A question was raised in my campaign once - do unconscious characters fall prone? There's obviously a degree of common sense here, but it remains unclear by RAW just what effects unconsciousness has. Looking over the mythic rules and finding an ability referencing this (Shout of Defiance) brought it back to mind.
I'm curious now if there has been any clarification over what exactly unconsciousness involves, and how people handle it. For example, falling prone makes plenty of sense, but do characters also drop their items? This would make sense realistically, but having to take two move actions and provoke AoOs twice just to get back in the game seems a rather harsh penalty for when the PCs are already having difficulty surviving.
So yes, as much as logic can dictate a fair amount, I'd like to know more on how the rules interact with it.
It's never been strictly covered.
It is reasonable to assume that people rendered unconscious will fall prone and drop any held items.
Meaning a move action to stand up and another to pick up an item. Assuming they are raised from consciousness during combat.
Of course, as a GM I've often ignored this because a PC going down in the fight is enough, I don't need to kick him (by hitting him twice and wasting his whole turn) to get back in the fight.
But, I believe that is how it should work.
Unconscious: Unconscious creatures are knocked out and helpless...
Helpless: A helpless character is paralyzed, held, bound, sleeping, unconscious, or otherwise completely at an opponent's mercy. A helpless target is treated as having a Dexterity of 0 (–5 modifier). Melee attacks against a helpless target get a +4 bonus (equivalent to attacking a prone target). Ranged attacks get no special bonus against helpless targets...
...A character with a Dexterity score of 0 is incapable of moving and is effectively immobile (but not unconscious).
If you need anything else than that I think you'll just have to cope with common sense and logic.
