Bluff is one of those skills that is easy to use. In nearly any situation a Bluff check can be made to gain some benefit. Using the skill in combat costs you an action, but out of combat a Bluff is made within normal talking or other forms of communication. If you are interacting with any character consider if you are attempting to motivate them, and if you are; Bluff them. You don't have to be falsifying to make with a Bluff check.
Bluff Does Not Lie
Bluff is simultaneously one of the most used skills, and one of the most misused skills, RAWise. It is written that the Bluff skill does not let you lie, but in countless games a lie calls for a Bluff check. It is not surprising that Bluff is often misused, it is a skill with allot of utility. It is easy to take the skill one step farther, to the point of actual taking care of deception for you. The skill that would most realistically be checked to cover the details of lying would be Perform (Storytelling), however lying is not an action that is managed by a skill check. You simply tell the truth or you don't. An NPC believes, or disbelieves, what you say based on what that NPC knows.
A Diplomacy check could make the NPC feel helpful enough to believe you, but a Bluff check will convince the target of the importance of the information, regardless of truth. Bluffing is a motivational action that relates to, but does not actually include, deception. You can make a Bluff check to give persuasion to a lie, "... and there are riches in it for you ..." is a lie to make them want to believe you. A Bluff check is ironically the skill check used to gauge the communication of the greatest truths, Innuendo (oh, I mean Delivering a Secret Message). A successful Bluff check conveys belief in something, a belief about something about you. What you mean, what is important to you, or what you are going to do.
The Feint
The feint function is one of the finest combat injections to the mostly non-combat social skills system of D&D. Feints are fully functional in combat. Use them, you'll see. If you have Bluff ranks, and your enemies are quick with a low BAB, you don't really have to try to hit them. Power Attack on a feint. The feint, like the attack roll, is not one quick dart to the left. Fining involves a complex series of movements. The dramatic backhand swing, is a gorgeous example of a feint in combat. Improved feint, best for melee capable rogues and bards, gives you a total turn attack pattern as a pseudo full attack action.
A fighter with improved feint, and at least a few ranks in Bluff presumably, will have a two turn attack pattern. First round power attack (or other single attack action, perhaps even aid), and a feint. Second round Full-Attack. Third round repeat. Improved feint turns the fighter into a one-two punch mechanical killing machine. Pair fighter levels with rouge, one for one (no XP penalty), and you eventually end up with a thing that can dance through fireballs (evasion), through infantry (tumbling), past your opponents guard (feint), hit him (3/5th attack bonus), and steal the key off his neck (slight of hand).
Pairing with fighter levels with bardic can create a potent field commander, slightly spendy with bardic music uses though. A fighter/bard can't really afford to spend the entire fight singing. The pattern is more flexible. He uses a strike-feint-full-attack one-two, but takes third or fifth turns off to make with the inspiration. In a single combat scenario, with a few bard levels under the character's belt, this pattern keeps the entire party attacking at a higher success rate. Yourself even more so because you are using improved feint. The charismatic bard, or any other character, should not take their score modifier for sufficient when it comes to Bluff. To maintain the fin's utility in combat you must put ranks into the skill to counter act the rising resistance of base attack bonus.
A feint takes the base attack bonus of a target into account when being resisted. Bluff is the only combat useful skill to do this. The simple reason is that the combat instincts of the target are motivating that target to disbelieve you. A feint really is a form of lie actually; you are implying an action that you are not going to do. The subtle difference here is that the feint is a microburst of miscommunication. Your target knows you are trying to hit them, you are really only lying about where. For the rouge/bard the fascinate sneak attack pattern is like "super feint," but it really only works once at the beginning of combat. Feint, improved or otherwise, allows you to make single move maneuvering though combat an effective tactic. Move, feint, disarm, move, feint, trip, move, feint, sneak attack from flank.
A Quick Diversion
Hiding can save your life, and if you have a sneak attack that diversion could lead to massive damage dealt by you. As far as modifiers, remember that the target may want to believe that you have left, but probably finds your disappearance unlikely. A NPC that is hunting you in particular probably doesn't want you to take a powder, but is more likely to belive that you ran away. Creating a diversion to hide does not take attack bonus into account so besides the normal Bluff modifiers the check is pretty easy. Sense motive is a skill that low level NPCs rarely take ranks in. Intelligent, or wise, NPCs are, of course, each a unique story.
