Try It Now!
If you want to try out a version of this system in your current game,
try the following house rule. It’s not quite the 4th Edition system,
but it should give you an idea of how it’ll feel.
1) At 0 hp or less, you fall unconscious and are dying.
Any damage dealt to a dying character is applied normally, and
might kill him if it reduces his hit points far enough (see #2).
2) Characters die when their negative hit point total reaches
-10 or one-quarter of their full normal hit points, whichever is
a larger value. This is less than a 4th Edition character would
have, but each monster attack is dealing a smaller fraction of
the character’s total hit points, so it should be reasonable. If
it feels too small, increase it to one-third full normal hit points
and try again.
3) If you’re dying at the end of your turn, roll 1d20.
Lower than 10: You get worse. If you get this result three
times before you are healed or stabilized (as per the Heal
skill), you die.
10-19: No change.
20: You get better! You wake up with hit points equal to
one-quarter your full normal hit
points.
4) If a character with negative hit points receives healing,
he returns to 0 hp before any healing is applied. In other
words, he’ll wake up again with hit points equal to the
healing provided by the effect—a cure light wounds spell
for 7 hp will bring any dying character back to 7 hp, no
matter what his negative hit point total had reached.)
5) A dying character who’s been stabilized (via the Heal
skill) doesn’t roll a d20 at the end of his turn unless he
takes more damage.
