If you die you must make a new character or Go through Revival there are also steps in how you die.
Disabled (0 Hit Points)
Dying (-1 to -9 Hit Points)
Dead (-10 Hit Points or Lower)
Stable Characters and Recovery: you can make yourself stable by rolling a d% to see whether the dying character becomes stable. He has a 10% chance of becoming stable. If he doesn’t, he loses 1 hit point. You can keep a dying character from losing any more hit points and make him stable with a DC 15 Heal check by rolling a d20 die. If any sort of healing cures the dying character of even 1 point of damage, he stops losing hit points and becomes stable
