Sap Master (Combat)
You knock the sense out of foes with a well-timed surprise attack.
Prerequisites: Sneak attack +3d6, Sap Adept.
Benefit: Whenever you use a bludgeoning weapon to deal nonlethal sneak attack damage to a flat-footed opponent, roll your sneak attack dice twice, totaling the results as your nonlethal sneak attack damage for that attack.
