Ultima IX - Tidbits #17: Salvaging the Codex of Ultimate Wisdom after Buc's Den
The Codex vanishes from Samhayne's house when one is thrown into Deceit, but if you use the "wield objects" glitch and have it on you when it happens, it appears above you when Raven returns your things.
I advise saving before speaking with her, because although it didn't crash for me even once, this still seems dangerous. From what I know so far, this closed object might be the same thing like the inventory version, so I'm not sure how will my game act when I get to the end of the Abyss. What happens when I leave the Codex here and what happens if I "wield" it at the scene? If it's anything interesting, I will make a video of it.
As for the staffs I wield, they are from the nearby magic shop: I salvaged them from the inner showcase with flying cheat. If they are there or on the ground when you activate the magic elevator, they vanish, but not when you wield them via glitch. They also stay intact when you remove them as long as the elevator is already there.
EDIT:
Tidbits #51 shows if it's the same object as the readable Codex.
