Knockout Artist (Feat)

You can throw devastating knockout punches.

Prerequisites: Sneak attack class feature, Improved Unarmed Strike.

Benefit: When you use your unarmed strike to deal nonlethal damage and sneak attack damage to an opponent denied his Dexterity bonus to AC, you gain a +1 bonus on the damage roll per each sneak attack damage die you roll.

Special: this bonus will stack with Rogue feats and talents that improve sneak attack damage.
