can someone please tell me if I even need to need my human status (0 death) for anything special? I have been constantly trying to keep my character at 0 death the entire progression but now that there are some events that require me to die idk what to do
please help
AFAIK it makes no difference.
The main character is already undead from the start, anyway. Hell, he's already undead in Black Souls 1. But some of the older walthroughs mix things up and refer to the Hollowing status that you get after death as 'undead'.
That aside, IIRC the only event that actually
requires you to die is making a pledge/covenant with Victoria. You can't pledge her unless you beat her in her sex game first - and she will tear out your heart and kill you if you do.
Everything else that can be done through dying can also be done through other means (like getting to the Library at the start of a new game - you can use Black Ash, or you can even go all the way to Queensland and go to the Library there via the Chaos Dungeon). Only pledging Victoria doesn't offer any alternatives (which is a shame because her covenant is pretty useful).
