Disabled: A character with 0 hit points, or one who has negative hit points but has become stable and conscious, is disabled. A disabled character may take a single move action or standard action each round (but not both, nor can she take full-round actions). She moves at half speed. Taking move actions doesn’t risk further injury, but performing any standard action (or any other action the DM deems strenuous, including some free actions such as casting a quickened spell) deals 1 point of damage after the completion of the act. Unless the action increased the disabled character’s hit points, she is now in negative hit points and dying.
A disabled character with negative hit points recovers hit points naturally if she is being helped. Otherwise, each day she has a 10% chance to start recovering hit points naturally (starting with that day); otherwise, she loses 1 hit point. Once an unaided character starts recovering hit points naturally, she is no longer in danger of losing hit points (even if her current hit points are negative).
Dying: A dying character is unconscious and near death. She has –1 to –9 current hit points. A dying character can take no actions and is unconscious. At the end of each round (starting with the round in which the character dropped below 0 hit points), the character rolls d% to see whether she becomes stable. She has a 10% chance to become stable. If she does not, she loses 1 hit point. If a dying character reaches –10 hit points, she is dead.
