I just recently started using choir of one and realized that I don't have any of the intrinsic upgrades or catalysts unlocked for the weapon, so I looked up a guide on how to get them and the room where you activate the portals doesn't have the vex obelisk thing in it to start getting them. I checked nessus to see if I am just missing the true instance of the exotic mission there, (as i was using the portal to load the mission) but it doesn't appear to be anywhere on nessus, unless I am blind. If anyone has any insight on how I could get the intrinsics and catalysts lmk.
