A Perception check is not a Search. Why is there so much problem with this?

Normally a Perception check is in reaction to something, but as an active check it is a Move action.

When a player says "I've doing a Perception check from the door of the room" he is saying that his PC is looking (smelling, listening, feeling, even tasting) from the doorway - more than likely from just outside, to see what he can perceive about the room. This takes a few seconds (a move action). If the player than says "I take 20 and get XX" - this means the PC took one minute (20 move actions) to scan the room.

HE IS NOT SEARCHING THE ROOM.

Yet many judges respond with things like "You know how long that will take? Hours! This room is full of books, drawers, crates, ... it would take you hours to go through all that!" and in disgust at the player for trying to "game the system" he will move the game closer to Players Vs. Judge because of what he perceives the player to be doing. When in reality, often all the player is wanting to do is take a minute to understand his environment a little more.

The player has been taught (or read in the rules) that the way someone checks for something in the game, the way he gathers insight into environment is to say "I take a Perception skill check" and that you can Take 20... so he is trying to do that.

This saves him all the other, direct questions...

"Are there Trip Wires I can see?"
"Is there heavy breathing from behind the box in front of me?"
"Does it smell like dead things in here?"
"Does the air feel unnaturally cold and damp?"
"Does the taste of wood smoke fill the air?

That's all. Really.

It doesn't take all that long, it doesn't break the game, and even saves real time (everyone is not rolling dice, counting up numbers and shouting at the judge at once...). The guy with the best Perception scans the room for danger - and maybe takes a minute - and the judge tells them what he sees/hears/smells/feels/taste...


Also, aside from traps, you don't need to announce that you're looking for anything. Eyes are always open, ears always work.

I believe it usually takes 2 minutes, not 1.

Often if something is "in Stealth" a judge will not give you a perception check to perceive it. Or if something has a DC listed in the scenario, many judges will not mention it if you don't say "I'm doing a Perception Check".

How long does a Perception check take?

Normally it is a move action.
2 move actions a turn, 20 in a minute....
and Take 20 takes 20 times as long as doing the action once, right?

but heck, 2 minutes is better than an hour....
then we get people (both players and judges) who do the 2 minutes per 5' square, and another turn to move from square to square...

I agree with trying to get the players more involved beyond rolling dice, but not all of your conclusions about the skill.
Here's an article from Paper and Pencil dot com from 2012 that discusses (at length) the Perception skill in PF.

OVERVIEW OF PATHFINDER’S SKILLS: PERCEPTION

I doubt there is any skill quite so divisive as perception. I hardly feel qualified to assess it. So many dozens or hundreds of men and women much more experienced than I have spent so many forum threads and blog posts debating back and forth over the issue of perception that I feel presumptuous even attempting to resolve it. But that’s what I signed up for when I said I was going to begin this series of posts, and I’m not going to back out now, so here we go.

If you recall from earlier in this series, I believe disguise and escape artist are two skills which should be house ruled out of the game because they are needed so incredibly infrequently as to be useless. Well, if those skills commit the sin of a deficient frequency, then perception commits the sin of excessive frequency. The skill is so frequently called for, and so necessary, that -C uses the term “Skill Tax” to describe it. Putting points into perception is more of a requirement, than an option. And if something is a requirement for effective play, why clutter up the skills list by giving players the illusion of a choice?

But I’m getting ahead of myself. If you’d like to have perception torn to pieces in front of your very eyes, read -C’s two posts linked above. He’s done a superb job highlighting the problems with this skill, and I feel no need to repeat that task. As daunting as it is to attempt to resolve the problems with perception, I have no qualms about stating quite firmly: perception does have problems.

Pathfinder uses perception in two different ways: one which I’ll call active, another which I’ll call passive. Active perception checks are generally requested by the player. “I’d like to make a perception check to search this room,” or “I’d like to listen intently for someone sneaking up on me.” Active perception checks occur when the character is primarily engaged in the act of looking, listening, smelling, feeling, or tasting. Passive perception checks (sometimes called “reactive”) most often occur without the player’s knowledge. They are rolled by the GM, in secret, to determine whether or not a character is able to perceive something. This might happen when there is a faint scent of cooking coming from behind a door, or if someone is attempting to move without the player’s noticing them. Passive perception checks are useful for information which the players might not be looking for specifically, but which the characters might nevertheless notice and find useful if they’re alert.

