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.
On the next turn after a character is reduced to between –1 and –9 hit points and on all subsequent turns, roll 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. (A character who’s unconscious or dying can’t use any special action that changes the initiative count on which his action occurs.)
If the character’s hit points drop to –10 or lower, he’s dead. You can keep a dying character from losing any more hit points and make him stable with a DC 15 Heal check.
If any sort of healing cures the dying character of even 1 point of damage, he stops losing hit points and becomes stable. Healing that raises the dying character’s hit points to 0 makes him conscious and disabled. Healing that raises his hit points to 1 or more makes him fully functional again, just as if he’d never been reduced to 0 or lower. A spellcaster retains the spellcasting capability she had before dropping below 0 hit points.
A stable character who has been tended by a healer or who has been magically healed eventually regains consciousness and recovers hit points naturally. If the character has no one to tend him, however, his life is still in danger, and he may yet slip away.
Recovering with Help: One hour after a tended, dying character becomes stable, roll d%. He has a 10% chance of becoming conscious, at which point he is disabled (as if he had 0 hit points). If he remains unconscious, he has the same chance to revive and become disabled every hour. Even if unconscious, he recovers hit points naturally. He is back to normal when his hit points rise to 1 or higher.
Recovering without Help: A severely wounded character left alone usually dies. He has a small chance, however, of recovering on his own. Even if he seems as though he’s pulling through, he can still finally succumb to his wounds hours or days after originally taking damage.
A character who becomes stable on his own (by making the 10% roll while dying) and who has no one to tend to him still loses hit points, just at a slower rate. He has a 10% chance each hour of becoming conscious. Each time he misses his hourly roll to become conscious, he loses 1 hit point. He also does not recover hit points through natural healing.
Even once he becomes conscious and is disabled, an unaided character still does not recover hit points naturally. Instead, eachday he has a 10% chance to start recovering hit points naturally (starting with that day); otherwise, he loses 1 hit point.
Once an unaided character starts recovering hit points naturally, he is no longer in danger of naturally losing hit points (even if his current hit point total is negative).
