Martial Strike
You can focus on dealing additional damage with your weapons
Prerequisite: Ability to take feats requiring fighter class levels
Benefit: As a swift action, you focus your efforts on dealing additional damage with your weapons. For 1 round, your weapons deal +1 damage. Additionally, you may add one weapon damage type (bludgeoning, piercing, or slashing) to the damage done for the purpose of overcoming damage reduction. For every +5 base attack bonus levels you possess, this bonus increases by +1, to a maximum of +5 at 20th level.

#Microfeats are quick sketches of rules I am considering for possible use in a 3pp Pathfinder-compatible product, which may be altered, adjusted, or never make it into a final product.
