Check: 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.
Favourable and unfavourable circumstances weigh heavily on the outcome of a bluff. Two circumstances can weigh against you: the bluff may be inherently hard to believe, or the action that the target is asked to take may go against its self-interest, nature, personality, orders or the like. If the difference is important, you can distinguish between a bluff that fails because the target does not 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, the target did not 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.
A successful Bluff check indicates that the target reacts as you wish, at least for a short time (usually one round or less) or believes something that you want it to believe. Bluff, however, is not a_ domination_ spell.
A bluff requires interaction between you and the target. Creatures that are unaware of you cannot be bluffed.
Feinting in Combat: You can also use Bluff to mislead an opponent in melee combat to prevent him from dodging your next attack effectively. To feint, make a Bluff check opposed by your target’s Sense Motive check. 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, the target is unable to dodge or parry 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 non-humanoid is difficult because it is harder to read a strange creature’s body language; therefore, you take a –4 penalty on your Bluff check. Against a creature of animal Intelligence (1 or 2) the task is even harder; you take a –8 penalty. Against a nonintelligent creature, feinting is 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 Stealth 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. The DC is 15 for simple messages or 20 for complex messages, especially those that impart new information. Failure by four or less means you cannot get the message across. Failure by five or more means that you have accidentally implied false information, or the receiver has inferred the same. 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.
Action: Varies. A Bluff check made as part of general interaction always takes at least one round and is at least a full-round action, though 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 does not take an action; it is part of normal communication.
Try Again: Varies. Generally, a failed Bluff check in social interaction makes the target too suspicious for you to try again in the same circumstances, though 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 only be attempted once per round. Each retry carries the same chance of miscommunication.
Special: If you have the Persuasive feat, you get a +2 bonus on Bluff checks.
