Noticing Traps


Rules Questions

To deviate from traps slightly, since it falls in the same just quoted line - A secret door can be both hidden and in your line of sight. That's the point of a secret door, it's disguised so it isn't easily visible. A door that's around the corner or behind a tapestry or something isn't in your line of sight, but also isn't hidden.

A trap can be the same way. The pressure plate may be one of the stones in the floor, clearly visible, but not easily distinguished from the other stones - thus both in line of sight and hidden.

Yeah I don't know how this is being contested.

We're in the rules forum, the rules are clear, you must actively search for traps unless you have a special talent or an active spell that says otherwise. All this other nonsense about high perception scores should go to the home brew section.


Because a wire that is part of a trap should be just as noticeable as a wire that isn't part of a trap.

There is nothing 'magical' about labeling some piece of equipment 'a trap' that makes it invisible to normal perception. Now, of course most traps are deliberately blocked from line of sight so that they aren't detected, but that doesn't mean there aren't traps, like tripwires, that are fully in the line of sight, though perhaps hard to see with a low perception modifier.

Do you know what the words 'not easily distinguishable' mean? You need a high perception modifier to notice the difference.

Seriously, it's rather easy to pump up your perception mods with spells and such to be rocking a +40 or +50 perception modifier. This means you have the ability to notice at 400-500' what most people can notice right in front of their nose. And yet you can't notice the difference between a pressure plate and a normal cobblestone?

Why not?

Please show where in the rules it says that. Otherwise you are the one with the house rule.


Ozy, you're conflating two things. Seeing better over great distances doesn't necessarily mean you're better at spotting things up close. They're consolidated into the same skill, but they don't do the same thing. Say I have a Perception so high I can look 200 feet ahead. That just means I have very sharp eyes, that doesn't necessarily mean I'm very aware of my immediate surroundings, just that your eyesight doesn't drop as sharply. If you can look at that distance with binoculars, you might still miss something that's important, simply because you don't know what you're looking for.

And for what it's worth, I'd say a bear trap openly displayed in a corridor isn't worth a Perception check because it's just as easily perceived as other furniture in the room. Sure, it's hazardous, but I wouldn't award XP for defeating it, because it's easily spotted and avoided. A tripwire is an effective trap simply because it's so small to notice and it's easily concealed/blurs into the background. A tripwire is at least a Fine object. According to the Stealth rules, they get a +16 on Stealth (based on creatures, but you can say the same for objects). Assuming a DEX of 0 and taking 10, a small rope on the ground has a +21 on being spotted. And that's before you factor in actual attempts to hide it. A pressure plate would have about the same modifiers, and so on, and that's only because Pathfinder doesn't go smaller than that.
Simply put, you can't assume an object of a few millimitres in diameter is casually observable in a room that has more features in it.

Except that's exactly what happens. You're just ignoring the rules because you believe a high modifier should change them.

If someone has a +20 to initiative they still don't get to automatically act in the surprise round.

People don't notice things right in front of their faces all the time. If you aren't looking for a trap, you may still notice an odd-looking cobblestone, but your brain doesn't care. It's just a cobblestone.

It's like an 'Eye Spy' book. You are perfectly capable of seeing all of the objects on the page, but you still have to take the time to look to find the needle, the thimble, and the button.


Taking onboard the text in Pathfinder Unchained, which does split noticing from searching, there still doesn't seem to be a big difference in actual gameplay.

One could play the entire game round-by-round but that would be slow and boring. So to speed up the game some assumptions are made. One of these is the movement rate, which outside of combat equates to 1 move action per round. The other assumption is that the character's are passively using the perception skill. Putting those assumptions to speed gameplay back into round-by-round activity we have a round consisting of:
Move Action 1 - Move the standard speed
Move Action 2 - Use the Perception skill

Why can't that 'Use the Perception skill' be used to search for traps without going to the tedium of playing the game round-by-round?

Personally I prefer to have a spot DC and a search DC, because I consider them different actions; but that is a houserule. Maybe adding +10 DC for spotting (+5 for terrible conditions and +5 for distracted) something that could be searched for would fit.

As a side note, I don't consider taking 1/2 a round (3 seconds) to examine a 10 foot square to be a search. It's little more than a glance.

Because if you're taking an action every round for each 10' square you cover, you can't move your normal 30' per round.

Well, you could, but you'd only be checking one of the 3 10' squares for traps, so the others could still blow you up.

Well with a party of 4, they could cover all the squares and we're starting to get into the turn based mechanics breaking the simulation.

