Player's Handbook v.3.5 (PH)3.5

Key Ability: CHA
Trained Only: false
Armor Check Penalty: false

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.
