"Metagalactical" modifies "cryptograph"!
"Discarnate": I don't have the pronunciation facts available, but I imagined the stress to be either on the first syllable or on both of the first two syllables; let me know if you discover otherwise. I prefer "discarnate" to "bodiless."
I honestly don't think of these as difficult, but kind of fun. They're word games.
If you're interested in comments on your epic DDs, just say the word and I'll take a closer look, though I don't know that I'll have anything profound to tell you.
