Occult and their non-possible deaths

[Unknown]

Few years back, I wanted to make a graveyard with only occults in it, and with every ghosts types they can be. However, certain occult may not become certain types of ghosts so I ask if you could give me some insight if certain are immune to certains deaths or something like it.
For exemple:
The mummy does not leaves a fire ghost(or at least when I tried): They burn instantly without leaving any urn/tombstone.
The simbot and vampire cannot be curse: They always win against the mummy.

Thanks for the help. I'll share the graveyars when I'm finished

Sims who aren't witches are immune to the Haunting Curse that comes with Supernatural, as only witches can cast the curse.

Obviously, non-vampires can't die of vampiric thirst.

Any more advises?
