@11blonks Then it would just mean that the human form is already the closest to the divine form among the mortals, without any evolutionary steps needed. That is, the same thing but merely from the opposite direction.
This is some world-spanning discussion on the human form. Let me add a fun bit. @Kaarme The Bible reference is probably the iffiest of them all, as god is supposedly without form (too base an idea to apply to GOD) and the deeper (or something) interpretation seems to be that god's image is entirely mental, as in Humans are the only creations that are sentient, thinking beings with the ability to choose, blah, blah, blah.
Clearly, none of the people writing this have ever observed house pets, dolphins, apes...
This chapter shows that she literally can't die and immortality literally means she is immortal, not one of those "But you can still die if somebody kill you" kind of immortal.
With that said, what's there at stakes here? Every fight become meaningless because she can just win every fight by redoing it enough times
@musicfreak12 - just because you cannot die, doesn't mean you can always achieve your objectives. Fantasy is full of beings sealed away for centuries because they cannot die.
Also, the qualifier "within the system" matters. It means there are things outside the system that can still kill her.
For example, wine is outside the system, and no amount of poison resistance helps.
