Shield Combat

You have learned to use your shield both offensively and defensively. Your shield becomes a weapon that deals 1d6(1d8) bludgeoning damage, has the thrown (20/60) and versatile properties, along with the sap mastery property. 

The fighting style "2 weapon fighting" applies to the shield and the fighting style "dueling" no longer applies unless the single weapon you are using is the shield.