Pathfinder is actually pretty vague about when a perception check should be rolled, and what information a player should be able to gain from it. As such, we can’t exactly blame the game for the fact that many GMs and players use it as a substitute for creating & interacting with an actual environment. However, the game would function better if it presented a more focused version of this skill. In the hopes of correcting this oversight, I've broken perception down into its component parts. Below are the various uses I've seen for perception, and my attempts to work out what the skill should apply to, and what it shouldn't.

Active Perception: Primarily used to find hidden treasure, discover secret doors, and avoid traps.

If a room contains treasure, that treasure is either obvious, or not. Obvious treasure, such as that found in a chest, on the body of a foe, or simply laying on the floor, should never require a perception roll to find. So long as the players say they’re searching the body, or opening the chest, they should be allowed to find the treasure.I would hope that was self evident. If a treasure is not obvious, then the players ought to be forced to look for it if they want to find it. The GM should describe the environment the players are in, and if they feel there may be treasure present, they can describe to the GM where they look for it.

What could possibly be gained by having the players roll to discover non-obvious treasure? If their roll succeeds and they find the treasure, then it’s not functionally different from obvious treasure. It simply required the extra step of rolling a die. If, on the other hand, their roll fails and they don’t find the treasure, then the treasure effectively does not exist, because they can’t find it. It’s not as though it’s fun for a player to simply be aware that treasure was hidden before they found it. What is fun is the process of finding that hidden treasure. Coming up with the idea to search for loose bricks on the wall, and being rewarded by finding a bag of 30 gold is a lot more fun than entering a room, rolling a die, and being told you found 30 gold behind a loose stone.

Locating secret doors is somewhat different from finding non-obvious treasure in two important ways. First, the hiding place of even the most well hidden treasure ought to be mentioned in the room’s description. If it’s not, then the players have no way to know where to search That doesn't mean you need to drop obvious hints, simply that it’s not fair to hide treasure under a bed without telling the players that the room contains a bed. On the other hand, secret doors are most commonly built directly into the walls or floors. Since those are present everywhere, there’s no good way for players to search for secret passages intelligently. The second difference is that treasure is an end unto itself. It, along with experience points, is how players are rewarded for successful play. Secret doors, on the other hand, exist only as a means to an end. That end being whatever lies beyond the door. Though the joy of discovery shouldn't be discounted.

Given those differences, I think it is reasonable to allow players to roll perception checks to discover hidden doors. The area for such a perception roll should be relatively small–perhaps 15ft square, centered on the character. Some characters could even be allowed to find hidden doors with a passive perception check, if they passed within 10 feet of it. Traditionally this is an ability which was given to elves, but perhaps it would be better if anyone with 5 ranks or more in perception was given the chance to automatically discover hidden doors. Reducing the act of finding a hidden door to a roll does come with a danger, however. If the entirety of the interaction is rolling to look for a door, finding a door, opening the door, and going through the door; how is that any different from rolling to find non-obvious treasure?

I would propose that a perception roll allows players to, as -C puts it “learn the location of the secret door but not how to open it.” Once they know the door is there, the players are free to attempt to bash it down if they wish. Though in some cases that may be pretty difficult. Alternatively, the players can search for the mechanism within the room which opens the door. Perhaps a loose stone needs to be pushed in, or three worn-down keys on a piano need to be pressed simultaneously. And if the players notice the loose stone or the worn-down keys before they find the door in the first place, then the discovery of a secret passage will be made all the more exciting.

Using perception checks as a means of finding traps is something I've struggled with as of late. My party’s rogue has frequently complained of the tediousness involved in searching every door, every chest, and every trigger that they find in order to avoid the handful of traps in each dungeon. And I have to agree: it is tedious, and not at all fun. I suppose I could make it less tedious by simply adding more traps to my dungeons, but that seems like a lazy solution. The problem is not that there’s an insufficient amount of things to find, it’s that excessive rolling is boring.

