Castle of the Robber Knight

If your HP reaches zero, you drop to the ground and risk dying. You cannot move or perform any actions except trying to rally (below).

Death Roll: On your turn in each subsequent round, you must make a death roll – a roll against your CON. The death roll cannot be pushed if that optional rule is used. Record the results of your death rolls on your character sheet. After three successful death rolls you recover D6 HP and stop making death rolls. After three failed death rolls, your player character dies. Rolling a dragon counts as two successful death rolls, and rolling a demon counts as two failures. If the combat ends, keep counting rounds until all death rolls have been made. Any failed death rolls are reset if you survive.

Rally: Another player character within 10 meters and earshot can PERSUADE you to rally and keep fighting despite having zero HP. This counts as an action. If you rally, you can continue acting as normal, but must keep making death rolls as described above. You can even try to rally yourself, rolling against your WIL with a bane (instead of PERSUASION).
