Ok so I beat most of the game without picking up the skull. I feel like I probably missed out on a lot good dialogue.

For some reason I decided to record my playthrough (which I never do) so if you're interested here it is: https://www.dropbox.com/scl/fi/mq1m4fk8golxtgfuxzghw/Amethyst_Cut_2.mp4?rlkey=lk...
There's a cut in the middle because I almost give up at one point and stopped recording. I think it's only missing one short death.
I'll delete this in a couple weeks so if you want to keep it by any chance make sure to download it.
