(Player's Handbook v.3.5 variant, p. 67)
You can make the outrageous or the untrue seem plausible, or use doublespeak or innuendo to deliver a secret message to another character. The skill encompasses acting, conning, fast talking, misdirection, prevarication, and misleading body language. Use a bluff to sow temporary confusion, get someone to turn and look where you point, or simply look innocuous.
A Bluff check is opposed by the target's Sense Motive check. See the accompanying table for examples of different kinds of bluffs and the modifier to the target's Sense Motive check for each one.
|Example Circumstances||Sense Motive Modifier|
|The target wants to believe you.||—5|
|"These emeralds aren't stolen. I'm just desperate for coin right now, so I'm offering them to you cheap."|
|The bluff is believable and doesn't affect the target much.||+0|
|"I don't know what you're talking about, sir. I'm just a simple peasant girl here for the fair."|
|The bluff is a little hard to believe or puts the target at some risk.||+5|
|"You orcs want to fight? I'll take you all on myself. I don't need my friends' help. Just don't get your blood all over my new surcoat."|
|The bluff is hard to believe or puts the target at significant risk.||+10|
|"This diadem doesn't belong to the duchess. It just looks like hers. Trust me, I wouldn't sell you jewelry that would get you hanged, would I?"|
|The bluff is way out there; it's almost too incredible to consider.||+20|
|"You might find this hard to believe, but I'm actually a lammasu who's been polymorphed into halfling form by an evil sorcerer. You know we lammasu are trustworthy, so you can believe me."|
Favorable and unfavorable circumstances weigh heavily on the outcome of a bluff. Two circumstances can weigh against you: The bluff is hard to believe, or the action that the target is asked to take goes against its selfinterest, nature, personality, orders, or the like. If it's important, the DM can distinguish between a bluff that fails because the target doesn't believe it and one that fails because it just asks too much of the target. For instance, if the target gets a +10 bonus on its Sense Motive check because the bluff demands something risky, and the Sense Motive check succeeds by 10 or less, then the target didn't so much see through the bluff as prove reluctant to go along with it. A target that succeeds by 11 or more has seen through the bluff (and would have done so even if that bluff had not entailed any demand).
A successful Bluff check indicates that the target reacts as you wish, at least for a short time (usually 1 round or less) or believes something that you want it to believe. Bluff, however, is not a suggestion spell. For example, you could use bluff to put a shopkeeper off guard by saying that his shoes are untied. At best, such a bluff would make the shopkeeper glance down at his shoes. It would not cause him to ignore you and fiddle with his shoes.
A bluff requires interaction between you and the target. Creatures unaware of you cannot be bluffed.
Feinting in Combat: You can also use Bluff to mislead an opponent in melee combat (so that it can't dodge your next attack effectively). To feint, make a Bluff check opposed by your target's Sense Motive check, but in this case, the target may add its base attack bonus to the roll along with any other applicable modifiers. If your Bluff check result exceeds this special Sense Motive check result, your target is denied its Dexterity bonus to AC (if any) for the next melee attack you make against it. This attack must be made on or before your next turn. Feinting in this way against a nonhumanoid is difficult because it's harder to read a strange creature's body language; you take a —4 penalty on your Bluff check. Against a creature of animal Intelligence (1 or 2) it's even harder; you take a —8 penalty. Against a nonintelligent creature, it's impossible. Feinting in combat does not provoke an attack of opportunity.
Creating a Diversion to Hide: You can use the Bluff skill to help you hide. A successful Bluff check gives you the momentary diversion you need to attempt a Hide check while people are aware of you. This usage does not provoke an attack of opportunity.
Delivering a Secret Message: You can use Bluff to get a message across to another character without others understanding it. Two rogues, for example, might seem to be talking about bakery goods when they're really planning how to break into the evil wizard's laboratory. The DC is 15 for simple messages, or 20 for complex messages, especially those that rely on getting across new information. Failure by 4 or less means you can't get the message across. Failure by 5 or more means that some false information has been implied or inferred. Anyone listening to the exchange can make a Sense Motive check opposed by the Bluff check you made to transmit in order to intercept your message (see Sense Motive, page 81).
Varies. A Bluff check made as part of general interaction always takes at least 1 round (and is at least a full-round action), but it can take much longer if you try something elaborate. A Bluff check made to feint in combat or create a diversion to hide is a standard action. A Bluff check made to deliver a secret message doesn't take an action; it is part of normal communication. However, the DM may limit the amount of information you can convey in a single round.
Varies. Generally, a failed Bluff check in social interaction makes the target too suspicious for you to try again in the same circumstances, but you may retry freely on Bluff checks made to feint in combat. Retries are also allowed when you are trying to send a message, but you may attempt such a retry only once per round. Each retry carries the same chance of miscommunication.
A ranger gains a bonus on Bluff checks when using this skill against a favored enemy (see page 47).
The master of a snake familiar (see the Familiars sidebar, page 52) gains a +3 bonus on Bluff checks.
If you have the Persuasive feat, you get a +2 bonus on Bluff checks.
If you have 5 or more ranks in Bluff, you get a +2 bonus on Diplomacy, Intimidate, and Sleight of Hand checks, as well as on Disguise checks made when you know you're being observed and you try to act in character.
