Fighting Styles
Defensive Fencer
When you are wielding a parry weapon and use your reaction to parry an attack, you add your proficiency bonus to your AC for that attack instead of the normal +1. In addition, when you make an attack with a parry weapon, you can choose to make a special attack with the weapon as a bonus action, a pommel strike:
Pommel Strike. On a hit, the target cannot take reactions until the beginning of its next turn. This attack deals bludgeoning damage equal to your Strength modifier (or Dexterity if the weapon has the finesse property) instead of the normal damage for the weapon.
