Near-Death Experiences
Rodney and I had talked a while back about hit points, going negative, dying and the like. I've been thinking about it, and having only 10hp between unconsciousness and death might be a little low. It seems that higher level monsters have more of a chance of outright killing someone if they are at low HP at the beginning of a round. Whether this is 'realistic' is less of a concern for me than whether it is fun. I always want there to be a chance for player death because without that there's no true risk, but having a very small margin disallows me as DM from allowing other things to happen to the players.
For example, BBEGs (Big Bad Evil Guy or somesuch) in many books, movies and other fantasy literature love capturing people for their schemes or just to attempt to gather information. Being captured could also provide a different type of roleplaying, as well as allowing for some interesting escape attempts. It also gives any surviving party members a conundrum as they attempt to figure out whether to finish a quest or attempt a rescue. However, at least to me, it seems these things are unlikely to happen when one slight wrong move on an NPC's part can kill someone.
One other aspect of this for me is that in the new campaign, blood debt, ransom, honor and servitude will be part of the warrior culture (Similar I think to some of Feist's work), where capturing an enemy provides a valuable resource where killing someone is only something one does to the dishonorable or on a battlefield.
So anyway, my basic thought is to come up with a formula to extend 'death's door'. My initial thought is to allow players to go negative = 2*constitution+level. Fighter classes would also get a bonus of 5 or 10 additional hp. Players would still go unconscious at 0, they would just not die quite so quickly. For example, this would allow a 10th level rogue to not die until -40, assuming a 15 Con.
Now, all this assumes people think this rule needs modifying. If folks don't mind the rules as written, I am ok with keeping them, but I wanted to offer an alternative. Please let me know what you think!