Pathfinder has a rogue talent called Trap Spotter, which allows rogues to make an automatic, passive perception check whenever they are within 10ft of a trap. I propose that this be removed as a possible rogue talent, and instead, this effect be made part of the Trapfinding class ability which rogues receive at level 1. Additionally, any character with 5 ranks or more in perception could also be granted the ability to notice traps using passive checks.

Judgement: In general, active perception checks seem to sap potential fun from the game. I propose eliminating active perception checks from the game, except when it comes to searching for secret doors or traps within a 15ft square area centered of the player.

Passive Perception: Primarily used in opposition to a sleight of hand and stealth checks or to notice fine details in an environment.

Sleight of hand may be the single most well-designed skill in Pathfinder, and rolling perception against it is a reasonable method of conflict resolution. There is no need to alter the way in which perception interacts with that skill.The stealth skill, on the other hand, has a number of problems, which I will detail once I write my overview for that skill. Speaking strictly on how perception interacts with stealth, however, I can find no fault. If the stealth roll is being utilized properly, then rolling perception against it makes perfect sense.
That only leaves a roll for noticing fine details in the environment. This is anything which the character’s might not notice right away. A faint smell from two rooms over, an Orc's knee sticking out from behind the barrel he’s hiding behind, or a crack in a stained glass window across the room. I think this application of the skill works well enough. Whenever I go to use it, though, I ask myself one important question: is there any reason to withhold this information?

Using the examples above, it makes sense to roll a passive perception check to see if the players notice the Orc's leg sticking out from behind a barrel. The creature is obviously attempting an ambush, and their success or failure in that attempt will hinge on whether or not the players notice him first. That’s a good use of a roll. It also makes sense to make the roll to determine if the players notice the faint smell of cooking from two rooms over. If they notice it, they have an opportunity to prepare to enter the evil cult’s mess hall, if they don’t then they’ll be surprised when they walk into a room filled with enemies. The crack in the window, however, is essential information if the players are going to figure out the room’s puzzle. If they fail their spot check, then the puzzle becomes unsolvable unless one of them decides (out of the blue) to examine the window for cracks.

Note that you’re not rolling perception based on the type of information, you’re rolling it based on how that information will be used within the game. That may seem silly and unrealistic, and it is. But realism does not equal good game play.

Judgement: Passive perception is mostly fine. Just don’t use it to hide information the players ought to have.

Overall Judgement: I think perception has a valuable place in the Pathfinder game. However, the game benefits significantly from reducing this skill’s importance drastically.

2 move actions / 1 round = 1 look per 3 seconds *20 seconds= 1 minute.

I try never to argue with the judge during a game. it upsets some of them, and often just wastes the time of the other 5 players at the table.

If I recognize that this is the way the judge wants it - I'm ok with that. I just adapt and work with it.

Like in my last game with the (very experienced) judge responded to my request to take 20 on a perception check from the door of a room filled with books and stuff by saying "you know how long that will take?! Hours! checking every 5'square and you have duration buffs going that will expire!" ... talking right over my objection that it would only take a minute... so when I said "all I want to do is take a minute to look around..." "fine you look. And see a bunch of books."

no need to argue... but I feel bad because we are teaching people WRONG. The other people at the table learned that Taking 20 on a Perception check is the same as searching a room and takes hours. And this will happen again, and again at each table that judge runs - and at each table those players play at or run...

So it would be your understanding that it would take two minutes? Ok, I could except that. Though, I would question why it says "...would take (usually 2 minutes for a skill that takes 1 round or less to perform)....". instead of "(..would take (2 minutes for a skill that takes 1 round or less to perform)" dropping the usually.

I think I will use 2 minutes for a skill that only be taken once a round. and use one minute for a skill that can be performed twice a round.... and heck, maybe a round for a skill that can be done 20 times in a round.


