You have learned to draw a weapon and attack a foe as one quick action.
Benefit: As a standard action you can draw a light weapon and attack one target with it. Rather than make a standard attack roll, make a Sleight of Hand check. If your skill check exceeds your target’s AC, your attack hits. If your skill check also exceeds a DC of 10 + the target’s base attack bonus + the target’s Wisdom modifier (or 10 + your target’s Sense Motive bonus, whichever is higher), your target is also denied its Dexterity bonus to AC against this attack. Any given target may be the target of your Knife Trick only once per day.
