is the fastest path to the chest. I find the jump fairly difficult personally and I always fall below anyways so I just jump down to the left.
Once you are down there, just run up the stairs on your left and jump on the rocks covered by the waterfall (make take a couple tries).
From here, you can just jump on the beam on top of the tower.
Run down the beam, make these jumps
At the end of these jumps, you will see this little building with an ooze inside it. Kill it so that it doesn’t bother you when you need to jump over the building.Around the building is the wooden plank that will take you to another plank across.
Go up the stairs behind the wooden plank and make this long jump to the staircase here.
Go up the stairs, jump down this hole to fight a baddie and get your chest & achievement!