Delivering a Secret Message
When you really want to tell a character something, and you want the target to understand, use Bluff to deliver a secret message. Bluff lays a DC on intelligible communication; complex DC 20 and simple DC 15. Were you into rolling allot of dice, Bluff could be taken as the skill of simply talking. When you want to tell an NPC something, anything, roll Bluff. Your success or failure on the skill and rank modified d20 roll determines how well the NPC receives the intent of the message you role play. Delivering secret messages this way implies that you are only ever really talking to one person at a time. Everyone else has to make Sense Motive checks to get in on your one-on-one jive.
In that sense the Bluff check is the skill check of actual inter-character communication. NPC to NPC, PC to NPC, even PC to PC. Diplomacy deals with general attitudes, and Perform lets you touch the hearts, and money pouches, of many; but Bluff is the skill you can use to tell one target what you want that target to know, and have rules for failure. Unlike a standard Bluff check delivering a secret message translates only information. Oddly, the general function of Bluff, when not using one of the subfunctions, is made with the consideration that the target already knows what you are saying. You are making the Bluff check to use the knowledge the NPC already has to motivate that target do want to do something. Technically delivering a secret message is only needed to conceal what you are saying to a target from listeners. You don't have to make a skill check to tell someone something, just like you don't need to make a skill check to lie.
Why Sense Motive
The mighty resistance skill of Sense Motive appears often in the description of Bluff. Every function of Bluff is resisted by Sense Motive. Primary purpose, feint, diversion, and deliver all have a relationship with Sense Motive. This relationship can be likened to the BAB and AC relationship. Charisma is like strength; adding punch to the attack. Wisdom is like Dexterity; assisting with evasive maneuvers. Intelligence analogizes to Constitution making Skill Points Like HP. Of course, you don't loose Skill Points dynamically the way you do HP, so that's the break in the analogy. Another is that Sense Motive is Bluff's big evil bad guy. Always able to frustrate Bluff until the very last feinted turn.
Now Let Me Tell Ya
No one needs an explanation of what the Bluff skill, does. Sometimes you need to be reminded of what the Bluff skill don't do. So I made sure to tell you first thing, if you'll notice. However, you will be using the Bluff whenever you lie, because you don't lie unless you want somebody to do something for you. Go away! Do this! Do that! Whatever, but, remember to Bluff when telling the Truth too. If you want someone to take an action on your behalf, regardless of the veracity of what you are saying, Bluff! That is my secret message for you.
Did the rest of ya'll hear that!
Shea's Research & Development (SR&D
What Does Bluff Need?
"Not much," I'd say. Bluff is already a paragon of a skill. It is flexible in and out of combat. To say that it is under used would be a lie. Bluff can however be slightly modified based on conceptual lines. Not for utility, but for the sake of reality. Using Bluff in the following ways may enable you to save a few skill points too, if that is what you need to do. Basically, the real question is: where do you draw the line?
How About an Example?
This is me bluffing you:
You need to change the way you use the Bluff skill. Honestly. When analyzed as part of the whole set of social skill functions Bluff is an oddity. Half communication, half deception, and hard to conceptually separate from negotiation. Too much work for you? Just read up on the below.
Bluff and Social Skill Functions Like Negotiation
The premise of Bluff is in that motivational feeling you can produce. So Bluff as a performance. How about motivating an attitude. Bluff as Diplomacy. Talk that street talk? Bluff as Profession too. Why is Diplomacy the skill of negotiation? Why not Bluff? Why not both? "I like the way you negotiation" says the fast talking man. If you include Bluff into a general negotiation function, then you should pull in Intimidation too. How do you make a bargain sir? By reason, silver tung, or force? These skills could mix and mingle with Bluff as easily as Sense Motive does.
You could also, maybe, just use Bluff to resist Bluffs. Stick with me here, but the ability to fast talk could be seen as the ability to resist the very tactics you know how to use. You can't fool an old con, they say. You would be creating a sort of Bluff battle. Corollary to a grapple, Bluff battles would continue, the upper hand changing throughout perhaps, until the winner has the loser clearly in a pinned in a conceptual corner and reasonably beaten, or both parties give up. This, however, sounds allot like a negotiation. Now, this might send Sense Motive the way of the dodo, but you could treat all general Bluffs as a form of negotiation. Opposed by Bluff, Diplomacy, or Intimidation.
If you take Sense Motive away this way you need other ways to defend and detect the sub functions of Bluff. Beyond your BAB what else do you need to resist a feint? As far as hiding and delivering a secret message? Why not just let those stay spot and listen checks? If you add the modifiers from the Bluff skill to the resisting wisdom based sense roll the numbers are sufficiently skewed to represent the more complex conceptual situation. In the case of creating a diversion to hide a character would receive two spots. One based on the diversion, and one based on the Hide.
