Do monsters die at 0 HP or -10 hp?

[Sejs]

As has been said already, if it has a con score it dies at -10, if it lacks con it dies at 0.


Generally what I do is for mooks, I'll roll stabilization only once after they hit negative hp. If they make it they stabilize, if not they bleed to death in the appropriate time. For more important NPCs/Bad guys, I'll roll stabilization once per round as standard, just like PCs do.

Note that you do NOT pass out at 0 hit points, you become disabled. You are still conscious and can take actions, though pretty much anything other than moving makes you lose 1 hit point right after the action resolves.

Thanks to everyone for the replies.

And Ottergame, thanks for pointing out my error regarding the PC's condition at zero HP. I re-read the combat chapter in my PHB just to refresh...and you are certainly correct.
