Bluff (Cha)

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.

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 self-interest, nature, personality, orders, or the like. If it’s important, you 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.

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.

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. 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).

Action

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.

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, 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.

Special

A ranger gains a bonus on Bluff checks when using this skill against a favored enemy.

The master of a snake familiar gains a +3 bonus on Bluff checks.

If you have the Persuasive feat, you get a +2 bonus on Bluff checks.

Synergy

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.

Epic

The character can implant a nonmagical suggestion in a target, display a false alignment, or disguise his or her surface thoughts.

Instill Suggestion in Target

This is identical to the effect of the suggestion spell, except that it is nonmagical and lasts for only 10 minutes. It can be sensed as if it were an enchantment effect (Sense Motive DC 25).

Display False Alignment

The character can fool alignment-sensing effects by displaying a false alignment of his or her choice. Once set, a false alignment remains as long as the character remains conscious and awake. Setting or changing a false alignment requires a full-round action.

Disguise Surface Thoughts

The character can fool spells such as detect thoughts (or similar effects) by displaying false surface thoughts. While the character can’t completely mask the presence of his or her thoughts, he or she can change his or her apparent Intelligence score (and thus the character’s apparent mental strength) by as much as 10 points and can place any thought in his or her “surface thoughts” to be read by such spells or effects. If a character attempts to use Sense Motive to detect his or her surface thoughts (see the Sense Motive skill description), this becomes an opposed check (though any result lower than 100 automatically fails).
