There wouldn't be confusion. Hits against combatants target hp. Psychic damage won't exist, and all hits are hits -no solid or near misses. Once hp run out CON takes over. CON wounds represent the bad stuff. The kind of wounds that take actual time to heal. 5 minutes of rest don't cut it.
The same type of arbitrary rule that says you cant move diagonally past a hard corner.
Sounds like a neat idea but the design goal was to make HP class based with no stat influence at all.
Indeed. All hit points would be luck, and battle skill determined by class. Things don't get lethal until you run out or are otherwise unable to fight. If HP were not connected to physical damage then swift healing might not be quite so immersion breaking.
Initially it sounds like what you put forward would work fine, something similar to the 'serious wounds' type concept I have read on other parts of the board.
I guess it depends how much you and your players enjoy damage having serious lasting effects on roleplay.
My 2 groups consist of Novices so the simplicity of the rules really helps get the game moving, and hopefully hooking them on dnd with swift paced fun.
I have been looking at introducing a 'serious wound' option when they really have hang of things. Inspired from one of the boards I read someones idea of opting to take a serious wound instead of falling below 0 hp that would have lasting effects somewhat like a disease. Your idea of CON reminds me a bit of that, so now I see the full picture of what you're getting at then, ok, fair enough.
How would this work with being bloodied? Is this when CON kicks in. Or would you be bloodied first at 1\2 HP and then go 'Really Bloodied' when you got down to CON?
How would this work for Monsters? When they start getting down to there CON HP they begin seriously thinking about throwing in the towel? How does this effect whether damage is lethal or non-lethal? Or is that a seperate rule i.e -2 to hit or something similar for non-lethal damge.
Didn't like the idea of removing Psychic damage however.
It also seems to open the door for special attacks which directly hit CON... Poison springs to mind... once you're poisoned or even say burning there's no longer much luck or skill involved when dealing with ongoing damage... you're poisoned and its hurting you... And yet if that were to strike CON directly those powers would be way too strong (a wizard could drop in 2 rounds with 10 CON).
I guess you can rule that despite all logic real damage only kicks in when HP are reduced and CON kicks in no matter what the situation (except sleeping which I remember you mentioned before... making the sleep spell a very efficient way to kill , say, a 400 HP dragon attacking its CON and ignoring its other 370 other HP...)...
However if its some kind of realistic mechanic to a wound/damage system this kind of arbitrary ruling would be somewhat of a paradox.
Anyway, each to their own. From my point of view it seems like you could be opening a bit of a can of worms which may complicate you're game unnecessarily where as there may be other more simple solutions which resolve you're dislike of the 4e lethal/non-lethal damage 'system'...
