Sirene Primer+Free Or Non Actions+Fatal Thrust

Whenever you make an attack action or an attack of opportunity against a target that is within 30 ft. and that you are flanking, that is flat-footed, or that has lost its Dexterity bonus to AC (such as through a successful feint), you deal an additional +1d6 precision damage to the target. This damage is not multiplied on a critical hit. This damage increases by an additional 1d6 precision damage for every 5 points of base attack bonus you possess.

A fencer may apply the effects of a single (exploit) talent to any fatal thrust.