Alternatively, with a 20' move rate you could cover 2 10' squares. Except that the next rebuttal will be that you have to move into the square first. That of course raises the question about how you search for the trap before triggering it if you have to move into the square before searching it.

You don't know anyone with a +25 perception, so when you say 'people don't notice things right in front of their faces all the time', I respond with 'people don't cast fireballs either'.

High perception mods, in the +25-+35 range, are basically super-human abilities. Like Sherlock Holmes on cocaine with cybernetic eyes, or something.


The unchained book replaces the normal action types with a new system.

"Search: You use Perception to search a room for salient hidden creatures or clues, or you make a detailed search of a 10-foot-square area to detect traps, triggers, hidden objects, or footprints. When you search an area, this action has the complex subtype."

Now one could argue that perception alone got modified by forcing it to not allow a free action for trap checks.

However there is this:

You keep using that argument, but it has as little evidence as our arguments. Let's reverse it: We don't have proof it works like that, that's right, but you don't have proof it doesn't work like that, either. A hole in the rules can't be solved with a simple "it doesn't say it works like that, so it doesn't," because the inverse is true as well.

You could have a party of 3 or 4 cover all the squares, but you'll need to specify who is searching which square and you won't get your best searcher doing all of it.

Whether you have to move into a 10' square to search it is a different question and a tricky one.

Way to respond only to my first sentence and totally miss the point.


Pathfinder Roleplaying Game Superscriber; Pathfinder Starfinder Roleplaying Game Subscriber

Sadly, I've met GMs who were totally convinced that you could not make a Perception check to search unless you were either moving through the area in question, or else interacting with the object--either of which usually set off the trap if it was of the appropriate kind.

For example, a section of floor that electrocutes you as per shocking grasp? You don't get the check until you move into the area. Congrats you found the trap. You also just got electrocuted.

You don't see the poison needle in the trapped drawer because it was on the inside of the drawer (no line of sight, no line of effect). You need to open the drawer or otherwise manipulate it to reveal the poisoned needle, which generally means you risk getting poked.

I had one GM withold critical campaign information from the players because it was behind a door we had opened. Even though we searched the room, no one said they looked behind the door, or that they closed it again, so we never got a check to "see" the critical clue. By the end of that game, we were all so thoroughly confused and lost that the GM confessed to withholding the information (which he claimed was our own fault).

And when GMing, your ruling is?

As I've said previously my ruling, which may not be RAW but I believe to be consistent and fair is that:
Each character gets a perception check just before the trap goes off / just as they pass the secret door / etc depending on the situation. If a character states they are searching an area then I often have a separate DC to take into account they are actively looking. I also encourage the players to say where they are looking, e.g. in the wardrobe, under the bed etc - I would hate it (and it doesn't happen in my campaign) if a player were to say I walk into the room and take 20 on search, what do I find.

It may well be that in making my ruling I have made some feats or abilities worthless, but the group is having fun and that is the main thing.

In fact it does exactly necessarily mean that because, as you note, they are consolidated into the same skill. If you ask a Pathfinder to roll a skill to see how well they pick out close-up detail, guess what skill they roll? Perception. And guess how well someone with a +25 perception can pick out such detail? You can't, because you have absolutely no reference point.

Ok, now what if the bear trap had a custom paint job to try and blend in? Say a DC 5? Still can't 'perceive' it without an active search? And so on... There has to be some level of 'hidden' where you say an object, trap or not, can't be passively perceived. And in my view, that threshold is whether it is in your line of sight, or it is not.

There is nothing else that makes sense from a self-consistency standpoint.

Wait, so you don't let people make passive perception checks for anything with a DC of 20 or higher?

? I'm using the rules. The rules give a perception DC. If my passive perception beats that DC, I notice it.

That's the rule.

You're the one trying to sidestep that rule by trying to bring in 'real world' arguments about how people can see but not 'notice' things.

If my character has a +100 perception modifier, he notices things, passively, that have a DC30 check. Even if he's distracted (+5), even if it's 50' away (+5) even if it's raining (terrible conditions +5), because that's how you use the rules to check if something is noticed.

If you arbitrarily say he doesn't notice it because he's distracted, you're not following the rules. If you say he doesn't notice it because it's too far away, you're not following the rules. If you say he doesn't notice it because conditions are terrible, it's raining, you're not following the rules.

So, once again, trying to use 'real world' assumptions about how perception works based on a 'normal' perspective is just flat out wrong.

