LE Proper Immortality

[Strokend]

I want a mod that sets the character to be immortal upon starting up the game (as in, upon loading or whatever, since it seems to forget you're immortal when you close the game), and then restores a modifiable amount of health upon reaching zero health. The script, of course, should watch for decapitation, or whatever other methods of dismemberment, so that it can turn off immortality and let the player truly die in such a case.

 

This kind of mod would be helpful with any mods that effect the player when their health is low without risking their death.
