Dark souls saves very often. you can’t really save scum. if you die, you die. if you fall from a cliff and you quit out before the “you died” shows, you are on the last stable ground and alive. if you quit out during a boss battle you will load in before the boss fog but if you used estus or items they will not be restored. enemies will reset their position if you load in but stay dead if you already killed them. this is true for every platform and every soulslike game made by from soft . if your game crashes you will load in a few seconds before the crash.

but you also cannot really pause the game. your only reliable glitchless way of “pausing” is quitting out
