Twist the Knife

(Exemplars of Evil, page , DnD 3.5)

[General]

You can make a vicious attack that leaves your victim gasp- ing in pain.

Prerequisite

Improved Critical (melee weapon), Sneak attack +2d6

Benefit

Benefit: Whenever you confirm a critical hit while wielding a melee weapon for which you have the Improved Critical feat, you can forego the extra damage and wrack the target with pain instead. For a number of rounds equal to the weapon's critical multiplier, the target takes a --3 penalty on attack rolls, weapon damage rolls, saving throws, ability checks, and skill checks.
