COC : DCOTE Part 11 Air Filled Tunnels
Finally the end of the game. I still don't know exactly what got me past the last part but hey I'll take it. Thank you @GamingHarryYT for the explanation and thanks copilot for a bit more about Ramona and the elder sign.
Gaming Harry's explanation video is here if you want to watch it.

I put this in the comments as well but I found the patch after I finished. It appears to work with the steam and GOG versions of the game and can be found here - https://github.com/sucklead/DCoTEPatch/releases