I was not sidestepping the rules. I was giving you a simple, real-world explanation to help you understand why the rules are the way they are. You are ignoring the rules. You need to take an action to search an area.

And I'm not Quentin.

Sorry, sometimes your arguments seem the same.

The point I have been making is that your 'real-world' argument makes as much sense as using a 'real world' argument as to why you can't cast a lightning bolt underwater. Pathfinder doesn't operate under 'real world' constraints, and that goes for super high skill modifiers just as much as magic spells.

Tell me, what can you perceive with a passive perception check? Is there a limit on the DC?


_Oyz_: I agree with you.

wraithstrike: Yep, it seems that from what Mark said, it's not currently a rule. So passive trapfinding is the current RAW but they are thinking of FAQing it.

I don't think much more than that needs said.


Passive trap finding isn't the current raw.

Otherwise racial abilities like stone cunning, rogue talent trap spotting, and the spell find traps are all nonsense.


Trimalchio wrote:

You can't use the fact that some abilities/feats are redundant to define how RAW works. Sometimes abilities are redundant. Also, those abilities give bonuses on top of passive checks.

There is a section for Pathfinder called Traps. In this section it defines a perception DC to notice a trap (not search/find), yes that word is used explicitly. Furthermore, it has this language:

Quote:
Creatures that succeed on a Perception check detect a trap before it is triggered. The DC of this check depends on the trap itself. Success generally indicates that the creature has detected the mechanism that activates the trap, such as a pressure plate, odd gears attached to a door handle, and the like.

Note, no indication that passive perception is not allowed. Also, if you're searching for a trap, of course you want to find it before it is triggered (not much use otherwise). The only reason to explicitly call that out in the rules is to emphasize that players get a passive check to detect a trap before they blunder into it, just like an ambush.

Finally, in skill section, for perception:

Quote:

Common Uses

Notice Someone/Something
...

Perception is also used to notice fine details in the environment. The DC to notice such details varies depending upon distance, the environment, and how noticeable the detail is. The following table gives a number of guidelines.

Then it provides a table listing common DC modifiers for noticing sounds/objects/etc..including traps and secret doors.

Nowhere in that table is any indication that some of those things can only be found be actively searching. The rules simply don't specify this. Furthermore, since searching is apparently restricted to a 10x10' square at a time, distance wouldn't apply, so obviously those sentences and subsequent table refer to passive noticing, not active searching.


Trimalchio wrote:

Not even close to true. Those abilities give a second check, essentially a re-roll. Are you saying re-roll abilities are useless?

That's not what they say they do. It would be a second check if you're not actively looking, and a third check if you are (1 for walking within 10 feet, one for the passive perception and 1 for looking)


So are you actually saying the Core Rogue talent does nothing at all?

Trap Spotter wrote:
Benefit: Whenever a rogue with this talent comes within 10 feet of a trap, she receives an immediate Perception skill check to notice the trap. This check should be made in secret by the GM.

What, if anything, does this Talent do, under your interpretation?

Also, are you make a firm distinction that an active Perception check is always a search and thus limited to a 10' square? You couldn't, for example, take an extra long look from the door of a room to look for enemies hiding in it? Guards on high alert can't make active perception checks to spot approaching stealthy enemies?


1 person marked this as a favorite.

The phase searching for traps is keyed throughout the Pathfinder rule set. Take a look at the deathteap ooze whose ability makes no sense with your interpretation, or look at the sift spell, or the before mentioned rogue talent, or read this post from the creative director . The mountain of evidence and text all point to requiring a search action to find traps.

You're not understanding the historical context that Pathfinder was built out of 3.5 and includes several differences, omissions and distinctions. If memory serves 3.X had a separate search skill check as opposed to Pathfinder's consolidated spot check.

The transition from 3.5 is some of the strongest evidence. Pathfinder consolidated the Search and Spot skills into Perception, but didn't change how they work. Search used to be based on Int!

Again, shouting that I'm wrong doesn't necessarily mean you're right. I was just saying that "far-sight" and attentiveness to details don't fall under the same skill, but do in Pathfinder. Yes, bringing in real life might have been a mistake, but that also means your "you don't know what it is to have a +25 to Perception" also doesn't fly. I'm willing to concede that I may not have been right, but that doesn't automatically mean you are.

I'm going to stop splitting hairs over this. We're not going to convince each other to adopt our own point of view. I find "passive" Perceptions a stupid thing, you don't. Here's my take: if anything's not in direct line of sight, however badly it is covered up, you can't see it "for free," unless it's really obviously concealed. However, if a player says "I'm going to search the room," I'll give them whatever information I think they can easily find without them having to roll a d20.