I am a big fan of combining spot/listen into a skill, and hide/move-silently. But I think combining spot/listen/search into perception was a Bad Choice; I think passive-spot and active-search should have remained separate skills.

The Exchange

sign... now that this has been moved to "rules questions" board, PFS judges (and players) will likely not see it, so we will continue to be hitting conflict at the table when Judges and players understand this differently.

In a setting outside of PFSOP (in a home game) judges and players can iron this out and will soon both be speaking the same language.

Someone says "Take 10 on a perception check"

one person hears "take a minute to look around..."

Someone else hears "Search the room..."....

this seems to be the issue

Search is not Perception....

A search uses perception just like killing a monster uses an attack skill.

As a GM, I'm always (usually? I'm only human, after all) careful to obtain clarity on what my players want to do with Perception.

If they say "we'll search the room", then I calculate how many squares they are searching, divide by the number of characters involved to calculate the number of rounds it will take, and ask for a roll from each of them

If they say "we thoroughly search the room", same process, but 1 minute per square, no roll because they're taking 20.

If they say "we look around the room", I ask if they're searching, or just looking. One roll per character, one round, they might get lucky on the dice and spot something hidden.

Generally speaking, though, unless something is actively hidden, I'll tell them about it without even needing a roll. Nothing drags down a game like concealing information that the PCs should have just from walking through the room.

I also make a distinction between something that is "hidden" (tucked out of plain view) and "concealed" (in plain view, but either disguised as something else, or one of many similar objects).

A hidden compartment in a desk drawer cannot be spotted by someone standing by the door, no matter how good their Perception skill. Even someone right by the desk won't spot it - they have to search. But a secret door that looks like the rest of the wooden paneling in the room is a different matter: a good enough perception roll could identify it. Likewise, a door behind a bookcase that you have to move out of the way requires searching, but spotting the ledger amongst the encyclopaedia on the bookshelf can be seen from across the room.

That distinction saves me a lot of worries.


I'm sorry but I don't understand this thread.

If a player does not intend to search each 5ft square of a room and a GM interprets that he does, and said GM says "that will take a very long time", that player can simply say "that's not what I'm asking to do".

In fact, any time there is misunderstanding at the table, anybody can go ahead and clarify their intentions.

So what's the issue?

Spotting is a legitimate quick use of the Perception skill. Searching is a legitimate lengthy use of the same skill. Both have their place and the purpose and their mechanism.

I don't know who you're trying to ream here, nosig.


This is why passive perception rules.

You do not have to search every 5 foot square of the room. There is no intent to do that because there is no NEED to do that. The search skill is dead. LOOK at the perception skill. Do you see ANYTHING there about squares? No.

Clarifying your misconception is exactly what the post is about.

There is no need to search the squares. You take 20 and search the entire room, in 1 minute. Done.


You can take 20 and search the entire room from where you're standing in one minute. Range penalties still apply, of course, so if the room is large enough for this to be a potential issue then you may wish to spend a few minutes doing so from multiple vantage points.

There are misconceptions on both sides of this discussion.

Keep in mind that taking 20 on Perception lets you find anything you have line of sight* to, with one roll. There's a penalty for distance, but that is it. One roll searches everything you can see.

Note that the flip side of this means, you need line of sight. Taking 20 on a Perception check does NOT find stuff in desk drawers or behind cupboards, because you'd have to open those things first. So, not every room can be thoroughly searched in 1 minute.

* technically line of effect, but in this case you're probably searching a room using mostly visual senses.

Or you could hand-wave all that stuff and make it one roll instead of:

I search the floor.
I search the floor behind the door.
I search the floor behind the bed.
I search the floor behind the chair.
I search the floor behind the desk.
I search the floor behind the couch.
I search the floor behind the other chair.

You could certainly hand wave the rolls (which you're doing anyways with take 20) but shouldn't time be a factor? Admittedly I haven't studied the perception rules (at least not recently) but a thorough search of the room should take longer than a thorough glance around the room.

So, Search = Overtly precise detailed list that requires an immense amount of time?

Simplifying search is a sin now?