The Cold Hard Line
Bluffs, like the other social skill checks in the game, are not spells. The target character is under no abnormal compulsion to do anything they would not normally do. Bluff, the paragon of effective social skills is really no more able to force action than a knowledge skill. Bluff has this eerie reality to it in that only with an epic modifier of +50 to the DC are you able to actually know that what you said is going to motivate a target to do anything. Remember to make it brief; you got ten minutes. If you are not satisfied with this; there is a down and dirty way to fix it.
Use Bluff to set a will save DC (and there went Sense Motive). You should definitely give the will save all appropriate morale modifiers and apply the circumstantial modifiers listed in the skill description of Bluff. If you don't anybody with Bluff will be able to tell everyone within five levels of them what to do by taking ten. The compulsion functions like a mental poison. A character receives an initial save to resist the compelling idea, and then a secondary save right before they do what they are compulsed. Any Bluff that the target would consider harmless and acceptable should not be rolled because that means the NPC already wants to do it, eh?
Procrastination is allowed with this compulsion, but once the compulsion is unstilled you may reinforce it with an subsequent Bluff check. Reinforcement prompts another will save and resets the secondary save to the result of the reinforcement Bluff check. If the target fails the reinforcement save the target immediately sets out to satisfy their compulsion. With this system remember that the source of the compulsion is non-magical, and, more importantly, you. Removing you from the equation brings the compulsion to an end. My message? Be wary of negotiating with the Evil or the Cruel.
There are a number of variant systems available that add modifiers to social skill rolls based on the current attitude or degree of familiarity a character has with their target. Any and all of these are acceptable modifiers when determining a Bluff set will save DC. The message behind that eerie epic reality is that it should not be easy to motivate a target to do something that they don't want to do. If the modifiers are all in your favor, instead of familiarity mitigating the danger involved or some such, then you should consider if Bluffing is actually necessary. Sometimes all you have to do is explain something to a character to motivate them. If you find this the case, when reviewing the modifiers, consider making a Knowledge check instead.
To get rid of a compulsion a Bluff, Diplomacy, Heal, Intimidation, or Profession check can be made on the compulsed character. The function mimics the way that Heal treats poison. A concerned assistant, or king's attendant, can substitute their skill roll for the compulsed character's will save. Unlike poison, the effects are immediate. You either succeed at talking the target out of the idea or you don't. You don't have to wait until the last moment to find out if the treatment worked. Of course, the target is free to Bluff you back that they are still under the influence, but that is degenerating into the realm of what metagame the players are playing.

Spending Money on Bluff
Bluff is not a skill that you need allot of stuff to use. Bribery is always an option, but that gets back into the realm of negotiation. As a common rule you could set a + 1 circumstance bonus to Bluff per 10gp spent on bribery, but when Bluffing the excessively rich, 10 gp is a pittance. Depending on the social strata you are maneuvering on you may need 100, or 1,000 gp per + 1 circumstantial modifier. Equipment given as gifts should be valued with some consideration for who the gift is given to. A promise really comes in handy with a Bluff, but a promise costs you nothing, at least in gp. Perhaps perfume ranging from 1 to 100 in gp value could grant you a + 2 under the right circumstances, but, for Bluff, equipment really doesn't help you.
A note about lying, it really helps to have proof. Bluff motivates, but skills like craft and forgery allow you to make objects that "confirm" your story.

Bluff Does Not Lie
Bluff is simultaneously one of the most used skills, and one of the most misused skills, RAWise. It is written that the Bluff skill does not let you lie, but in countless games a lie calls for a Bluff check.
Sorry, but I have to disagree with you here. Bluff does represents the ability to lie effectively. It's the first line of the skill: "You can make the outrageous and untrue seem plausible." Where do you see it written that Bluff isn't about lying? A plausible lie ("I'm from Boston," when you're actually from New York) may have a big bonus to the Bluff check, or at least no penalty. An average person lying to another average person would have about a 50/50 chance of being believable. That seems about right.
I'd say it's fine for the DM to rule that some bluffs are too inconsequential to bother with a check -- in the example above, it may not particularly matter where you're from, if you're just trying to pick up a girl in a bar. But if you're lying to the police, for example, you certainly should make a check! D&D is a cinematic game, after all. You don't make checks for lies that don't matter, just like you don't make ride checks to just sit on a horse. The checks are reserved for risky situations.
It is not surprising that Bluff is often misused, it is a skill with allot of utility. It is easy to take the skill one step farther, to the point of actual taking care of deception for you. The skill that would most realistically be checked to cover the details of lying would be Perform (Storytelling), however lying is not an action that is managed by a skill check. You simply tell the truth or you don't. An NPC believes, or disbelieves, what you say based on what that NPC knows.
