You can use slang and suggestive gestures to pass secret messages openly.
Prerequisite: Bluff as class skill.
Benefit: Your subtle cunning allows you to use the secret messages application of the Bluff skill in three additional ways. First, your attempts to pass a secret message of no more than 15 words may be done a free action rather than a full-round action (though you may only do so once per round). Second, characters take a –5 penalty to Sense Motive checks when attempting to decipher your secret messages. Third, any time you attempt to send a secret message to another character who has the Thieves’ Cant feat, there is no chance of the message being misunderstood by the recipient.
