Description: Your hands can move so quickly that observers don't see what you've done.

Prerequisites: DEX 19

While under direct observation, you can make a Bluff check as a move-equivalent action, opposed by the Spot checks of any observers. If you succeed, your misdirection makes them look elsewhere while you take a partial action. If your partial action is an attack against someone who failed the opposed check, that opponent is denied a Dexterity bonus to AC.