Not at all. Whether a lie is believable depends hugely on the glibness and body language of the liar. Some people are naturally good at lying -- they can look you right in the eyes and lie without flinching. Other people just can't do it. It's true that you "either tell the truth or don't", but whether your audience buys the lie or not is what a Bluff check is all about!
Check out the table of Bluff Examples. I mean, it's one thing to say "These aren't the druids you're looking for," but it's entirely another thing to say it with confidence and poise that convinces the guards that these aren't, in fact, the druids they want.
I've found that what most people get wrong is that the bluff skill is not "Charm lite" or anything of that nature. A successful bluff check means the target believes your claim, but does not force it into any particular course of action. Depending on the bluff, they may do something based on believing what you said, but that isn't the same thing.
You can't, for example, walk up and bluff somebody into buying something. You can bluff that a worthless item is a powerful artifact, or you can bluff that these gems aren't stolen. But if the person wouldn't buy them from you anyway, you aren't going to make a sale. If they're a gem merchant, they might buy the jewels, though, because that's what they do.
Generally, you'd want to combine a bluff check with a diplomacy or intimidate check -- bluff to get them to believe a fact, then the other two skills to direct their actions based on that belief. For example, bluff could be "I am an important official of the King; I'm wearing rags because I was assaulted and robbed." Then, once they've bought that, they may let you in the door, or you may have to make an intimidate check or diplomacy check to get them to move -- the same as a real official would have to make when the King ordered "Let nobody in this door". You say, "If you don't let me in, I'll make sure the king locks you in the dungeon!" That's intimidate. The bluff facilitates the intimidation, but doesn't force the guard to take action all on its own.
I do have one question, though, how does the Feint Flurry Feat work exactly?
Feint Flurry [COMBAT]
Prerequisite: Base Attack Bonus + 13, Improved Feint, Flurry of Blows.
Benefit: You may feint an opponent and ignore their Dexterity bonus to AC for an entire full attack round.
Normal: A feint only allows you to ignore a target's Dexterity bonus to AC for a single attack.
Special: If you do not start your full attack with your next available action the feint is wasted.
Improved Feint allows feinting as a move action, but since (outside of Psionics) you can't combine a move action with a full attack, how is this feat intended to be used? A character would have to take a standard action to attack(or a move action to approach), then a move action to feint, and in the next round, take a full attack action.
It seems tricky in practice to me, since it relies on your opponent staying within 5' of you. Also, who could use it? For fighters, it's rarely needed, since so few monsters have big dex bonuses, and for monk/thieves, you'd almost have to be epic just to get the BAB.
Sorry, but I have to disagree with you here. Bluff does represents the ability to lie effectively.
I agree and stated as much in the article.
It's the first line of the skill: ... That seems about right.
Again, thats right. Having several ranks in bluff will make you better able to lie, about anything. Assuming thats what you do with it.
I'd say it's fine for the DM to rule that some bluffs are too inconsequential to bother with a check -- in the example above, it may not particularly matter where you're from, if you're just trying to pick up a girl in a bar. But if you're lying to the police, for example, you certainly should make a check! D&D is a cinematic game, after all. You don't make checks for lies that don't matter, just like you don't make ride checks to just sit on a horse. The checks are reserved for risky situations.
Correct again, when it doesnt matter there is nor real need for a check. I would say that sometimes it "doesnt matter" and its fun to roll dice anyway - this is a dice game. Drinking contests between players.. not needed "so you two have a drinking contest and his con is better so he wins ... and that night"
Basically what are you saying? Are you saying that I said you dont roll bluff when you lie? No, I said you will always be rolling bluff when you lie. I just also said that bluff is not the "skill of lying."
Some people are naturally good at lying -- they can look you right in the eyes and lie without flinching. Other people just can't do it. It's true that you "either tell the truth or don't", but whether your audience buys the lie or not is what a Bluff check is all about!
People that are bad at lying are generally bad at telling the truth too. They are bad at giving public discourse, and they are bad at being the center of attention. Bluff is all about convincing people of something, and anytime you are lying you are convincing someone of something that they have reason not to believe. What reason? All the reasons in the world - everything thats right and true should contradict you.
Check out the table of Bluff Examples. I mean, it's one thing to say "These aren't the druids you're looking for," but it's entirely another thing to say it with confidence and poise that convinces the guards that these aren't, in fact, the druids they want.
Here is a good point in your favor - "bluff" by deffinition is a lie, and by deffinition I mean websters. Its a technique used in gambling - pretending to have an advantage. When you really do have an advantage - they say "and he wasnt bluffing!" So I can see how that is really sticking with you past the technical value presented with the skill.