What is the "proper" way, and what does it contribute to the overall fun of all?

I'm not saying a player should have to list every nook and crany but I do feel a search should take longer than a glance.

Yep. Makes trapfinding a breeze too.

If one way is too simple, then how complicated does it need to be?

Seriously asking this.

When and where do we draw that line?


Who said it was too simple? I thought this was a question of how much make believe time it takes to search a pretend room.

Some are asking for a number of additional checks.

Some are just looking to see how time that check/s represents.

As I see it, it would normally take 2 minutes because you are not immobile, you will be moving around to check what is not normally visible from the door.

If you want to stop by the door frame and check the room only from that position, it should take only 1 minute.

The problem is that we have both extremes. People that want to search each nook and cranny, including the drawers content, in 2 minutes without ever entering the room, and GM that will have you spend 2 minutes for each 5' square.

I think that both interpretations are wrong, but I am sure there is people that disagree with me and feel that they are following the rules.


To simplify things, say it takes 1 minute to scan a room from a single vantage point (take 20). If you're going to actually go through drawers and stuff, you'll probably need to figure how many "major features" there are to check (ie. how many cabinets, dressers, desks, rugs, etc). You can check one feature per round (move to search, move to walk to it). I'd say a Wisdom ability check would be in order for this because it isn't about "spotting" things, per say, but being intuitive and wise enough to know to check the desk, check the dresser, check this and that. You know the old adage, "Sure, he can see a fly on the back of a dog at 100 paces, but can he see why kids love Cinnamon Toast Crunch?" So we'll average and say that you divide the number of "searchable features" by 20 and, for every point you net on your Wisdom roll, you were "wise enough" to search that many major features. If there are only 2 features (ie. a Desk and a Rug), and you net a 8 on your Wis roll, you searched the desk but didn't think to look under the rug. 11 or higher means you knew to search both. If there are 20 features, a net result of 8 means you searched 8 of those 20, taking 8 turns (move + open). This will make otherwise non-obvious treasure into obvious treasure. It also determines how long you take. searching 8 things over 8 turns means about 48 seconds. So just shy of a minute to physically go and open the drawers and cabinets, but you didn't think to check under the bed, the rug, behind the painting, etc. If you got a 20, it means you knew to search all 20 features in the room which takes you 2 minutes. Moreover, since this is an Ability Check rather than a Skill Check, there is no fiddling with take 10 or take 20; you're either wise enough to check certain things or you're not.

As I see it, it would normally take 2 minutes because you are not immobile, you will be moving around to check what is not normally visible from the door.

If you want to stop by the door frame and check the room only from that position, it should take only 1 minute.

That's how I'd handle it. 1 minute and you can't find anything not in your direct line of sight with distance penalties. 2 minutes and I'll assume a casual walk through, spotting anything that can be seen. No distance penalties, assuming a reasonable sized area. I might even assume you look in easily openable drawers anc cupboards and under the bed. And let you know what you haven't checked thoroughly.

If a player does not intend to search each 5ft square of a room and a GM interprets that he does, and said GM says "that will take a very long time", that player can simply say "that's not what I'm asking to do".

You do not have to search every 5 foot square of the room. There is no intent to do that because there is no NEED to do that. The search skill is dead. LOOK at the perception skill. Do you see ANYTHING there about squares? No.

Clarifying your misconception is exactly what the post is about.

There is no need to search the squares. You take 20 and search the entire room, in 1 minute. Done.

BNW - I think you are falling into the same trap most people here are...

Repeating the title of the thread "Perception is not Search'.

A Perception check is a skill check. A Player takes this skill check to detect things in his PCs environment. Taking 20 on it means he is doing this check 20 times. He is not searching the room.

A "search" is a group of actions that a PC might do to locate things in an area. There are no precise rules covering what actions are taken in a "search" - I don't think there can be. A PC could "search":
a room,
a prisoner,
a building,
his pocket,
the bottom of the pickle jar...

all these "searches" might use perception checks -

It's kind of like killing a monster. In the action of "killing" there might be a number of "attack" rolls made - just like in a "search" there might be a number of "perception" checks made.

