Ascension Spire

Ascension Spire is the home of The Custodian on N'Erud and is found in Phantom Wasteland and Abyssal Rift. It is a key location for both stories as you can gather information about and perhaps receive aid to help you in your quest. There are also valuable items to be found below the surface.

Just outside the tower entrance is the Ascension Spire World Stone. Inside is a large room where you'll find a humanoid standing in front of a relief depicting several, strange creatures. This is the Custodian:

If you speak with him, he introduces himself and gives you your task in a Seeker's Rest story or gives you interesting information in a Forgotten Prison story. Note that you don't have to speak to the Custodian to complete either quest, but if you're into the storyline, it's definitely worth speaking to him.

When you're done speaking with the Custodian, turn around and head back outside. As you approach the entrance, look to your right to see a short, concealed path that ends at an opening in the floor:

Drop down through the hole in the floor to find the Drzyr Replicator:

There is a Drzyr audio log near the base of the Drzyr Replicator. Listen to it if you like, then notice the two elevators on either side.

The elevator to the right of the Drzyr Replicator leads down into a vault. Directly ahead of you is a shield generator that hums with purple energy. Before you go there, drop off the ledge to the right of the walkway and follow the path to a pedestal where you'll find the Escalation Circuit:

Backtrack to the walkway and approach the energized pedestal. Notice that there are one or two pins inserted into the device and an energy shield blocking the passage beyond:

If you have the Decorum Cipher and/or Memory Core II, insert them into the unused receptacles to drop the shields in the passage beyond. Behind the first shield you'll find the Core Booster amulet. Behind the second shield is the Pulse Rifle long gun.

If you only have the Decorum Cipher or Memory Core II but not both, it's OK. You'll just drop one shield and get the Core Booster. Come back later (maybe in another roll) with the both keys to drop the second shield and collect the Pulse Rifle.

Head back to the elevator and ride it back up. The elevator to the left of the Drzyr Replicator is your exit and takes you up to a plateau outside next to the entrance to the Ascension Spire.
