Prerequisite: Must have proficiency with shields
Your shield has become an extension of you and you're able to weave its use into the flow of combat both offensively and defensively. On your turn you can choose to use your shield in a bonus action attack as if it were a mace to bash your shield into your foe causing 1d6 damage plus applicable strength modifier. To do so sacrifices the +2AC benefit of wearing a shield until your next turn.