I would like to comment on your statement that I bolded above. I beleave you were meaning "You take 20 and perceive the entire room, in 1 minute."


On the bolded comment? I think you're being pedantic to the point that i have no idea what you're saying. A synonym swap that you seem to take great meaning in and assign great importance to you doesn't seem to change anything at all to me.

Certainly true from a legalistic perspective, but it leaves it very unclear how one actually finds things. If you were GMing and a player said "I'll search the room", what would you do? Correct him and tell him he's perceiving the room with his Perception check? Ignore Perception rolls and play out exactly what he's doing to search the room? Some combination?

It's a thing players want to do and will do. How should it be handled? If the current rules don't handle it, then they should. Currently it seems to be a matter of table variation. Perhaps less here in PFS where DCs are spelled out, often with the conditions for rolling. Even there there is ambiguity: A PC who examines the floor near X with a DC Y Perception check notices Z. Does "I search the room" get you that chance or do you have to specifically say, "I examine the floor near X"?

The problem is that we have both extremes. People that want to search each nook and cranny, including the drawers content, in 2 minutes without ever entering the room, and GM that will have you spend 2 minutes for each 5' square.

I think that both interpretations are wrong, but I am sure there is people that disagree with me and feel that they are following the rules.

I think it's entirely fair to require 1 minute per 5' square that has anything complex to it, basically meaning any feature that would need more than a remote visual scan to search thoroughly. A desk, a wardrobe, a chest, a case of books, whatever. It is obviously impossible to thoroughly search any of these from the entrance to the room. You might notice that the chest is really a mimic that way, but you can't find the hidden compartment in a desk drawer without going to it and searching it close up.

If you were to insist that you could, I'd be imposing some of the modifiers from the Perception list, including the invisible modifier for anything not visually detectable from your vantage point.

I think what he's saying is that when someone announces a Perception check, the listener makes a certain set of assumptions about what's happening based on the rules for the Perception skill; but when someone says they search the room, the listener (i.e., the GM) typically doesn't think about the rules for the Perception skill and instead declares that your PC has just spent an hour walking all over the room, opening doors/drawers, rifling through wardrobes, flipping through books, setting off traps, triggering encounters, and a whole bunch of other things that people visualize when you say "search the room" but that are NOT part of a series of back-to-back Perception checks.


You can charge without charging. You can use two weapons without two weapon fighting. You can use three weapons while two weapon fighting.

The perception skill is used to determine the outcome of your search. True, perception is not search but you can't search without perception.

And clearly the players are not going to state, I try to perceive the desk.

What is the hang up on the word?

Since you FIND concealed doors, hidden doors and traps with Perception, which is what one did with search for quite a long time, I think it is safe to say Perception COVERS Search.

And like all things, the devil is in the details. If it is impossible for the player to perceive something without moving, ask him if he wants to move to get a closer look.

The thing about searching for traps or secret doors with Perception is that, as the article upthread points out, a successful check gives you an idea of what triggers the device and, if you're lucky, some suggestion of how it works. Ex:

The party is coming to a corner in the hallway and the GM knows there's a burning hands trap built into the smoldering wall sconce. If any of the players get close (I'd say within 30' but whatev) if they're looking for those kinds of things I'd have them roll Perception. The trigger on this trap is Proximity (Alarm) meaning anyone who approaches within range of the spell is getting burnt. Therefore successful rolls might indicate only the presence of a weird hum of white noise which grows louder as you approach the trap range. I'd be quick to add though that these PCs don't necessarily "hear" it so much as "feel" the hum adding to the mysterious nature of it all.

Now if someone beat the DC by 5 or more they might also notice very old and faded scorch marks on the walls. These marks seem to indicate a cone of flame originating from the sconce's general vicinity however there's not enough evidence to fully define the exact volume of fire or intensity. Alternatively I might have singed bones laying on the floor or perhaps melted slag and ash in the corner.

