As you continue through Elden Ring you will come across the Grand Lift of Dectus, this is the place that connects both Liurnia and Altus Plateau.
However in order to activate the Grand Lift of Dectus we are going to need to find the Dectus Medallion. There are two Dectus Medallions a right and a left. Only with both pieces can we activate this lift.
DECTUS MEDALLION (LEFT)
In order to find the Dectus Medallion (Left) you will need to head to Fort Haight. From there continue on up the stairs.
Head into the room on the right and up the ladder. Here you will find a chest containing the Dectus Medallion (Left)
DECTUS MEDALLION (RIGHT)
The Dectus Medallion (Right) can be found and located at Fort Faroth. When you arrive head inside the fort and climb up the rather long ladder.
Once at the top of the ladder you will come across a chest with the Dectus Medallion (Right) inside.
GRAND LIFT OF DECTUS
Now that we have both of the Dectus Medallions it is time to head to the Grand Lift of Dectus. Step on the lift for a scene.
