Your strikes render your target temporarily clumsy and awkward.
Prerequisite: Sneak attack +4d6.
Benefit: Your successful sneak attack imposes a -2 penalty on the target's Strength and Dexterity checks, as well as on any Strength- and Dexterity-based skill checks, for 10 rounds. If you use this feat a second time on a target before 10 rounds have elapsed, the effect of the first use expires.
Using this feat reduces your sneak attack damage by 3d6.