Bottom line, they've detected SOMETHING. I don't come right out and say trap or secret door so there's still an element of RP there. Now if the party's trap disarmer has the ability to disarm magic traps and so chooses to step up and attempt to disarm the device I might just compare their take 10 to the trap's DC and describe what happened; alternately I'd have them roll for it and hope for the best.

But if they DON'T try to disarm it, don't have the relevant ability or want to just roleplay it out, let 'em is what I say. I've had players use 10' poles or summoned monsters to set stuff off; I've had other players describe HOW they're inspecting the area and given bonuses or rewarded them with bypass switches. One time I had a player walk up to an open clearing in the woods, roll a Perception check and I told her the clearing floor was covered in dead leaves except for a patch 30' ahead, right in line with the trail.

She asks how much weight she can lift with mage hand, I tell her 5#. She says she grabs a 5# stone, holds it over the spot 15' in the air, then lets it drop to the ground. The trap was a net trap meant to pull victims up into the trees, so I give it to her. She never made a single disarm check and was rewarded for thinking on her feet.

So according to these approaches, to thoroughly search anything you would have to Take 20 (at least 1 minute, possibly 2) Perception check standing motionless in enough different places to get visual coverage of every side of it.
Anything you wanted to open and look inside (drawers, cupboards, small closets,etc) would require another Take 20 Perception check. Lifting rugs? Under the bed?
And you'll have to describe each of these things, so the GM knows where you're looking.

Hopefully, this doesn't extend to a separate check for every book you want to flip through. After all, you can't see inside them all at once from where you're standing. :)

If that's all they've got, then how does the trap guy know whether or not to try to disarm something? How does that even look in-character?

"Hm, there's some burned stuff around here and I can feel a magical humming; maybe if I throw my thieves' tools in that general direction, something good will happen!"

If the guy doesn't know, in-character, that (1) there's definitely a trap, and (2) roughly how said trap works, then what the heck is going on in that character's mind when the player announces "I'll try to disarm the trap, if there even is one"?

The character knows how much time they're spending, and they don't have to T20 at every juncture. So if you walk into a room full of containers of every sort, they're going to have to decide the relative importance of thoroughness versus speed.

(the internet ate my first longwinded reply - trying this again and remembering to do Select All and Copy)

here are the Perception Modifiers listed in the CRB.

Distance to the source, object, or creature +1/10 feet
Through a closed door +5
Through a wall +10/foot of thickness
Favorable conditions1 –2
Unfavorable conditions1 +2
Terrible conditions2 +5
Creature making the check is distracted +5
Creature making the check is asleep +10
Creature or object is invisible +20

But even then, you would be putting a modifier on what? What's the "Search DC" to detect the item... wait, there is no such thing as "Search DC". There is a Perception DC for things... here are examples (again from the CRB)

Hear the sound of battle –10
Notice the stench of rotting garbage –10
Detect the smell of smoke 0
Hear the details of a conversation 0
Notice a visible creature 0
Determine if food is spoiled 5
Hear the sound of a creature walking 10
Hear the details of a whispered conversation 15
Find the average concealed door 15
Hear the sound of a key being turned in a lock 20
Find the average secret door 20
Hear a bow being drawn 25
Sense a burrowing creature underneath you 25
Notice a pickpocket Opposed by Sleight of Hand
Notice a creature using Stealth Opposed by Stealth
Find a hidden trap Varies by trap
Identify the powers of a potion through taste 15 + the potion's caster level

what's the Perception DC to find a note in closed trunk? "...imposing some of the modifiers from the Perception list..." would be odd, as there is nothing to impost these modifiers too, unless the note is rotting, on fire or having "a whispered conversation".

This is because Perception is not Search.

One is a skill, the other is an action. "Search" has not been a skill sense 3.5 changed into PFS. When we use "search" as a synonym of "perception" we are doing both a disservice and mearly confusing the issue.

When a PC does a Perception check from a doorway, he is not "searching the room" - he is trying to detect things from there. A "search of the room" might take longer - or depending on what is being searched for and by whom it might take less than a minute. "Are my car keys in the room?" "No dear, they are in your left hand pocket."

