The rules state that you either die or fall unconscious when you have 0 hit points. The definition of “unconscious” in Appendix A specifies that you are incapacitated AND can’t move or speak AND are unaware of your surroundings.
EDIT: Maybe I shouldn’t assume you’re talking about 5e. I have no idea about 5.5e or any other edition
OH MY GOD I REMEMBER THIS ONE.
I remember going back and following literally every single possible story path and never making it to the planet Ultima. And then going through page-by-page until I actually found it.
That’s wild, this must have been about 20 years ago. Thanks for reminding me of a childhood memory.
Literally every adventure where we have to enter a potentially dangerous castle/mansion/tower. We’re going to climb or fly up to a higher level window because obviously if there’s a trap or ambush, it’ll be at the front door.