A tripwire is an effective trap simply because it's so small to notice and it's easily concealed/blurs into the background. A tripwire is at least a Fine object. According to the Stealth rules, they get a +16 on Stealth (based on creatures, but you can say the same for objects). Assuming a DEX of 0 and taking 10, a small rope on the ground has a +21 on being spotted. And that's before you factor in actual attempts to hide it. A pressure plate would have about the same modifiers, and so on, and that's only because Pathfinder doesn't go smaller than that.

Simply put, you can't assume an object of a few millimitres in diameter is casually observable in a room that has more features in it.
Wait, so you don't let people make passive perception checks for anything with a DC of 20 or higher?

No, that was just an example of why things might be more difficult to spot than you'd think.

Seriously, it's rather easy to pump up your perception mods with spells and such to be rocking a +40 or +50 perception modifier. This means you have the ability to notice at 400-500' what most people can notice right in front of their nose. And yet you can't notice the difference between a pressure plate and a normal cobblestone?

Why not?

People don't notice things right in front of their faces all the time. If you aren't looking for a trap, you may still notice an odd-looking cobblestone, but your brain doesn't care. It's just a cobblestone.

It's like an 'Eye Spy' book. You are perfectly capable of seeing all of the objects on the page, but you still have to take the time to look to find the needle, the thimble, and the button.

You don't know anyone with a +25 perception, so when you say 'people don't notice things right in front of their faces all the time', I respond with 'people don't cast fireballs either'.

High perception mods, in the +25-+35 range, are basically super-human abilities. Like Sherlock Holmes on cocaine with cybernetic eyes, or something.

You keep using that argument, but it has as little evidence as our arguments. Let's reverse it: We don't have proof it works like that, that's right, but you don't have proof it doesn't work like that, either. A hole in the rules can't be solved with a simple "it doesn't say it works like that, so it doesn't," because the inverse is true as well.

? I'm using the rules. The rules give a perception DC. If my passive perception beats that DC, I notice it.

That's the rule.

You're the one trying to sidestep that rule by trying to bring in 'real world' arguments about how people can see but not 'notice' things.

If my character has a +100 perception modifier, he notices things, passively, that have a DC30 check. Even if he's distracted (+5), even if it's 50' away (+5) even if it's raining (terrible...

There is no "passive perception" rule, just what you make of it. All we have to go on here are our own interpretations, and they might vary from person to person. I believe we've already demonstrated we won't be able to convince each other of our own point of view, but I'll just clarify myself:

"Passive perception" for me entails what you'd notice without putting in any effort. Room features, scent, all those sort of things. Is something immediately dangerous to you when you're surveying an area. Is there a troll swinging a club at my face? This is all without any dice rolls or modifiers.
"Active perception" involves dice rolls. This is a state of conscious awareness. Here, that "Sherlock-vision" might apply, assessing every single element in a certain space for its possible use.
As you said, I have no idea how an insanely perceptive person works, but as I said, I also don't have proof he doesn't work like that, so here we go anyway: you're not going to tell me that a person with high Perception is at the peak of his awareness at all times, that's why it's called "passive." He might notice more things, but not everything within that two-second moment. He can't solve a "Where's Wally?" puzzle from across a 20-foot room, see three people hiding behind objects, the hidden treasure pile in the corner, and the tripwire right in front of him all in the same two seconds.
Again, this is my interpretation and you have yours. Neither of us is actually supported by the rules, so I'm going to leave it at that and stop this argument.
The only difference might be that someone is always looking out for stuff (and really, why wouldn't he?), which is a reasonable explanation, but mentally exhausting. If your player says "I'm going to watch out for traps all throughout this dungeon," I'll expect they'll go a lot slower, and fatigue creeping in. Hyperawareness is tough to keep up for a long time, but in return I'll let them automatically spot things I think they'll either find important or think they have a good shot at of noticing automatically. There, you have your compromise, you happy?

There is a table that lists DCs to notice everything from a creature standing right in front of you, to a trap, 50' away, in the rain, while distracted.

That table only differentiates between those two cases by the value of the DC, not any 'active' vs 'passive' rule.

If you say I can passively notice that troll swinging that club, then I can also do so if that troll has been shrunk down to fine size, and if that fine troll is using stealth, and if it's raining, and if he's 50' away. Granted, the DC gets higher and higher, but it never switches to not being a passive check.

