To find Decorum Cipher in Remnant 2, complete the Terminus Station dungeon in N’Erud and get to the last train wagon. During this challenge, you must fight against hordes of small Robot Grunt enemies. You can use any AOE builds, but the Engineer class and its deadly turrets will come in handy in this fight. In addition, you have to defeat the Restless Spirit boss.
Once you overcome the difficulties, here’s how to get to Decorum Cipher:
- After defeating the boss, go down to the station and go along the narrow corridor under the large cables.
- Go straight ahead, then squeeze through an even narrower passage under the cables.
- Climb the stairs to the brightly lit room and go through the vast passage on the left side.
- Go down the open hatch on the train roof and collect the Decorum Cipher. In addition, the powerful weapon Atom Smasher.
If, instead of the Terminus Station dungeon, the procedural world generation sends you to the Dormant N’erudian Facility, you can find a Memory Core II and get a Core Booster subsequently. At the same time, Decorum Cipher and Pulse Rifle will remain unavailable until you try a new playthrough or adventure mode.
Once you get the Decorum Cipher, you can use it in the Ascension Spire location to get the Pulse Rifle:
- Head to the room with The Custodian.
- Jump into the hole behind the statue on the left side of the room.
- After going down, go to a small room with a console next door.
- Place the Decorum Cipher into the console, and a secret room will open nearby.
- Go there and get your new Pulse Rifle weapon.
