I am greatly saddened to say...

[Maragaram]

That it is impossible to have a character start with 0 HP, even if said character is a sorcerer with 3 CON. Even worse, said character will continue to gain at minimum 1 HP per level.

The dream is dead. Unlike my character.

You can aways try to walk arround with your pulses slit open bleeding with 1 HP, dieing and stabilizing at the minimum movement.
OR, just focus a LOT on bluff and make bluff to yourself that his HP is only a visual bug.

I ask this politely: Why would you want a char with 0 hp? I feel like I missed something .

[IndifferentPerson]

if char has 0 hp hes dead, if hes already dead he cant die, char is immortal.

IMMORTALITY ACHIEVED. or almost.

[Faye]

Lichdom at Level One!

...Almost. Not really. At all.

[Rystefn]

if char has 0 hp hes dead.

False. A PC doesn't die until -10.

[IndifferentPerson]

if char has 0 hp hes dead.