So, now slap a 'trap' label on that troll and suddenly you can't 'notice' him passively? Nah, that ain't the rule. My interpretation is supported by that table which lays out the DC to NOTICE details in the environment, not find them while searching.

Happy? Not in the least, because you're doing the same goofy thing of trying to apply what you think 'real world' would happen to essentially super human characters.

Mental fatigue from searching, but no problem casting spells all day long, swinging your sword all day long, walking for miles all day long, in armor, through mud. Why? Why insist on imposing so-called 'real world' limits to mental activity only to things like noticing environmental details.

It makes no sense.

Searching for traps was a full-round action in 3.5, so unless you have a rule that grants a reactive check to find traps, characters have to take an action to perceive traps.

The phase searching for traps is keyed throughout the Pathfinder rule set. Take a look at the deathteap ooze whose ability makes no sense with your interpretation, or look at the sift spell, or the before mentioned rogue talent, or read this post from the creative director . The mountain of evidence and text all point to requiring a search action to find traps.

You're not understanding the historical context that Pathfinder was built out of 3.5 and includes several differences, omissions and distinctions. If memory serves 3.X had a separate search skill check as opposed to Pathfinder's consolidated spot check.

If you look through trap abilities, you'll see :find, locate, search, spotting, and locate. So searching isn't the 'go to' term for traps abilities.

Hmm, Pathfinder. Sorry, your 3.5 rules do not apply. If you look under either the Perception skill, or under the Traps section of the Pathfinder rules, you will find no such 'action to notice a trap' rule. Nor is it listed in the standard or move action charts. The rules provide no differentiation between noticing a trap or noticing an ambush.

Explain this:

Quote:
Creatures that succeed on a Perception check detect a trap before it is triggered.

Does that sound like something you need an action to use to 'search' for a trap? Not to me it doesn't.

Yes, since it doesn't say "creatures receive a Perception check to detect the trap before it is triggered". Since there is no rule saying a free check is granted, an action must be used.

Intentionally searching for stimulus is a move action.

If you succeed, you detect the trap before it is triggered. If you fail, you do not.

So, if you're searching for traps, and you fail your DC to detect the trap, you automatically trigger it? Is that what you're claiming?

Quote:
Perception has a number of uses, the most common of which is an opposed check versus an opponent’s Stealth check to notice the opponent and avoid being surprised. If you are successful, you notice the opponent and can react accordingly. If you fail, your opponent can take a variety of actions, including sneaking past you and attacking you.

Where does it say you get a free perception check? It says you make an opposed check, it doesn't say you get a free perception check, so by your argument, you have to take a move action to search for an ambush or otherwise hidden/stealthy creature?

Yup, it may. So where does it say you get them for free, and under what circumstances do you get them for free? Also, noticing a stealthy creature isn't always or only about surprise, so that rule wouldn't apply then even if you thought it provided free checks (which it doesn't explicitly).

Is a trap observable stimulus? I say no. A Stealth-using character is.

And you base that on what rules? Let's check the perception table, both are listed. Neither has any special comment regarding whether it is 'observable stimulus' or not.

Therefore your interpretation is 100% arbitrary.

There are absolutely no rules that say you must use an action to 'search' for a trap, but you can 'notice' a stealthy character for free.

How is a tripwire 'not observable'? How is a pressure plate 'not observable'? How do such things get detected when they are searched for if they can't be observed?

? No, I don't think that's what you're saying. In fact that was what I was saying. And the reason I was saying this is that you seem to think it matters in the least what the 3.5 rules say.

It doesn't.

If the 3.5 rules say something, and Pathfinder is silent, the 3.5 rules mean nothing. If the 3.5 rules say nothing, and the Pathfinder rules say something, the 3.5 rules mean nothing.

There is no combination or scenario where the 3.5 rules have any impact, whatsoever, on the interpretation of the Pathfinder ruleset because 3.5 is not Pathfinder.

So, because 3.5 rules are irrelevant they add absolutely nothing to the discussion of Pathfinder rules. Granted, I could have explained this using more words, but I thought this was inherently understood since we're not talking about 3.5, we're talking about Pathfinder.

But sure, pretend otherwise if it makes you feel better. Doesn't bother me any.

So, if I were to suggest to you that there is no specific RAW supporting the idea that traps are not observable stimulus, any more than stealthy creatures, you would have to concur?

I mean, that's really all I've been saying. Obviously GMs can rule how they like.

You seemed to be arguing otherwise. My apologies.