Exactly right!

and worse yet, when the player says "I'll take 20 on a perception check from the door to see what I detect" and the Judge assumes that you are conducting a search of the room (listing your example above) - and proceeds to become upset because .... after all, everyone knows that a Perception check is a search right?

The point of this thread is: "Perception is not Search."

If I am going to search something I might not do a perception check at all.
"I search my backpack for my flask of alchemist fire" -
"that takes a minute" -
"what? it's the only thing in there!"

yeah...
a room,
a prisoner,
a building,
a pocket,
the bottom of the pickle jar...

Search is an action and should be under the control of the judge to decide how long that action takes - depending on a lot of factors.


Basically, what he's saying is that a Perception Check should not, de facto, include walking around the room and opening stuff. It's a "plain sight" search, in police terms. Actually walking around and manipulating stuff is a variety of move actions to get to it, move action again to interact with an object, and a move action a third time to detect hidden or otherwise unnoticeable things inside whatever is being manipulated (ie. secret compartment in the bottom of a drawer, item in a coat pocket in the wardrobe, etc). In other words, look with your eyes, not your hands; using hands is a separate action and not typically subject to a check. You open the drawer; bing bang boom done. Only if the drawer is stuck does it require a Str check. Once the drawer is open, anything obvious is in plain view and easy to spot; you don't need a perception check to see the book and pens in the drawer. But people are using Perception checks improperly; as a shortcut for roleplaying out the searching of a room.

sigh... no, what I am saying is that in "the language of PFS", Perception is a Skill, and Search is an action. They are not the same thing. Perception is not "...It's a "plain sight" search,...". A ""plain sight" search," might use the Perception skill... but might not. And if it does, it might use the skill lots of times, or only once, or not at all....

I did get a laugh from your line..."Once the drawer is open, anything obvious is in plain view and easy to spot;"... clearly you have not seen the drawers in my mothers kitchen! LOL. Also, did you notice that you used the "spot" for a perception check?

I'm not saying "Search" is a synonym for "Perception". I'm trying to figure out what happens if I want to search a room. Using "search" here as a colloquial term not a mechanics one, because it's a real valid thing that characters will want to do.

As I understand your response, the search of the room should always be played out. There is no mechanical shortcut. Anything the players don't mention examining should be ignored, unless it's in plain view from some place where they say they're standing when they make a Perception check. In many cases, to be sure, you'll need to Take 20 on each different line of sight or looking in each container or under each object, all of which you will have to describe opening or moving.
Because there are no mechanics to handle this.

That's a flaw in the system. There should be mechanics to handle it.

As for your backpack example, your GM shouldn't make you Take 20 without you asking. Finding a single flask in an otherwise empty pack should be a DC1 or 2 check. Move action. Don't bother rolling. :)

Trying to answer my view on:"I'm trying to figure out what happens if I want to search a room. "

You turn to the judge and say: "I want to search this room, the one you just described with the trunk in the corner and the bed against the wall over there. We've got plenty of time and we do a good job of it."

The judge decides that a full search will take 10 minutes and nets a Perception check for the one item to find in the room (note hidden in the binding of a book under the pillow on the bed. The DC to locate the note is 25... but he feels that a PC would have to have the book in sight to have a chance of detecting it (as it is only detectable by sight). So he either asks the player for a Perception check, makes it for the player himself, or considers the PC to be takeing 20 on a Perception check (as they said they had plenty of time and would "...do a good job of it".

Game time used for the mechanics - maybe 5 minutes? maybe less?

in the next room the players give the same instruction...

The judge decides that a full search will take longer as the room is more cluttered, so 20 minutes and there is nothing of note in the room but they checked and they "...do a good job of it".

in the third room the players have a fight with the monster that they might have detected with a perception check from the door, and then give the instruction that they are searching the room...

The judge decides that a full search will take 10 minutes again and adds a few more to search the bodies. There are three things of note in this room and two will get a Perception check to find them, but one is a body in a trunk in the room and is found during the search (no perception check).

does this answer your questions?
