Death's Door

When a character takes enough lethal damage to drop below 0 HP, he is said to be at Death's Door. Unless other effects counter it, he is Dying, meaning that he is losing one hit point her round. Every round, the character gets a 10% chance of becoming Stabilized. When stable, the character is no longer losing hit points, and will begin to regain them at the normal rate. Another character can make a Heal check at DC 15 as a standard action to stabilize the dying character.

If a character ever reaches -10 HP or fewer, he is dead.
