Walkthrough
Like the Mutagen Puzzle, this is a major puzzle that usually requires out-of-game efforts to solve. It is a music-themed cryptography puzzle where you have to break a musical note cipher. You will get both the ciphertext and its decryption keys, so the objective of the puzzle is to read the instructions and implement a decipher.
The solution for this puzzle is different for each playthrough, but the same decipher will work for any given ciphertext and its keys. The puzzle also changes with difficulty.
- Easy: A separate encrypted line which contains the tech vault keycode digits, alongside random titles of lemurian compositions that can be used to test your solution before decrypting the numerical code.
- Normal: The encrypted keycode line is removed. Instead, it is randomly inserted into the lemurian compositions. Keycode digits may appear as text (e.g. six instead of 6).
- Hard: Punctuation, spaces and the like are ditched. Instead, all symbols are in groups of five. Roughly 7% of characters are corrupted, appearing as an asterisk.
- DOMINATING: Same as hard. Corruption frequency might be higher.Verify

Random puzzle text
These are the random titles of Lemurian compositions used in the puzzle, before any added corruption or tech vault keypad digits. If your own deciphering solution is not forming any sensible text, these might help pinpoint the error without relying on solvers written by others.
