Vivisectionist Stance (3.5e Maneuver)

''To properly understand your opponent you must understand them from the inside out. Let's begin with the inside...''

While you are in this stance you deal 1 point of precision damage per initiator level whenever your target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the initiator flanks their target. This stacks with Sneak Attack and similar sources.
