It doesn't matter what we do in real life or, say, in a LARP. We're talking about what the rules say.
OK, we're done. I have shown you time and time again what the rules say about stealth and surprise, and the only thing that you are pointing out is that, in your mind, people are always travelling, which is simply absurd. On top of not being able to properly read ONE SENTENCE, see just below.
Except when it isn't "on," which is laid out clearly in the rules.
Except, you are not reading them, once more. The only thing that the rules actually say, and it's only when a group is travelling (you know, on a journey, not going to the bathroom to barf), is that they don't contribute their passive perception to the GROUPs chance of noticing hidden threats. AND THAT IS ALL: "Characters who turn their attention to other tasks as the group travels are not focused on watching for danger. These characters don’t contribute their passive Wisdom (Perception) scores to the group’s chance of noticing hidden threats."
Does it say that they don't get their passive perception for surprise ? NO (It actually refers straight to the surprise rules for this).
Does it say that hidden creatures approaching don't match their stealth check against their passive perception ? NO
The ONLY thing it says is that they don't get to contribute it to the GROUP, meaning that they can't warn others and that people failing their personal checks might indeed be surprised.
You are so scared of perception that you are forcing every one to use things like marching order and task assignment for travelling in all situations, and on top of that, misreading ONE SENTENCE ?
The rules don't make any distinction between when they apply
They apply when travelling. Full stop. By the very definition of them, and the common use of the word "travelling" in plain english.
because all scales of movement are covered in the section under discussion. They apply all the time as the characters explore the world. Do something other than stay alert for danger and your passive Perception doesn't apply unless you're a ranger in favored terrain. Failing to take that into account boosts the power of Perception.
No, it makes it in line with the intent of the designers, as I've shown to you, again, and again, and again. Here it is, as a reminder: ". Firmly in the DMS hands, we even say that the being out in the open part, the DM can ignore if the circumstances are right like you might be sneaking up on somebody who's watching, let's say some instals perform on street of water deep. And they might be so engrossed by the performance that even though it's broad daylight. There's no fog. And you're just walking right up behind the person. The DM might decide, well, you know your dexterity. Spell check was good enough, and this person is so distracted I'm going to let you do this right out in the open. Now the DM might decide though, okay, this guys distracted, so I'm going to let you just. I'm going to let you attempt this, but you might get a lousy roll. Which means maybe you bumped into somebody you tripped, you did something to give your position away, or even if you don't mind aside, maybe you didn't give your position away, but it just means you utterly failed to sneak up on this person. So again, this is a great example of the environment really plays a big role in the attentiveness of other people. It makes sense now going back to passive perception. This is, as its name implies, passive.
And it's considered to be ALWAYS ON, unless you're under the effect of a condition like the unconscious condition that says you're not aware of your surroundings that really the practical effect of that is basically your passive perception is shut off.
Passive perception is on basically whenever you're conscious and aware. Advantage and disadvantage can be applied to it if you have advantage on pass on, let's say perception checks in general. Then it would affect your passive perception by giving you a + 5. Similarly, if you have disadvantage, you have minus five to your passive perception score, because its passive a player does not get to say they use it. This isn't this isn't something people using my passive lesson right now.
You know, it's ALWAYS ON. That's the baseline."
Here you go, the lead designer telling you in absolutely clear words, that it's the baseline, that it's always on. What more do you need ? Sheesh...
He is even telling you when it's not on, it's when you are basically unconscious. Not when you are scribbling in a notebook for a few seconds.
I'm cutting the rest because, honestly, telling me that you are reading the rules and know the designers intent and I'm not is just plainly laughable at this stage.
