Specialty Martial Artist [Fighter, Fast Hero, Strong Hero] 
You have mastered an unusual fighting style that turns normally harmless pursuits deadly.
   Prerequisite: Combat Martial Arts or Defensive Martial Arts
   Benefit: When this feat is selected, specify a Craft, Knowledge, or Perform skill. You are the master of a fighting style that weaponizes that activity. You add ½ your number of ranks in the designated skill (round up) to your to-hit and damage rolls when making unarmed attacks. You may use objects associated with the activity as improvised melee or ranged weapons without suffering a non-proficiency penalty. In general, the objects deal a base of 1d4 points of damage with a base crit range of 19-20.
   Special: You may select this feat multiple times. Each time, a different Craft, Knowledge, or Perform skill must be specified. You must declare which version of the feat (if any) you are using at the beginning of each round if making a martial arts attack.