A successful bluff check means the target believes your claim, but does not force it into any particular course of action.
That is charm lite... dude. All charm does is make your target believe you and him are freinds. (offa memory... ) Something along the lines of - charm does not give you control of a character, they simply behave as though you were a good friend and ally. If your real allies attack your new "freind" they will not attack them. You will simply treat them as though they were attacking a member of the party. Or something along that line. Really the actual charm spell is just a magic diplomacy check - one that the target actually gets to resist.. never thought about it in that exact frame of refrence before.. thanks.
You can't, for example, walk up and bluff somebody into buying something.
The rules may not let you (here we disagree), but you certainly can. See how well you roll your "sense motive" check when the kirby man comes to your door. Every thing he tells you will be true. Everything, but you will still not want, and want to buy the machine. You want to buy it because its a wonder of modern science, and you dont want to buy it because its flippin expensive. You know this (if you know anything about the kirby) before you start the conversation, but the question is whether you are gonna buy it now.. and from that guy. No lying, all bluff. No other skill in the game covers high pressure sales.
Generally, you'd want to combine a bluff check with a diplomacy or intimidate check -- bluff to get them to believe a fact, then the other two skills to direct their actions based on that belief.
Diplomacy and Intimidate !?! Are you kidding me? Diplomacy changes attitude.. THATS IT! What kind of "directions" are you supposed to give with that? Intimidate.. yeah you know what your talking about. Nothing like a screaming fit in the middle of a good scam to send the whole thing sour.
For example, bluff could be "I am an important official of the King; I'm wearing rags because I was assaulted and robbed." Could indeed Then, once they've bought that, they may let you in the door, or you may have to make an intimidate check or diplomacy check to get them to move -- the same as a real official would have to make when the King ordered "Let nobody in this door".
Umm(two year old voice) Why?
Once you have used bluff to get them to "buy it" (see above regarding irony) they should probably go ahead and treat you like a noble from then on. Id say that if any more checks are needing to be made - they are more bluff checks. Every time you make a slip - bluff to cover. Every time you miss actually get close to your real aim (your stealing something right? and you see it in the middle of dinner with the king) bluff to cover. Diplomacy if you want the people to be your friends - a good idea .. freindlies tend to give you the benefit of the doubt. Intimidate if you want to .. hostiles tend to avoid you SO you are less likely to have to deal with them bothering you.
Now, either one could come in handy in a good scam, and Intimidate particularly since hostiles are more likely to believe anything bad about you. Thusly making it easy to insinuate whatever personal grudge or particular bad taste you want - so long as it covers your actual aim. Feindlies on the other hand want to flippin "help" you, and when your actual goals are not what they seem.. help can be very frustrating.
You say, "If you don't let me in, I'll make sure the king locks you in the dungeon!" That's intimidate. The bluff facilitates the intimidation, but doesn't force the guard to take action all on its own.
Now, I see how that applies.. but I must point out - that was a lie. "Ill make sure the king locks you in the dungeon" the old "do you know who I am" is (in this example) an actual factual 100% lie. So why arent you rolling Bluff there? Bluff is the lie skill. You are rolling it when you are lying so why not there?. Bluff is not the lie skill. It is the "convince" skill. The "scam" skill. The "insinuate" and the "instigate."
From our conversation I can tell you something about yourself Keenath. Your not a good liar. You believe youself too much. A scam artist; The Con, if you will, is the master of truth in lies, and lies in truth. Ask any good liar and they'll tell the the facts: The best lie is the little lie. The lie that "floats on a ocean of truth." The single scrap of misinformation dropped at percisly the right time, such that the three things said before were undeniable, and the last several are too, SO why bother to check on that one in the middle?
Bluff like all D&D skills is a check that you win or loose. Unique amongst them in that the modifiers give a grey zone. Fail by less than 10 on a check to "convince a dozen 1st level fighters they need to go fight the orc hoard with you" and they believe in the orc hoard, but dont want to go with you. A succeess in your deffinition of the skill - they believe you, but a fail by RAW and shea's deffinition - you missed the DC and you didnt "motivate" them to do anything about it.
Basically what Im saying is "convince a dozen 1st level fighters they need to go fight the orc hoard with you" is a bluff regardless of truth. In allot of cases a Diplomacy will create a scenario where they could go with you, or they might just wish you luck and give you some provisions on your noble quest. Intimidation - yeah keep your eye on em, they gonna get hostile eventually. Bluff makes the target believe what you want them to, and like a wish (as in phrasing is important here) "You have to come with me" is a belief more motivating than "You will treat me as freindly."
